Chapter XIX: Part 19

It is possible that both sides of the chest may be affected; but both sides may not be punctured in succession, for an error in puncturing both, or even the sonorous or sound side instead of the dull or affected side, has been almost immediately destructive of life.

318. The admission of atmospheric air into the cavity of the chest during this operation has been much deprecated, and many inventions have been recommended for its prevention, but it is scarcely possible to prevent some air getting in. It is often seen to do so; it has been proved by auscultation to have done so, and is usually absorbed in a few hours. In one case which I saw it gave rise to distressing symptoms from pressure on the lung, but was removed by a common syringe, to the great relief of the patient. In all these cases two things must be considered: Can the compressed lung expand so as to fill the chest when the fluid is withdrawn? The answer must be, in many cases it is so bound down by adhesions that it can dilate but slowly, if at all. If it be asked whether a vacuum is formed in the chest, the answer will be, no; and it will then be admitted, on consideration, that air always finds its way into the chest, and never does harm to persons in health. When mischief does ensue after an operation or an injury, it usually occurs from the irritation caused in a particular state of constitution, and not from the admission of air. A change in the appearance of the discharge has been frequently found to follow, and to depend upon, an accidental derangement of stomach, and to return to its more normal state on the derangement being removed. If the wound into a cavity can be closed and healed, the air will remain with impunity until absorbed. If the wound cannot be healed, unhealthy inflammation may be propagated from it to the whole cavity with which it communicates, but this is not the effect of the admitted air.

Dr. H. M. Hughes has published several cases of pneumothorax in the first part of the of the volume of “Guy’s Hospital Reports” for 1852. In the sixth case, which he calls a genuine example of pneumothorax from rupture of one or more of the vesicles of an emphysematous lung, the patient died speedily; and, on examination, he says: “It is also an interesting fact that no evidence of inflammatory action existed in the pleura, as it indicates that air in a healthy serous membrane does not excite inflammation;”--a Peninsular dogma I have been forty years inculcating, and which I trust is at last admitted as an established fact. How long it may be before it is generally taught, is another matter; for surgeons, like other men, often adhere with tenacity to preconceived opinions, however erroneous, particularly as they advance in life and have ceased to desire to learn more than they already know.

319. In all cases of _serous_ effusion, there can be little doubt that the fluid should be wholly evacuated and the wound closed. When the fluid is _purulent_, a permanent drain should be early established. It is not, however, common for the operation to be repeated several times without the serous discharge becoming purulent; and, in such cases, it usually becomes necessary at last to allow the wound to remain open until the discharge shall cease of itself. Whenever more than one opening is necessary, and the first is made between the fifth and sixth ribs, the succeeding ones should be made lower down; so that when it is thought right to leave the last puncture to become fistulous, it may be made as near the diaphragm as may be thought consistent with the safety of that part.

When a doubt exists as to the probability of more than one puncture being sufficient, and it seems likely that a third, or even more, will be required, the surgeon may anticipate this necessity by introducing a piece of soft gum-elastic catheter through the canula into the chest to the extent of about three inches, enough being left outside to admit of its being secured by tapes and adhesive plaster; through this a certain quantity of the fluid may be drawn off daily until it ceases to be discharged. The elastic tube bends with the heat, and applies itself to the inside of the ribs. If the lung should rub against it, which can be ascertained by a blunt probe, the elastic tube should be removed, and the external wound kept open by a softer plug. In all these operations, care should be taken to prevent the occurrence of inflammation. The accession of pain in the part, of difficulty of breathing, of fever, should be met by the abstraction of a few ounces of blood by cupping, by dry-cupping, by mercury in small doses, by rest, by diet, etc., and, if a tube have been introduced, by its removal.

The propriety of injecting stimulating or even simple fluids into the cavity of the chest has been often advocated, and as frequently repudiated. Warm water or milk and water is certainly admissible, and has been found very useful, particularly when there is an adventitious cause keeping up the irritation, which may possibly be brought to the opening by the sudden abstraction of the injection. Pieces of cloth and bits of exfoliated bone have been floated out by throwing in an injection of tepid milk and water. The opening, in a case of this kind, should be made between the eleventh and twelfth ribs behind.

Dr. Wendelstadt, of Hersfield, in the year 1810, in the twenty-third year of his age, suffered an attack of pleurisy, which became chronic, and ended in effusion. After severe suffering for six months, he was able to attend to his professional duties. The ribs of the right side protruded, but the intercostal spaces did not; the whole side was motionless on respiration taking place. The circumference of the chest continued to increase, and fluctuation within became evident on succussion. In June, 1819, having undergone another attack of pleurisy, he submitted to the operation for empyema, as offering some hope of preserving life. When a pint of fluid had been discharged, the wound was closed, and he experienced great relief. The next day a third of a quart was taken away twice in the day, and on the third day as much more; but he thought this was too much, as he became greatly exhausted, and feared that suffocation was impending. He was recovered by stimulants. On the fourth day the fluid was thicker in consistence, and fetid, and continued more or less so for a fortnight. It was then allowed to flow as it would at each dressing. Astringent injections were used for six weeks, but were then abandoned, and he gradually recovered his strength. Thirteen years afterward, in 1830, the wound was still open, discharging twice a day, sometimes only half a drachm, sometimes three or four ounces daily. The right side had altogether shrunk, and did not move on inspiration; he had no cough, and was otherwise in good health; a piece of a rib became loose, and was removed at the end of thirteen years, when the report of the case terminated, the patient being in health.

