OF HOSPITAL OR CONTAGIOUS GANGRENE, AND SLOUGHING PHAGÆDENA.

This disease has been long known, and has proved very fatal in crowded and badly-aired hospitals. It may break out at any season, but hot, sultry, and damp weather is most favourable to it. No breach of surface, however small, is secure from its attack. The wound becomes painful and swollen, and loses its healthy, florid appearance; the granulations are flabby, and appear as if distended with air; vesicles form, containing serum or a bloody fluid; the pain is stinging; the secretions are suspended; and the wound is either altogether dry, or covered with slimy, tenacious, and peculiarly offensive matter. An ichorous discharge follows, the pain increases. The sore assumes a circular form, and its edges are everted; erysipelas attacks the surrounding integuments, often extending over the whole limb, and forming a principal feature of the disease. In fact, violent erysipelas and hospital gangrene are affections very closely allied to each other, often arising at the same time, and from the same causes. Both are accompanied with great constitutional disturbance; but in erysipelas, this generally precedes, whilst in hospital gangrene, it follows, the appearance of the malady. The lymphatic glands, in the neighbourhood of the gangrenous part, inflame and suppurate, the skin gives way, and the gangrene soon seizes the newly-formed sore. Fever supervenes, the pulse is often full and strong, and the surface hot; there is great nausea and thirst; the tongue is brown, and the bowels much disordered. The inflammation and ichorous discharge increase. A thick slough covers the sore, and its fetor is peculiar and intolerable. The burning pain is excruciating. Blood oozes out, and, in the last stage, the hemorrhage is often copious from large vessels exposed by the ravages of the disease.

Now, extensive mortification occurs, the strength fails, the pulse becomes tremulous and indistinct, the features collapse, the surface is bedewed with a cold sweat, diarrhœa and hiccough come on, and death puts an end to the patient’s suffering. Such is the progress of the disease in those who were previously in perfect health. Often, however, it is attended with typhoid symptoms almost from the beginning, in people whose constitutions are wasted, who have long laboured under disease, or who have been long confined in hospital. The important distinction between these cases must influence the treatment; what succeeds in the one will destroy in the other. It is not the name of the disease which is to be combated, but each symptom as soon as it presents itself.

Those who have been once afflicted with hospital gangrene are extremely liable to its recurrence, and that too on the same sore; though the secondary disease is much less acute. This form has been termed Sloughing Phagædena, and may seize a sore not previously affected with gangrene. The wound, recovering from the first attack, and appearing to heal rapidly, with good discharge and healthy surface, presents, near its edge, a small dark spot or ulceration, of the size of a small bead or shot, of a circular form, with a ragged edge, excavated surface, and fetid discharge. Several such points may appear; they spread rapidly, unite, and the surface is soon destroyed. It is not uncommon to find one part of the sore of a healthy appearance, and even cicatrising, whilst in another part the surface is rapidly disappearing. The patient complains of a burning sensation in the part; suppuration occurs round the edges and beneath the slough, and the dead parts separate; but the same process again takes place, and another slough forms. The malady proceeds often with a rapid and alarming pace; the sloughs are soft, pulpy, and reddish, and separate one after another, exposing muscles, nerves, bloodvessels, and bones. Joints are opened into, and the vessels, having been exposed, perhaps for a day or two, give way, and fatal hemorrhage ensues, their cavities not being obstructed with coagula as in sphacelus. The patient is sick, has no appetite, and labours under other symptoms of deranged stomach; there is restlessness, with a small quick pulse, and all the symptoms of a weakened and sinking system. The ulceration becomes more rapid, the discharge is bloody and peculiarly offensive; all the symptoms increase in violence, and may proceed for fifteen or twenty days, or terminate in four or five, either in convalescence or death.

Hospital gangrene is supposed to arise from a variety of causes: from the state of the atmosphere, moist and hot—from inattention to cleanliness, the parts around the sore being seldom wiped, the matter collecting amongst the dressings, and becoming acrid by putrescence—from irritating applications, as rancid ointments—from a too stimulating diet, and from the abuse of wine and spirits—from mechanical irritation, in moving the wounded over rough roads and in bad conveyances, as after great engagements—from specific contagion without immediate contact. After being once generated, it is propagated by direct communication, by the application of morbific matter from sponges, dressings, or instruments. It is not easy to say how the disease originates.

In the treatment of this scourge, great attention must be paid to cleanliness in all circumstances. Free ventilation must be constantly preserved in the apartments of the sick, and fumigations assiduously employed. The infected ought to be separated from the others, and but few patients placed in the same ward. Stagnant drains and accumulations of filth out of doors are to be removed; otherwise, during hot weather, the atmosphere becomes much vitiated. Care must be taken, also, to destroy all the dressings which have been used; not to employ sponges, but to wipe the surface in the neighbourhood of the sore occasionally with tow, which is to be burnt immediately, being an article of little value, and easily procured. Too much attention cannot be paid to the cleaning of those instruments with which gangrenous sores have been treated, before they be applied to healthy wounds. As to the constitutional treatment, the alimentary canal must first be purged of its solid contents, and the secretions afterwards kept in as good a condition as possible. When the wound or sore is surrounded with intense inflammation, and when the skin is dry and the pulse strong and full, with all the other symptoms of an inflammatory diathesis, immediate recourse must be had to free abstraction of blood from the system, as thus only can the progress of the disease be efficiently arrested; and if inflammatory symptoms exist, when there is reason to expect the occurrence of the disease, though no symptom of it has yet appeared, then, too, venesection combined with purgatives is demanded, as being the most powerful preventives. Emetics are also recommended. When the affection is from its commencement accompanied with typhoid symptoms, depleting measures must do irreparable mischief: in such cases, the local pain and irritation will be relieved by the exhibition of opium or camphor, and it may also be of service to preserve a perspirable state of the surface by means of Dover’s powder, or other diaphoretics. Preparations of Peruvian bark, the decoction with or without the tincture and acid, or the sulphate of quina, are often given with great advantage—opium is also usefully exhibited. Vinegar, weak acids, the nitric and muriatic acids diluted, have been used as external applications, and nitrate of silver, the red oxide of mercury, and the actual cautery, have been applied with the view of removing the diseased parts, and procuring a healthy surface. Arsenic in solution, used so as to produce a slough, followed by hot dressings, has been supposed to be serviceable. A much safer and more powerful application is the strong nitric acid, which sometimes requires to be applied over the diseased surface very freely, and repeated if need be.
