As a rule the wounds themselves need no interference, but in some instances either the exit or entrance wounds may be in undesirable positions for purposes of asepsis, when a large opening may seem safer closed and actually sealed. I saw this method tried in a few cases, but without much success. It is one which might be of much use in Base hospitals if the patients were brought directly into them, but in the Field hospitals, in face of the rush with which the first dressings have to be done, I think it is seldom applicable, and consider the interference with the wound as rather likely to increase the danger of infection than to decrease it.
Dressings should not be too frequent; two should suffice for simple wounds with type forms of entry and exit; there is little discharge and usually no bleeding: hence the more the dry scab form of healing can be simulated the better. When a dressing needs changing from fouling of its outer parts, it is preferable to cut round the adherent part of the deep layers and apply some fresh gauze over the central scab rather than to remove it. One point should be kept in mind: the first dressing in the Field hospital seals the fate of the wound as to the chances of primary union, and hence too much care is impossible with it.
Operations in the Field hospitals were proportionately not numerous, and they should be kept down in number, as far as possible. At the same time such operations as are necessary are mostly of capital importance, such as the treatment of fractures of the skull, abdominal section, the ligature of arteries, and amputations. Of these only the first and last classes occur with any degree of frequency. In order to be prepared for these a stock of filtered water which has been boiled, and some special sterilised sponges, should be at hand if possible, also some small towels which can be wrung out in antiseptic lotion. If sterilised sponges are not to be had, wool pads wrung out in carbolic lotion must be substituted.
Primary amputations bore transport badly. I saw few sent down from the front within a few days of their performance in which the flaps did not slough, or worse consequences ensue. On the other hand, if the first fortnight could be tided over at the front, they did well enough. The head cases on the other hand bore movement fairly well, provided only that asepsis was ensured.
Retained bullets are rarely suitable for removal in the rush of the first work of a Field hospital after an engagement. A short delay is of no importance, and ensures their being removed safely if necessary. With regard to the broad question of the advisability of removing them at all, it may be laid down that they should not be interfered with unless some obvious reason exists. Those most commonly calling for removal are as follows: 1. Bullets lying immediately beneath the skin or quite superficially in any region, or those which, although they have produced an exit opening, yet lie within the body. 2. Those which lie at the bottom of an infected track, or cause secondary suppuration. 3. Those causing pressure on important structures, particularly nerves. 4. Those which interfere with the movements of joints when lodged in the bones or soft tissues in close proximity, or those which lie within the articular cavity itself. Bullets sunk in the great body cavities or in positions difficult of access should never be interfered with. Retained bullets sometimes give rise to unexpected surprises; thus in a man with a retained bullet in the pelvis no steps for its removal were taken. During the man's voyage home on a transport he had an attack of retention of urine. As a catheter would not pass, he was placed in a warm bath, and shortly after passed a Mauser bullet per urethram, and thus saved himself a cystotomy.
One word may be added as to the treatment of shock when severe. Quiet in the supine position, and the administration of a small amount of stimulant, was usually all that was required. Hypodermic injections of strychnine sulph. grs. 1/30 to 1/10 were useful, and in some severe cases, especially where operations were needed, saline infusions with a small amount of stimulant were made into the veins, either at the elbow, or in amputation cases into one of the large veins exposed.
The treatment of hæmorrhage is dealt with in Chapter IV.
The after treatment of simple wounds needs little comment, but bearing in mind what has been said as to the definite healing of the internal portion of the tracks, it will be obvious that in parts such as the thigh or calf, care was needed as to not commencing active work at too early a date. On the other hand, a too long period of absolute rest is also to be deprecated. The best results were obtained by careful movement and massage, commenced after the first week or ten days, according to the appearance presented by the external wound, followed by a gradual resumption of active movement. It was a striking fact that some of the patients suffering from such wounds took longer to become apparently well than many of those who had suffered visceral injuries.
