Elements of Surgery

by Robert Liston

breathing through artificial openings in the larynx or trachea are peculiarly subject, probably from the inspired air not being heated, as in natural respiration, before it enters the bronchial tubes. A view from behind is here introduced of the larynx of a patient who some weeks previously attempted suicide by wounding the forepart of the neck. By some mismanagement the edges of the incision were kept asunder, and they cicatrised. The patient was seized with difficult breathing, the inspirations were rare, long, and laborious; he had threatening of suffocation during his disturbed sleep. These symptoms were disregarded. He started up suddenly in the night, caught hold of the patient in the next bed, and fell down in a state of asphyxia, from which he could not be recovered. The œdematous swelling of the rima glottidis is remarkable; beyond that is seen the rounded opening betwixt the thyroid cartilage and epiglottis, which is in a normal state.

The bleeding is to be arrested as speedily as possible by ligature, and the patient placed in bed with the head and shoulders raised. The edges of the wound are brought together by attention to the position of the head; but, provided the patient breathes easily with the wound open, closure should not be attempted till after eight, ten, or twelve hours—that is, not until all oozing of blood has ceased; the time depends on the extent to which the air-tube has been divided. There is little chance of immediate union taking place; and the wound not being approximated when recent and bleeding, does not diminish the chance, but on the contrary augments it. Adhesion is prevented by the insinuation of air and mucus betwixt the edges, by frequent motion of the edges on each other, by the slightest change in the position of the head, either rotatory or nodding, by the action of the muscles of the os hyoides, and by attempting to swallow food or saliva. Every circumstance is opposed to complete approximation and immediate union of transverse wounds of the throat.

Plasters and bandages surrounding the part are inapplicable, and unwarrantable from the interruption thereby caused to breathing and circulation; they likewise prevent the escape of mucus and air. Emphysema is apt to occur in consequence, and may prove troublesome; the cellular tissue of the neck becomes filled, so as to interfere with free respiration, and the infiltration of air extends over the face and chest. Neither can many stitches be used without bad effects. The corners of an extensive wound may be kept together by points of suture; and one may be placed at the middle, through the integuments only, to prevent overlapping or inversion of the edges. The head is placed in a comfortable position, inclined forwards, and secured by a bandage passed round it, with the ends brought down and fixed to a band round the chest. In many cases the patient requires to be watched attentively, to have the motions of his hands restrained by proper means, in order to prevent him from interfering with the wound, or committing other insane acts which might prove dangerous. The state of the breathing and of the pulse must be strictly attended to; inflammatory symptoms must be actively combated, and swelling prevented from gaining a dangerous extent, by bleeding, general and local. But depletion is indeed very seldom necessary, the loss of blood in the first instance proving a pretty effectual preventive of inflammation; it is more frequently requisite to administer nourishment or even stimulants; but these must be given gradually in those advanced in life, and in those who have lost much blood.

The slightest difficulty or noisiness of breathing must be closely watched, and on the occurrence of any alarming symptoms, energetic measures adopted. Swelling about the wound, producing difficult expectoration and a diminished current of air, may require the making of a longitudinal opening into the trachea below the wound, and the insertion of a tube. Thus the respiration is quickly relieved; and the patient is soon able to regulate the size of the aperture; he is readily taught to apply his finger over part of the orifice of the tube, when it is wished to clear the passage from mucus. The operation of tracheotomy should be had recourse to in such cases without hesitation or delay; there is no danger from its performance, but much from its being withheld.

If the mouth or gullet have not been opened by the cutting instrument, or only slightly, the patient may be allowed to swallow naturally; though it is true that even the slightest motion of the parts affects the wound injuriously. But, as already observed, immediate union is not to be expected; swallowing, or attempting to swallow, saliva, produces an involuntary action of the muscles, quite as prejudicial as the swallowing of liquids in large quantity does; and these motions cannot be prevented, since the patient has no control over them. If the wound of the mouth or gullet is extensive, portions of the ingesta are apt to interfere with the air-tube, particularly if the wound is high, and the epiglottis cut away or difigured. In such cases, soups and other nutritious fluids are conveyed through an elastic tube, passed by the mouth over the root of the tongue to beyond the injured part, and introduced only when it becomes necessary to administer food; or a small tube may be passed by the nostril, and retained. If the wound is very severe, and the necessity for thus conveying nourishment likely to continue long, the latter method is adopted; it is more difficult in execution than the former, but when the instrument is once passed, no further trouble is given to either the patient or surgeon. Small quantities of nourishment are to be given frequently, of such strength as the symptoms indicate; many patients have died from inattention on this score.

