The Value of Injury Severity Score and Abbreviated Injury Scale in the Management of Traumatic Injuries of Parenchymal Abdominal Organs

Abstract

The aim of this study was to investigate the influence of etiology, types of injury, levels of consciousness and the Injury Severity Score (ISS) and Abbreviated Injury Scale (AIS) values on the selection of treatment modality and survival in patients with injuries of parenchymal abdominal organs. Case records of 224 patients treated for traumatic injury of parenchymal abdominal organs from January 2003 until December 2015 were reviewed. Th e values of ISS and AIS of injury severity were calculated and compared to the values obtained according to the etiology, state of consciousness and survival. Of the 224 patients, 172 (76.8%) were treated by surgical approach and 52 (23.2%) were treated conservatively. Th e mean patient age was 40.1}18.3 years. Th ere were 97 (43.3%) polytrauma cases. Of the 224 injured patients, 143 (63.8%) were treated with transfusions of blood products. Two hundred and six (92%) patients survived. Th e mean AIS and ISS values were significantly lower in patients that survived (AIS=3; ISS=28) than in those that died (AIS=5; ISS=34) (p< 0.001). There was a statistically significant difference in AIS and ISS values between conscious (AIS=2.7; ISS=25.9) and unconscious (AIS=3.2; ISS=33) patients (p< 0.001). Of the 224 patients that did not survive, 18 (8%) were hemodynamically unstable. Survival depended on hemodynamic stability at admission; the ISS and AIS values were associated with the injuries and state of consciousness at admission. Hemodynamic stability, state of consciousness, and ISS and AIS values were the quality predictors of survival after abdominal traumatic injury.
