The results of prolonged and extensive procedures in the critically injured are poor, even in experienced hands. The operating theatre is a hostile and physiologically unfavourable environment for the severely injured patient. Laparotomy for major trauma involves dissipation of heat and massive blood loss requiring replacement. The result is a vicious cycle of hypothermia, acidosis and coagulopathy leading to death from an irreversible physiological insult (62). The damage control concept places surgery as an integral part of the resuscitative process, rather than an end in itself, and recognises that outcomes after major trauma are determined by the physiological limits of the patient, rather than by efforts of anatomical restoration by the surgeon. All those involved in the care of wounded patients should be familiar with this concept and its surgical and logistical implications.

Findings on physical examination are not good predictors of vascular injury in stable patients with gunshot wounds to the neck. Our findings question the validity of physical examination alone, as a safe and accurate assessment of patients with gunshot wounds to the neck. Arteriography or ultrasonography is needed to identify vascular injuries.

A major limb amputation (i.e. proximal to carpals and tarsals) is a common surgical procedure in war. Since more than 50% of casualties treated in a conflict are likely to have wounds to the extremities, 1 it is inevitable that a proportion of these limbs will be amputated.After 3 years of conflict in World War I, 300,000 amputations had been carried out Conclusions:In presenting our amputation rate of 16%, we highlight the lack of uniformity in describing 'amputation rates' between conflicts. A consistent method for quantifying amputations performed in a conflict setting could prove to be a useful tool.

Penetrating trauma is on the increase as a result of interpersonal violence throughout the world. It is essential that military surgeons are familiar with such injuries and trained not only in the principles of their management, but also have first-hand operative experience before deployment in the field of conflict. More often than not, this experience is to be gained in the civilian urban setting in countries such as South Africa and the USA.The article addresses the first requirement -the principles of managementand outlines basic measures to enable those unfamiliar with penetrating wounds of the torso to make a reasonable and directed approach to dealing with these patients. It does not attempt to give definitive advice on specific injuries.It is organised according to anatomical regions, but emphasises that this is only in order to put shape to the article; penetrating injuries frequently having no respect for anatomical boundaries. Particular attention is drawn to difficult areas such as mediastinal injuries, and to modern concepts of 'damage control' surgery and the 'abdominal compartment syndrome'. The emphasis throughout is on how to get out of trouble and where particular danger spots may be anticipated. Reference will be made to the differences that may be expected within the military environment as opposed to the civilian setting, where rapid and (usually) safe evacuation to a well-equipped secure facility may not be possible.The article aims to raise the awareness of those involved in the care of patients with penetrating wounds of the torso that a methodical approach with a practised team of experienced individuals can salvage injuries which at first sight may seem terrifying or hopeless.