It may be remarked on this case, that the admission of air did no harm; that the lung remained compressed; that the whole side thickened and flattened, as a consequence, so as to obliterate the cavity; but the cure would not have been effected even then, if the piece of carious rib had not been discovered and removed.

Mr. Winter, secretary to Admiral Sir C. Napier, was wounded by two musket-balls, one in the arm, while the other entered between the inferior edge of the left scapula and the thorax, which it penetrated, fracturing a rib in its progress, and lodged. He fell, and spat up some blood, and as symptoms of inflammation supervened in twenty-four hours, he was bled largely; this was repeated frequently until these symptoms were subdued. He was after a time sent to the Marine Hospital, Lisbon, in a miserable plight, suffering from hectic fever, with a flushed face, hot skin, glassy eye, great prostration of strength, cough, restlessness, dyspnœa, and copious night-sweats. The wound discharged a watery, sanious, fetid matter in quantity, and he was unable to do anything but eat, and for food he had a great craving. From this state, under good treatment, he gradually recovered his strength, and on the 18th of June, 1834, a piece of the rib was removed. The wound remained open with a great purulent discharge, which kept him in a reduced state; a little more than one year after the injury, he reached London, and was taken into the Westminster Hospital. The left side of the chest was flattened and contracted, and the lung was doing very little in the respiratory way; the wound discharging a quantity of matter, which he could readily evacuate by making the opening the dependent point, but not otherwise. On enlarging the external wound, so as to make the opening into the chest direct, I found a round-pointed gum-elastic bougie could pass into it for four inches, and, on bending it down, for six inches more, it having to pass over a thickened pleura, and false membrane of an almost cartilaginous nature, for the extent of an inch, before it could be felt to be in a large cavity. As it did not appear that he had any chance of recovery, unless another opening were made lower than the sixth rib, in a more dependent position, I proposed the operation, but he would not submit; and after a time he left the hospital and went into the country, where he died.

A non-commissioned officer, of the 2d Division of cavalry, was wounded at the battle of Albuhera, on the 10th of July, 1811, in several places, by the lances of the Polish cavalry; one of these penetrated the left side of the chest behind, immediately below and in front of the inferior angle of the scapula. He spat and coughed up blood, and lost so much from the wound that he became insensible, the bleeding having been stopped by a part of his shirt being bound upon it tightly by means of his woolen sash. Brought to the village of Valverde, my attention was drawn to him some days afterward, in consequence of the difficulty of breathing having increased so that he was obliged to be raised nearly to an upright position, as well as from his inability to rest on the part wounded, round which a dark-blue inflammatory swelling had taken place, the wound having closed. An incision being made into it, a quantity of bloody purulent matter and clots of blood flowed from it. The incision was then enlarged, so as to allow of a direct opening into the cavity of the chest, which was kept open. The relief was immediate. He was removed to Elvas, apparently doing well, some three weeks afterward.

This case offered the nearest approach I have seen to the ecchymosed edema described by Valentin as accompanying effusions of blood into the cavity of the chest; and, as well as the following, is an instance of operations, not by election, but by necessity.

A French soldier had been wounded at Almaraz by a musket-ball, which went through the right side of the chest, in a line nearly horizontal from a little below and to the outside of the nipple, backward. The first symptoms having subsided, he gradually descended the Tagus to Lisbon, where, after some months of continual discharge, the wounds closed, first the back, and then the front. He did not recover his strength, always looking sickly, and suffering from pain, difficulty of breathing, and other inconveniences, which did not prevent his walking about in the confined space to which he was doomed as a prisoner of war. My attention was drawn to him in consequence of an obvious fullness of the intercostal spaces, of the great difficulty of breathing, and of a puffy inflammatory swelling which was forming around and at the seat of the wound in front. Through this I made an incision into the cavity of the chest, the walls of which, on introducing the finger through the opening, appeared to be very much thicker than usual. A large quantity of pus was discharged, and the man was relieved, but this amelioration was not of long continuance, and he gradually sank and died. On opening the body, the inside of the wall of the chest was found to be half an inch in thickness, in consequence of a firm deposition on the pleura, of a yellowish-ash color, honey-combed or ulcerated, as it were, in plates, particularly where the opening had been made. The lung was shrunk up from the anterior and lower part of the chest, but adhered to the wounded part behind, and was covered by a layer of false membrane of considerable thickness. The wound through the lung could not be distinctly traced, from its being diseased throughout.

At Santander, in October of the same year, 1813, I received some eight hundred wounded in the affairs of Le Saca, Vera, etc. One of the Light Division had been shot through the left side of the chest: the posterior wound had closed, but a sufficiently large quantity of matter was discharged through a small anterior one to show that there must be some depot from which it proceeded. The wound was laid open into the cavity of the chest, and free vent given to a quantity of matter. Some small pieces of rib were discharged, and a bit of something like the cloth of his coat also came away. He could lie on either side, and hopes were entertained of his recovery, until after I left Santander in December, to join the army in France, when he suffered a relapse of inflammation, and died.

