Abstract
War surgery is a specialised branch from the art of general surgery, apart from staging in treatment which is purely military, civilian surgeons, first aider, and nursing staff must know about field therapy because disaster, now, may occur anywhere and at any time. In the first chapter, the principles and pathogenesis of war injuries:
1-Blast wave injuries , they include the air-transmitted and water - transmitted blasts and their physical aspects, the
factors affecting the damaging effect of blast wave, and the pathogenesis Of blast inyury.
2-Bullet injuries, they are divided into low velocity, medium velocity, high velocity and very high velocity, the factors influencing the effect of a missile wound, destructive energy, Yawing, tumbling, precession, nutation and fragmentation, the enterance and exit wound, the type of tissue and contamination.
3-Thermal injuries, including thermal burns and cold injury with its clinical features trench foot and frostbite, the predisposing factors to injury and epidemiology.
4-Crush injury, for patients who have been crushed beneath debris or run over or their limbs compressed for an hour or more.
5- The problem of infection, in war injuries there are devitalization of tissue proteins, disruption of the local blood supply, the introduction of foreign bodies and contamination with variety of bacteria, also oedema and the time lag between wounding and evacuation and surgical interference add other factors to enlarge the problem of infection. The contamination is universal and by more than one species of bacteria. Tetanus and gas gangrene are the most serious types of infection, Bacteriology, clinical pictures, treatment and prophylaxis were discussed. In the second chapter there are :-
1. The management of mass casualty, is carried out in many stages, first aid, first medical aid, qualified medical aid, and definitive care which is carried out in a general hospital staffed and equipped for definitive care. For success, and to carry out the correct procedures at the appropriate time and in the appropriate facility, sorting is important in each stage.
Triage system implies a categorization and distribuation of casualties, communication, and transport. Patient care categories include, minimal care, light medical attention, major medical attention and hopelessly injured category. Evacuation occur by many ways, air evacuation is rapid, but we must take in consideration reduction of the atmospheric pressure, reduction in air density and reduction in oxygen tension.
2.Care of specific disorders, blood volume deficit as it is a major cause of morbidity and mortality, management of infection, staged treatment in mass casualties of burns and cold injuries, first aid and later management and lastly the general lines of the treatment of blast injuries.
3.Priorities of treatment :-
.The first priority is for casualties in asphyxia or shock.
.The second priority is for visceral , vascular and closed cerebral injuries.
.The third priority is for spinal injuries, soft tissues wounds, lesser fractures and dislocations, injurie of the eye and maxillofacial injuries without asphyxia. However, in the management of mass casualties, the initial medical effort must be to save as many lives as possible by restricting this initial effort to the simple-St procedures to the greatest possible number of those likely
to survive and eventually to return to duty. To achieve this, sorting is very important and yet the most difficult duty in military surgery.