Many have died suddenly and unexpectedly (though this should not be, if symptoms and circumstances were attended to) from the effects of apparently slight wounds; whilst others have recovered, when recovery was unlooked for, after dreadful injuries, and these perhaps not treated in the most approved manner. In illustration, I shall briefly detail, though it did not fall under my own observation, an interesting and remarkable case of recovery. A criminal under confinement attempted suicide by transverse wound of the throat. The larynx was severed at the upper part of the cricoid cartilage, and the cut extremities had retracted at least three inches; the œsophagus was also cut across, but the extent to which it had receded was not ascertained. A large quantity of blood had been lost; attempts were made to bring the parts together, but were abandoned on account of the violent dyspnœa which was induced. The attendant endeavoured in vain to pass an elastic gum tube into the gullet, from the nose and from the mouth. The patient was kept alive by nutritious enema. On the second day after the accident, the cut extremities of the larynx were approximated by two ligatures; and, the retraction being thereby diminished, it was then discovered that there was another wound between the cricoid cartilage and the trachea. All ingesta by the mouth passed through the upper wound. On the fifth day, the ligatures separated, and the larynx again retracted. On the sixth, an elastic gum catheter was passed into the inferior cut extremity of the gullet, and through this nutritious fluids were regularly administered. The wound granulated, and filled up in some measure; the patient continued to receive both air and nourishment through tubes introduced downwards from the wound in the throat. Whilst pouring in food, saliva was secreted in the mouth in great profusion. The sense of smelling remained tolerably acute, and he also possessed the power of imperfect whispering articulation.

When, from the untoward circumstances of the case, or from neglect, the opening in the windpipe remains long open, and becomes fistulous, the larynx contracts, and the voice is in a great measure lost, the patient breathes almost entirely by the unnatural opening, and all the respiratory functions are conducted imperfectly. But even this state of parts may admit of remedy, as is exemplified by the following case: Elizabeth Oswald, aged twenty-seven, attempted suicide in 1826, and wounded the larynx through the crico-thyroid ligament. She was under treatment for several months; but was at length abandoned with loss of voice, breathing entirely through a silver tube placed in the original wound. On her applying to me, I found the larynx had contracted; an exceedingly minute aperture, not capable of admitting a common dressing probe, extended from the wound towards the glottis, constituting all that remained of the upper part of the natural air-passage at this point. Small bougies were introduced from the wound into this diminutive canal; and by gradually increasing their size, the passage was brought to its natural diameter in less than three months. Part of the trachea below the wound had also contracted considerably, and was dilated by similar means.

A long œsophagus tube was introduced by the wound into the mouth, there laid hold of and drawn upwards, and then pushed down into the trachea, so that it extended from the mouth to some inches below the wound of the trachea. Its introduction was followed by a severe fit of coughing, which lasted about half an hour. The tube, nine inches long, and equal in diameter to the largest œsophagus tube, was retained in the windpipe for fifteen days, during which it caused great salivation; the teeth loosened, and the strength was extremely reduced.

The callous edges of the wound were removed by incision, and the opening closed by suture. The tube was removed on the tenth day thereafter, and the patient breathed well. Within a few hours, however, respiration became difficult, and tracheotomy (below the isthmus of the thyroid) was performed. A silver tube was introduced into this recent longitudinal opening, and retained for five days, when it was replaced by a smaller one. After twenty days, this tube was also removed, and in a short time afterwards the wound closed completely. The patient continued to breathe with ease through the larynx, and slowly recovered her voice. When agitated, or after sudden and violent exertion, her inspirations are a little longer than natural, but in other respects the cure is complete. She was in very good health some years after the restoration of the air-tube.