A soldier of the German Legion was wounded at Waterloo by a lance between the sixth and seventh ribs of the left side. He spat up much blood for several days, and was carried to Antwerp, where he remained for several months, suffering from great difficulty of breathing and other distress in his chest, which recurred from time to time, although the wound had healed. He was admitted into the York Hospital, Chelsea, in the spring of 1816, in consequence of an attack of inflammation, of which he died. On examining the body, the lung of the right side was found to be greatly inflamed, and full of purulent fluid, which caused his death. The left or wounded side was found to contain a small quantity of pus, the cavity being very much diminished by the great thickening of the pleura and the falling in of the ribs, which were thicker, greatly flattened, and changed in form; the lung, shrunk or collapsed, was covered by a thick adventitious membrane, and bound down against the spine, leaving a long, small space between the pleuræ, which once had doubtlessly been full of matter. The mediastinum and heart appeared to lean toward the left side, aiding in this manner in the obliteration of the cavity, which must take place if a permanent cure be effected in empyema. I have seen two cases in which this obliteration appeared to be complete: one in a soldier, who had been wounded in the chest; the other in a gentleman, the subject of empyema, in private life. In both the spine was also distorted, the side wasted, the nipple lower than the other. The breathing of the opposite side was more marked and developed. It might have been called puerile.

320. _Pneumothorax_ means an effusion of air and of the matter of a tubercular abscess from disease into the cavity of the chest, or from an injury or a wound in the lung. When pneumothorax is the consequence of disease of long standing, the patient may be sensible of a sudden pain, which does not abate, and which is accompanied by an equally sudden increase of the difficulty of breathing, for which he cannot account. He feels relief by lying on his back or on the affected side, rarely on the other, although the difficulty of breathing may increase, so as to render the further continuance of life doubtful, while the prostration of strength is considerable. The muscles of respiration are all in rapid and powerful action; the heart is displaced to the right side when the complaint attacks the left, and it will be displaced somewhat to the left when the right is affected; in some cases it even descends into the epigastrium, or is otherwise removed from its natural situation, even toward the axilla, although the left side is supposed to be more obnoxious to this complaint than the right. The pulse becomes exceedingly quick and small, countenance pale, nights sleepless. The affected side is oftentimes evidently dilated, and the intercostal spaces may be less marked, or partly filled up, when the respiratory motion given to the parts under ordinary circumstances is seen to be deficient. But these differences, as well as that which can be obtained by comparing both sides by measurement, are not so marked as when the cavity is filled with fluid, of which in pneumothorax there is always a small quantity effused.

_Percussion_, beginning from above, in the erect position, will give, in cases in which it is ascertained that respiration is null, a clear tympanitic sound, as low as the level of the fluid, when it changes abruptly to a dull sound, or that indicating the presence thereof. If the patient be then placed in the recumbent position, the clear sound can be heard above, the dull one below, demonstrating the change in the situation of the air and fluid. _Auscultation_, in addition to the absence of respiration, when the chest is fully expanded, discovers no respiratory murmur; but a peculiar sound called _tintement métallique_, or metallic tinkling, is heard at intervals, particularly on the patient’s coughing, speaking, or breathing. It may be imitated by dropping a pin into a large wine-glass, but it more nearly resembles the sound of a jew’s-harp in the hands of a child: once heard it cannot be mistaken. It is a sound distinctive of pneumothorax.

“Mr. Cornish, a medical practitioner, having suffered an attack of pleuritis, nearly expired from suffocation on Monday, the 29th December, 1828. He was lying on his right side, breathing most laboriously; countenance sunk; pulse between 130 and 140; had had no sleep for many nights. The action of all the respiratory muscles was painful to behold; no perceptible difference in the size or shape of the two sides. The _right_ emitted an extremely dull sound; the _left_ sounded hollow throughout. The apex of the heart was beating rather to the right of the right nipple. The respiration was loud and rattling in the _right_ side; metallic tinkling distinct in the _left_; expectoration muco-purulent, with specks of blood, and many black particles. Mr. Guthrie, who saw him for the first time, made a short incision between the sixth and seventh ribs, and cautiously opened the pleura, when a rush of air issued forth with a hissing noise, strong enough to have extinguished several candles. The patient turned on his back, breathed with comparative freedom, and expressed his gratitude for the operation. No fluid issued from the wound when made a dependent opening. On the 31st, the difficulty of breathing and the metallic tinkling had returned, the wound having closed. The wound was reopened and enlarged; the pulse fell to 120; the metallic tinkling ceased to be heard; the patient took some nourishment and an opiate at night.

