[The causes of death and risk factors in patients of war wound and trauma of extremities by logistic regression model].
OBJECTIVE
To explore the causes of death and risk factors in patients of war wound and trauma of extremities.


METHODS
This retrospective study involved 352 patients of war wound and trauma of extremities admitted to 303rd Hospital of People's Liberation Army during the period between 1968 to 2002. All the data were reviewed and the causes of death of 15 patients were analyzed by autopsy, and a computer's logistic regression model analysis was performed to approach the risk factors of death.


RESULTS
Fifteen of the three hundred and fifty-two patients were died (4.3 %). The causes of death included acute renal failure (ARF) (46.7%, 7/15), lung embolism (20.0%, 3/15), clostridial myonecrosis (20.0%, 3/15) and multiple organ system failure (MOSF) (13.3%, 2/15). In the univariate analysis, the risk of death increased by shock, time admitted to hospital, amputation, time of tourniquet, associated injury of head, thoracic region, abdomen or blood vessel (P < 0. 05). In the logistic regression model analysis, shock and amputation were the two factors most strongly associated with the death of patients of war wound and trauma. (P < 0. 05).


CONCLUSIONS
Acute renal failure (ARF) was the main cause of death of patients of war wound and trauma of extremities. Its should be helpful for minimize the mortality of patients of war wound and trauma to manage the shock in time and have a correct choice of amputation promptly.
