BACKGROUND: It was reported that pediatric trauma score (PTS) is an important tool for the initial assesment of injury severity and could help in the triage of injured children as well. The aim of this study is to investigate the prognostic value of PTS in blunt abdominal traumas. METHODS: Between 1997 and 2003, children with blunt abdominal trauma who treated in the Department of Pediatric Surgery, Trakya University Medical Faculty were evaluated with retrospective analysis. PTS was resignated for each case. Individual morbidity and mortality were correlated with PTS. Data analysis were performed with Mann Whitney U test and ROC curve statistically. RESULTS: Seventy five patients were included in this study. The mean age of children was 7.5±4.2 years (10 months-15 years). Mechanisms of injury were as follows: automobile versus pedestrian 30, falls 18, motor vehicle crashes 14, bicycle accidents 7 and others 6. Forty two abdominal organ injuries were found.. PTS of the patients who had abdominal injuries were different statistically from others (p<0.05). On the ROC curve sensitivity and specificity were found as %74 and %12 respectively in those with PTS scores of 8. CONCLUSION: PTS was found to be of low sensitivity and specificity for blunt abdominal trauma patients.