“Jan. 1st, 1829.--Has slept several hours; breathing easy; pulse reduced in frequency; appetite good. A canula was placed in the wound, when large quantities of air came through it on each expiration; the heart beat two inches nearer the central line of the thorax than before. During the night he became greatly oppressed, and died next day. On raising the sternum, the heart was found rather to the right of the median line of the chest. The left lung was collapsed to one-fifth of its natural dimensions. The vacant space was filled with air, and about fourteen ounces of turbid serous fluid. The pleuræ costalis and pulmonalis presented marks of inflammation of a few weeks’ standing--viz., some thin false membranes, which were easily separated by scraping with the scalpel. There were no marks of more recent pleurisy. A tube was inserted into the trachea, and air blown into the lungs. The left lung expanded to a certain extent, and air was heard to bubble out, when an aperture was immediately recognized at the division between the two lobes, through which the air rushed forth and extinguished a taper that was held near it. The aperture was circular, fistulous, and capable of admitting a crow-quill, and was found to communicate with a very small excavation, formed by the softening down of some tuberculous matter; into this small excavation a bronchial tube was seen to enter. Thus, the communication between the trachea and the cavity of the chest was distinctly traced. The left lung presented some trifling tuberculation, but was not materially diseased.”

William Griffin, aged eighteen, was admitted into the Westminster Hospital on September 14th. Ten days before his admission into the hospital he discharged a pistol against the left side of his chest, causing a wound corresponding to the middle of the eighth rib, from which a very small quantity of blood escaped. The medical practitioner who was called to him at the time _passed a probe to the extent of four inches_ into the wound. The wound had nearly cicatrized, but he became the subject of acute pain, diffused over the whole of the left side of the chest, accompanied by fever and frequent cough, dyspnœa, and inability of lying on the right side. After the lapse of a week he was transferred by his surgeon to the medical wards under Dr. Roe, at which time he had begun to expectorate purulent matter of an extremely fetid character, occasionally mixed with blood. His respiration was hurried, the right side of the chest expanding much more freely than the left; the lower three-fourths of the affected side were dull on percussion; tubular respiration could be detected at the upper part, but at the lower no air appeared to enter; well-marked modifications of voice existed over the whole of that side of the chest. By measurement no difference in the relative size of the chest was observed, but the intercostal spaces of the left side remained motionless daring expiration. The heart could be felt feebly pulsating at the epigastrium.

October 15th.--He suffered from a violent paroxysm of coughing, during which great dyspnœa suddenly came on. He sat propped up in bed; respiration was almost ineffectual, his face livid and covered by a cold, clammy sweat, pulse scarcely perceptible at the wrist, and his extremities were becoming cold. On examining the chest, the left side, before quite dull, now afforded tympanitic resonance on percussion, which, together with the total loss of respiration and the presence of metallic tinkling, proved the existence of pneumothorax. A trocar was introduced between the sixth and seventh ribs, and was followed by an escape of gas with about five drachms of pus, both of a very fetid character; the canula becoming obstructed, a larger one was then passed through the opening, but not more than half an ounce of pus escaped; it was then withdrawn, and found to be blocked up by what appeared to be disintegrated lung. Being greatly relieved, no further attempts at evacuating the fluid were then made.

At night, during a paroxysm of coughing, six ounces of fetid pus escaped by the opening, after which he felt relieved. A second gush of sanious fluid, to the amount of five ounces, containing small masses of sloughing membrane, subsequently took place. Cavernous respiration at the upper half of the lung, mixed with gurgling and metallic tinkling. Expectoration muco-purulent and offensive.

21st.--Has somewhat improved, but suffers from accessions of fever toward evening, and perspires very profusely during the night; the cough is less frequent, and he expectorates freely, the sputa being of a purulent, fetid character. Scarcely any discharge from the side.

Nov. 5th.--Has remained in nearly the same condition until yesterday, when he ceased to expectorate, and has since become much worse; his skin is now intensely hot; face flushed; tongue brown and coated; pulse jerking, but feeble and frequent; the opening in the chest has quite healed.

A second opening was now made about an inch external to the former one, and a canula introduced, but not more than one ounce of pus escaped, the instrument becoming blocked up by portions of sloughing tissue; during a paroxysm of coughing, which occurred a few hours afterward, several ounces of fetid sanguineous pus were forced through the wound.

16th.--Since the last report he has been slowly sinking--is emaciated to an extreme degree. The wound originally produced by the pistol-ball, as well as those made by the trocar, have become fistulous, so that during respiration the air passes into the chest, and is expelled with as much freedom as that passing by the trocar. Expectoration has continued very copious, about a pint and a half having been passed in every twelve hours; large sloughs have formed upon the nates and hips, his intellect wanders, and he has frequent syncope. Died on the 5th of December.

_Sectio cadaveris._--The pleural cavity of the left side contained about ten ounces of purulent matter mixed with blood, and floating in it were numerous masses of white, curd-like matter, at the bottom of which, in the angle formed by the diaphragm with the spine, was found a pistol-ball partly covered by albuminous matter and discolored. Fluid injected into the left bronchus was found to issue freely from an opening at the most depending part of the lung, communicating with a small cavity, the interior of which was lined by the same thick membrane met with in cases of chronic phthisical disease; from the upper part of this cavity two other sinuses were formed, the one passing externally and terminating by an adhesion of the lung with the ribs at the point where the ball had entered; the other was longer and more tortuous, passing deeply in the substance of the lung, and ending in a large abscess capable of containing five or six ounces of pus. The lung was at its lower part firmly attached to the ribs by intervening false membrane, while the upper part was free, and had become compressed toward the spinal column. The substance of that part of the lung not involved in the abscess was infiltrated with pus, and the greater number of the bronchial tubes were filled up by masses of curdy matter similar to those found floating in the effused fluid. The natural division of the lung into lobes was quite destroyed by the pleuritic adhesions of one to the other, while the pleura lining the parietes was covered by rugged layers of false membrane of irregular thickness, but readily detached. No trace of tubercular deposit could be found, and the lung of the opposite side was quite healthy. Since the first publication of these cases the operation has been so frequently and, in many instances, so successfully performed, as to leave no doubt of the advantages to be derived from it.

