Effective factors on thorax and abdomen stab wounds patients' mortality

Stab wounds are important causes of mortality and morbidity in our country as it hasbeen all over the world. We planned this study in order to determine the effective factors onmortality on the patients exposed to stab wounds of thorax and abdomen.We retrospectively reviewed the hospital records of 660 patients admitted to EmergencyDepartment of Dicle University, between February 2003 and July 2006. In our study; 97.7%(n=645) of the patients were alive, while 2.3% (n=15) died. The mean age was 24.21±10.8(4?72) years (634 male-26 female). The most frequently injured region of the body was thorax,most frequently injuries were single injuries, the most frequent extra organ injury as to theupper extremity in stab wounds. Most of the patients were followed and treated in emergencydepartment. The data in our study was evaluated with univariety analysis. We found that mostfrequent injury age in our patients was 11-30 and included younger adults (P=0.000). Most ofthe patients were admitted to our department in spring and summer (P=0.000). Mostfrequently, injuries were caused of violence (P=0.000). Most frequently used instruments wereincisive and perforating instruments (P=0.000). The injuries were more common between12:00?24:00 hours (P=0.000).In univariety analysis we found lung injury (P=0.003), tube thoracostomy output morethen 1500 cc (P=0.000), emergency thoracotomy (P=0.000), cardiac injury (P=0.000),pericardial effusion (P=0.000), left ventricular injuries (P=0.000), thoracic great vessel injury(P=0.000), small bowel injuries (P=0.002), injuries of colon (P=0.000), renal injury (P=0.020),injuries of pancreas (P=0.000), existence of retroperitoneal hematomas (P=0.009),intraabdominal hemorrhagea more then 2000 cc (P=0.000) and abdominal great vessel injury(P=0.000) were the factors that were predictive on mortality in injury of thorax and abdomen.Our study showed that delayed admission time (P=0.001), delayed operation time(P=0.02), GCS 3-7 (P=0.000), GCS 8-12 (P=0.04), serious anemia during admission(P=0.000), existence of shock on admission (P=0.000), multiple blood transfusion (P=0.000),ISS ³ 25 (P=0.000), PATI ³ 25 (P=0.000) and low RTS (P=0.000) were found to besignificant factors in predicting mortality.Delayed operation time (P=0.02), existence of shock on admission (P=0.000), PATI³ 25 (P=0.000), GCS 3?7 (P=0.000), GCS 8?12 (P=0.04) and ISS ³ 25 (P=0.000) found inunivariety analysis were analised with multivariety analysis by using Logistic Regression(Backward Stepwise Wald) method.Multivariate analysis showed that existence of shock during admission is the parameterthat can be used in predicting the mortality of patients (OR=0.106, CI=0.012?0.902, P=0.040).
