Epidemiologic aspects of pediatric multiple trauma in a Spanish urban population.

BACKGROUND/PURPOSE: Trauma is still the most frequent cause of mortality and disability in childhood and adolescence. An epidemiologic prospective study on children under 16 years of age with multiple trauma (MT) was conducted in a large Spanish urban university hospital over a 6-year period.

METHODS

Of 1,937 children admitted at the pediatric trauma unit for musculoskeletal injuries from March 1988 until March 1994, 56 patients including 37 boys and 19 girls had MT. MT was considered when at least 2 long bones were fractured or there was a fracture of 1 long bone combined with an injury of 4 other major anatomic regions (face and neck, thorax, abdomen, or neural system). The severity of injuries was evaluated according to the modified injury severity score (MISS).

RESULTS

Injury to pedestrians was the most frequent cause of MT (54%). The overall mortality rate of the series, including those children dying during transport to the hospital was 11.5%. The average MISS for the whole group was 15 (range, 5 to 59). Head trauma was the most frequent associated injury (52%), two thirds of which were considered minor injuries (Glasgow Coma Scale >15). Seventy-seven fractures were registered, 10% of which were open fractures. External fixation was the most common surgical technique among operated fractures. The average hospitalization period was 16 (median, 13; range, 1 to 150) days. Children with a MISS above 18 points showed a significant longer hospitalization period (mean, 31 +/- 45 days) as compared with those with MISS below 18 points (mean, 10 +/- 7 days; P < .05). There was a strong correlation between the MISS and both the period of hospitalization at the pediatric intensive care unit and the total length of hospital stay.

CONCLUSIONS

Pedestrian accidents caused by motor vehicles in children playing at the street contributed most significantly to MT in the urban pediatric population. Special care for prevention must be taken in the age group of 6 to 10 years. Head injury was the main cause of death in children with multiple trauma. MISS was found to be a good predictor of survival and duration of hospital stay in pediatric MT.