321. Lord Beaumont was wounded by a pistol-ball on the 13th of February, 1832, when standing sideways. It entered the right side of the chest a little below the nipple, appeared to pass under the lower end of the sternum, just above or about the xyphoid cartilage, and to have lodged in the cartilage of the last of the true ribs of the left side near its junction with the bone, in consequence of a round projection at that part resembling a pistol-ball, but which, on being exposed, showed only a knob of cartilage which might have been a natural formation; no further steps were therefore taken. The injury had been received about four o’clock--it was now five; he could lay flat on his back; had little or no pain or oppression.--Seven o’clock: Breathing became oppressed, and accompanied by pain; vesicular murmur distinct in both lungs; pulse 96; bleeding to thirty-two ounces.--Nine o’clock: Difficulty of breathing; the pain greater; was again bled until the pulse failed, although he did not faint; the relief great.--Half-past ten: Oppressive breathing again returned; pulse very low and quick; thirty-six leeches applied; relief obtained.--Half-past twelve: Thirty-six more leeches.--Half-past two: Thirty leeches were again applied. In all, four pints of blood were taken from the arm, and one hundred and two leeches were applied to the chest, the bleeding being encouraged afterward; during the first ten hours live grains of calomel and four of the compound extract of colocynth had been given, and now forty minims of Battley’s solution of opium were administered.

14th.--Eight o’clock: Slept after four o’clock; on waking took an aperient draught, and is much easier; pulse 120, soft, small, and weak.--Three P.M.: On the dyspnœa returning twenty-one leeches were applied, and the oppression was relieved; an enema given, which acted freely.--Half-past twelve: A returning oppression relieved by eleven leeches; calomel repeated, and thirty minims of solution of opium.

15th.--Eight A.M.: Slept at intervals; little or no expectoration, no blood; thinks he would faint if he sat up in bed; pulse 130, soft, small, and weak; little pain; lies tolerably flat; respiratory murmur distinct on both sides.--Nine P.M.: Oppression returned; twenty-four leeches; repeat calomel and colocynth; an enema, after which the bowels became free.--Evening: Six grains of calomel, and opium draught.

16th.--Eight A.M.: Had forty-eight leeches applied at intervals twice during the night; slept at intervals, and is easier; no pain in the chest; pulse 108.--Evening: An enema; six grains of calomel, and one grain of opium.

17th.--Eight A.M.: Slept during the night, and is better; pulse 108, soft; breathes freely; no pain.--Evening: Has had leeches applied twice during the day, making in all 245, and each time with relief; an enema,--calomel and opium as before.--Twelve at night: More oppression, and, as the pulse was fuller and quicker, a vein in the arm was opened, but only four ounces of blood could be obtained.

18th.--Eight A.M.: Slept at intervals, although very restless; pulse 120, fuller; oppression in breathing returning; bleeding to twenty ounces, which caused him to faint; senna draught.--Evening: Has been much relieved by the bleeding; blood cupped and buffy; twenty leeches; enema; calomel and opium. In the night, at two o’clock, the dyspnœa returning, twenty-two leeches were applied, and thirty minims of solution of opium given.

19th.--Eight A.M.: Easier, quieter, better; pulse 110, soft; can lie quite flat on his back. The wound discharged so little that the external parts were dilated inward toward the sternum, until the pulsation of an artery could be seen, perhaps the internal mammary, which it was not thought advisable to disturb; respiratory murmur not distinct at night; enema; calomel, opium, and twenty leeches.

20th.--At three in the morning, being greatly oppressed, thirty leeches were applied, and at eight o’clock twenty more, which quite relieved him, but left him in a state of great exhaustion, sick, and faint. A little arrow-root relieved the faintness; discharge from the wound free, and accompanied by _air_; bowels open.--Ten at night: Calomel, and forty minims of the solution of opium.

21st.--Eight A.M.: Has now, for the first time, a hope of life: pulse 112, soft; no pain; can turn on his side, but fears to hurt himself; wound discharges freely; has had a small piece of bread for the first time.--Four P.M.: Restless, but better; senna and sulphate of magnesia mixture.--Eight P.M.: Oppressed; pulse 120; twelve leeches; calomel, and thirty minims of the solution of opium, at night.

23d.--Oppression at night relieved by six leeches; slept afterward; breath slightly affected by the mercury, which was omitted in consequence; ten grains of the compound extract of colocynth given at night, with thirty minims of the solution of opium.

