Pediatric blunt trauma: a retrospective analysis in a Level I trauma center.

This study consisted of an 8-year retrospective trauma registry analysis of blunt trauma and comprised of 2458 children (<18 years of age) and 4568 adults (18-64 years of age). Falls and motor vehicular crashes were seen in 30.4 per cent (749) and 23 per cent (566) of children, and 25.4 per cent (1158) and 41.9 per cent (1914) of adults. Children had a higher mean revised trauma score (7.69 vs 7.66) and Glasgow Coma Score (14.5 vs 14.3), and a lower Injury Severity Score (ISS; 6.68 vs 7.83 and hospital length of stay (2.8 vs 3.8 days) with P < 0.05. Overall mortality was 1.3 per cent in children and 1.9 per cent in adults (P = 0.05). Pedestrian accidents resulted in a 3.8 per cent (6/161) mortality rate. Pediatric nonsurvivors had a 6.4-fold higher ISS than survivors compared with a 5.2-fold increase in adults. Mortality progressively increased with higher ISS; 0.09 per cent in <15, 1.3 per cent, in 15 to 24, and 17 per cent in children with > or = 25 ISS. Mortality in multiple chest injuries was 19 per cent. The presence of chest trauma resulted in a 46-fold higher mortality in children. Most lethal injuries were combined head, chest, and abdomen trauma with a 25 per cent mortality in children and 28 per cent in adults. Admission Glasgow Coma Score <9 and systolic blood pressure below 100 mm Hg carried high mortality: 39 and 6 per cent in children vs 31 and 24 per cent in adults. Ninety-seven per cent of children and 89 per cent of adults were discharged home.
