[Biomechanico-clinical study of gunshot wounds (general problems--II)].

Whenever the surgeon finds himself face to face with a wound (probably this is the only opportunity for a meeting between physician and pathology which seems to be able to leave the "illness" on one side, almost forgotten, as it were), even when immersed in routine, he can hardly help making a number of considerations of a general nature, to which the sentence above in brackets is not entirely extraneous. In practice, we cannot help asking ourselves an apparently simple, almost banal, question: what exactly is trauma? This triggers off a whole series of secondary queries, such as, for instance, what the relationship is between trauma and classical pathology? In the first place, it should be pointed out that "traumatic" pathology is undoubtedly the only instance of pathology in which, as a rule, at least at the outset, one can justifiably talk about the "isolated" role of what can certainly be regarded as an out-of-body factor. If, then, we consider the specifically morphological and pathophysiological aspects of the period subsequent to the traumatic insult, we find ourselves in an even more embarrassing position: we are faced with irreparably devastated organ and body structures, or with a situation which is already on the way to convalescence. One last alternative is that the traumatic insult is merely a memory, a key finding in the case history, a past reality which to all intent and purposes has ceased to exist, and we are faced with extremely complex clinical pictures which we tend to label as complications. A few examples by way of explanation: shock, adult respiratory distress syndrome (ARDS), stress ulcer, acute post-traumatic cholecystitis, haemorrhagic pancreatitis, and problems caused by resolving the hypovolaemia-ischaemia situation and by implementing reperfusion (oxygen radicals). Trauma favours - and surgeons concerned with organ transplants are well aware of this - the only possibility of death which, perhaps with a grain of excessive optimism, we may even accept as fruitful, in that it occurs without all the destructive deterioration involved in the process of dying. The above consideration probably plays a major role in our attitudes of almost fatalistic resignation towards the youthful victims of trauma.(ABSTRACT TRUNCATED AT 400 WORDS)