25th.--Free from pain; breathes easily and without difficulty; can turn in bed with ease; slept well; the discharge from the wound is free; takes farinaceous food, oranges, tea, etc. He gradually improved until the 13th of March.--On the previous Friday, the 9th, he removed from Bond Street to Mount Street; and on the 13th, amused himself by washing all over in a small back room without a fire; caught cold, and acquired a troublesome cough, which was quieted on the 14th, at night, by opium.--On the 15th, A.M., it was evident that some mischief had been done; pulse 120; breathing difficult; was bedewed with a cold sweat; respiratory murmur indistinct on both sides; on the left, not heard below the fourth rib; although the whole side sounded sonorously, it evidently contained air, the _tintement métallique_ being very remarkable. The wound having closed very much, and the distance to the left cavity of the pleura under the sternum being considerable, a piece of sponge tied around the eye of a small gum-elastic catheter was introduced, so as to enlarge the track of the ball, and give passage to the air from the left side of the chest. This was done at five o’clock P.M., and at ten, on its being withdrawn, air rushed out in a very manifest manner, to his great relief. The metallic tinkling, which was distinct before the instrument was withdrawn, instantly ceased, but could be reproduced by closing the opening. The small gum catheter was therefore reintroduced with the eye projecting beyond the sponge, and retained, air passing through it; cough very troublesome.

March 17th.--Better; pulse 100; bowels open; cough easier; expectorates freely a _rouillée_, or reddish muco-purulent matter.

18th.--Easier and better; breathing on the left side not heard below the fourth rib; discharge free; the permanent gum catheter taken out, but passed in daily. After this he slowly recovered, and continued to enjoy good health until the summer of 1854, when he died of what was supposed to be ulceration of the stomach, being an admirable instance of the treatment to be followed in such cases. When there is not an opening to enlarge, one should be made with the trocar.

It has been stated by the latest writers on pneumothorax, that tympanitic resonance on percussion, and the absence of respiration, are not pathognomonic signs of pneumothorax, as these physical signs may exist without it, and pneumothorax may exist without them. The metallic tinkling, in addition to the absence of all appearance of disease in the abdomen, will be conclusive of the presence of this disease.

322. Emphysema, from εν and φυσαω, to inflate; the diffusion of air into a part of or throughout the cellular tissue of the body. It has been said to take place after a wound of the chest, but without an injury of the lung, from the air passing through the wound into the cavity during inspiration; and by accumulation and subsequent compression under the act of expiration, giving rise to all the symptoms of the disease; a complaint more theoretical than real.

Emphysema, as a medical disease, is opposed to the surgical disease, in not being an extravasation of air into the cavity of the chest, but a dilatation of the air-cells formed for its reception. It is of two kinds, _Vesicular_ and _Interlobular_--vesicular when dependent on the enlargement of one or more air-cells; interlobular when, from the sudden rupture of an air-cell, the air has found its way into the interlobular structure of the lung. A third and very rare kind has been added, in which air, being extravasated under the pleura, has raised it in the form of a pouch. The morbid appearances these diseases afford, and the symptoms they give rise to, do not fall within the range of surgical skill; and are not frequently within the controlling power of medical science and ability.

Emphysema is free from redness, and is distinguished from edema, or the swelling containing a serous fluid which is also colorless, by its not pitting on pressure, or retaining the mark of the finger. It is, on the contrary, elastic; and the displacement of the air, on pressing on the part, gives rise to a peculiar noise, resembling the crackling of a dry bladder partly filled with air on its being compressed, usually called crepitation. This swelling extends as the air introduced increases in quantity until the whole of the areolar tissue of the body may be fully distended.

Emphysema most commonly occurs from fractured ribs, a point from one or more of which abrades the surface of the lung. Through the opening thus made, the air escapes into the sac of the pleura, and thence by the side of the broken part of the ribs into the cellular membrane. The distress in breathing arises from the air being diffused over the surface of the lung, which it gradually causes to collapse under the pressure exercised by the act of expiration; while, at the same time, the mediastinum yielding, the opposite lung suffers in a similar way, although to a less extent, until the aerification of the blood is so greatly obstructed as at last to interfere with life, unless relief be obtained by the equalization of the pressure made on the lung by the compressed air in the cavity of the pleura, with that exercised on the inside of the lung through the glottis.

In ordinary but not severe cases of fractured ribs, a slight degree of emphysema is frequently observed over the injured part, implying that the lung has been wounded; such a case requires the application of a compress, wetted with a little spirit and cold water, retained by a bandage. The great art in the treatment of broken ribs by compress and bandage consists in their proper application, which can only be ascertained by the feelings of the patient. The application of a broad flannel bandage, so as to restrain the motions of the chest, and to cause the sufferer to breathe by the diaphragm, has been recommended from the earliest periods of surgery; but many persons with injured or broken ribs cannot bear the pressure of a bandage, while others derive much ease from its use. A tight bandage generally disagrees when the injury has been sustained at the lower part of the chest, and is more frequently useful when the fracture is above the fifth or sixth rib.

When the emphysematous swelling extends so as to invade a considerable portion of the body, the further diffusion of air should be prevented by punctures made through the skin in such places as may be thought necessary, and in extreme cases even by incisions; but these are things more often spoken of and written about than practiced, or than are even necessary.

323. Mr. J. Bell had so alarmed all military surgeons by stating, in his able discourses on the Nature and Cure of Wounds, that emphysema was “peculiarly frequent in gunshot wounds of the chest, both at the orifice of entrance and of exit of the ball,” that they thought of little else. They could not withstand the brilliant manner in which this remarkable error--for error it is--was expressed. To such of us as had served in the first part of the war in Portugal it was no longer a bugbear; we slept in peace after the battles of Roliça and Vimiera, of Corunna, of Oporto, and Talavera--laughing, perhaps, a little at the credulity of the surgical portion of mankind; for the opening made by a musket-ball rarely admits of emphysema. A slanting wound made by a pistol-ball may sometimes give rise to it. After long and tortuous wounds made by swords or lances it is seen more frequently, but then it takes place shortly after the receipt of the injury.

A soldier, at the battle of Albuhera, was wounded in the right side of the chest by a sword, which had passed slantingly under the shoulder-blade, from which injury he did not suffer much, until the whole side as well as the body and neck began to swell and impede his breathing, which was effected with some difficulty and with any ease only when sitting up. The external wound was enlarged until I could distinctly hear the air rush out and see the part where the weapon had penetrated between the ribs; upon which he declared himself relieved, when the wound was closed by compress and bandage. It did not unite, however; active inflammation of the cavity of the chest ensued, requiring frequent and considerable losses of blood for its suppression. At the end of three weeks the man was sent to Elvas, in a favorable state for recovery.

324. When an opening is made into the cavity of the chest in the dead body, the lung recedes from the pleura lining its wall, for some distance; it is said to collapse; but this does not take place in anything like the same extent in the living body; and if the continued admission of air through the wound be prevented, it scarcely takes place at all; or, should it have done so, the air is usually absorbed and the lung quickly recovers its natural dimensions and functions. Neither does a wound in the chest, when kept open, usually cause this collapse to the extent which it is generally supposed to do in the living body. The lung can be seen in motion and performing its office, although imperfectly, as it does not fill the cavity of the pleura. When the lung has been wounded by a ball actually going through its substance, it does not necessarily collapse; and abrasions or deeper injuries of its surface lead to no such result. To cause the complete collapse of a living lung, its surface must be compressed by a fluid, as in empyema, or by confined air, as in emphysema or in pneumothorax.

In extreme cases, when the patient can no longer lie down, but sits up, supported, in the greatest agony of respiration, approaching to suffocation, the face and lips swollen and blue, the pulse almost imperceptible and countless, an opening should be made into the chest by a small trocar and canula, for the purpose of evacuating the highly compressed and compressing air, and to allow the expansion of the lung after its evacuation. When this compressed air has been drawn off, as in the case of Lord Beaumont, the compressing power being removed, the lung expands in part, if not entirely, in spite of the breach in it, and the mediastinum and heart return to their natural situation, the distress in breathing is removed, the failing circulation is restored, and the opposite lung resumes its functions.

The course then to pursue in such extreme cases is merely to puncture the chest, evacuate the air, withdraw the canula, and close the opening. The life of the patient having been thus saved, time is given for the wound in the lung to heal under the usual inflammatory processes, provided it will do so without a recurrence of the mischief. This, if it should take place, must be met by another puncture, or the opening in the chest should be made permanent in order to equalize the pressure of the air in the cavity.

The incisions (the “_taillades_” of the French) into the cavity of the chest formerly recommended, should only be resorted to when the means indicated have failed, which they will rarely do when combined in the first instance with an antiphlogistic treatment, aided by sedatives, and if necessary by cordials.

The advantages to be derived from auscultation in these cases are evident. Its value has been sufficiently shown, and the ear or the stethoscope should be resorted to at least three times in every twenty-four hours, in every case, however trifling it may appear to be, until the absence of danger has been ascertained.

LECTURE XXII.

SIMPLE INJURIES OF THE CHEST, ETC.

325. The most _simple injury_, perforating the wall of the chest, is a stab by a triangular sword, a small knife, or other weapon, which may or may not abrade the surface of the lung, and which is usually attended by little pain, although it often gives rise to considerable alarm. It might be supposed that a very slight wound of the lung would be followed by some expectoration of blood, but this does not always take place; and although its presence may be considered demonstrative of the injury, its absence is no proof of the contrary; for a considerable injury from a stab or from a musket-ball may be inflicted, with scarcely any sign of blood in the matter expectorated. If the pleuræ are in their natural state, a small quantity of air may enter the chest, but the opening will require to be direct and tolerably large before the lung will separate or shrink from the wall on that account; if adhesions should have been previously formed between the pleuræ preventing it, they will be for the advantage of the sufferer.

In a simple incised wound, injuring the lung perhaps extensively, as supposed from the bleeding from the mouth, no examination by probes or other instruments need or ought to be made as a general rule; but the wound should be immediately closed by sutures after the external parts have been sufficiently examined to satisfy the surgeon that no portion of the offending instrument has been broken off, or other extraneous matters are sticking in the part.

The advantages derived from the closure of punctured wounds of the chest in former times led to the practice of sucking them by the mouths of irregular practitioners, generally the drum-major of the regiment, when the patient was a soldier; and the consequences, although in some instances apparently miraculous, were in others quite as unfortunate.

That bleeding may take place from the lung into the cavity of the chest is indisputable, but little or no blood will escape through a small wound; and its continuing to flow from such a wound will be a presumptive if not a conclusive proof that some artery external to the pleura has been wounded. Sucking, under ordinary circumstances, of a small wound, unattended by bleeding, does good by attracting the natural fluids to the parts, and thus causing them to swell so as to be placed in apposition in the most advantageous manner for their reunion. Punctured wounds of small size, therefore, may be sucked chirurgically if any one be willing to do it, after which a bit of gold-beater’s skin, or dry lint, should be placed upon the wound, supported by a compress covered by adhesive plaster; these dressings should not be removed for several days.

326. The patient should lie on the wounded part, as a general rule, if he can conveniently bear it, not for the purpose of allowing any effused blood or fluid to flow out, unless some particular reason require the precaution of keeping the wound open, but to allow the pleura covering the lung to be as closely applied as may be to the pleura lining the wall of the chest, with the hope that the adhesive process may take place between these parts, and by this means cut off the wound from the general cavity of the pleura, a proceeding due to the practice of the Peninsular war, yet so little attended to at the present time by some teachers of surgery, who seem to confound the practice thus recommended in incised wounds penetrating the cavity of the chest with that which should be adopted in gunshot wounds, that few students obtain even a reasonable degree of knowledge on this subject. Teachers are entitled to prefer any mode of treatment they please, but they should be careful not to neglect the opinions of others, whose authority, derived from experience, they are bound at least to notice, even if it should be to disapprove.

327. _Incised_ wounds of even greater extent ought not to be examined by the probe or finger; no disturbance of any kind should be permitted unless the cartilage or bone be injured. The external parts should be brought together as closely as possible, so as to facilitate in every way their union, and the processes which it is desirable should go on within. The external parts or skin and cellular membrane cannot be kept in perfect and continued apposition without sutures, and the proper method of proceeding is to sew up the wound in the skin with a needle and fine silken thread in a continuous manner, including absolutely nothing but so much of the cut edges as will retain the thread; a small piece of gold-beater’s skin or lint should then be laid over the stitches and retained by a compress and adhesive plaster.

In a _simple_ case of this kind little or nothing is effused into the cavity or secreted from the membranes of the chest, which will interfere with the processes which may have happily begun, and which it is desirable should be aided by the absolute quiescence of the patient, to whom no medicine should be given which may render any movement of the body necessary. It was formerly supposed that the greatest object to be attained was the prevention of inflammation, and a man was no sooner stabbed by his opponent than he was blooded and purged by his surgeon, regardless of the necessity which existed for perfect rest and the presence of a certain amount of inflammation, in order to enable nature to carry on those processes which are essential for the restoration of the injured parts. This inflammation should be allowed to commence without interference and to continue in a moderate degree until the object shall have been effected. It should only be interrupted or subdued when it is supposed to be about to exceed that degree which experience has pointed out as likely to be useful.

328. When the most courageous persons are wounded in parts essential to life, there is more or less alarm or shock created by the injury; although it has been gravely argued that a man does not always know when he is actually shot or run through the body. A continued state of anxiety and depression after an accident of this kind is a disagreeable accompaniment of the injury, during which little should be done beyond the giving a little cordial, and quieting the apprehensions of the patient, leaving him to rest, if possible, after the necessary applications have been made. If a gradual improvement take place, if the pulse rise, if the patient resume more of his natural appearance, and that state of commencing excitement which is denominated reaction follow, hope may then be entertained. The general symptoms, as long as they continue within ordinary bounds, are of little importance; the local ones, significative of action commencing in the injured part, are, however, to be carefully watched. They are those of inflammation of the pleura, and it may be of the lung. This inflammation begins slowly, and a day may elapse before it is well marked; for, when persons have died within the first few hours after such injuries, the pleura has often shown but little sign of inflammatory action. Auscultation should always be resorted to from the moment of injury, and constantly used throughout the treatment. Whenever it is concluded that adhesion between the two pleuræ has failed to take place, the direction to lie on the wounded side ceases to be of importance. Until this period no food whatever should be allowed, and thirst should be allayed by small quantities of water.

329. A punctured, incised, or gunshot wound, going fairly through both cavities of the chest, is usually believed to be quickly if not immediately mortal--an opinion generally correct with respect to wounds made by musket-balls, although it is certainly not the case with regard to punctured wounds, and does not always occur in those made by pistol or musket-balls.

Sergeant-Major Richards, of the 29th Regiment, received thirteen sword or bayonet wounds, and other injuries, on the heights of Roliça, on the 17th August, 1808--one particularly through each side of the chest, between the ribs, as if the small-sword had made a wound of larger size than usual. He had distinguished himself greatly in covering the body of his commanding officer, and was beaten down before the British column, which had been repulsed, could rally and recover its ground. He was an object of particular attention to me, for the few minutes he lived after I saw him; he had coughed up a little blood, and died gasping, as if suffocated, the chest laboring on each side to do its work in vain. His commanding officer, Colonel the Hon. George Lake, lay dead by his side, killed instantaneously by a musket-ball, which passed from the upper part of the left through the right side of the chest.
