Background: The aim of this study was to compare the outcome of severe
blunt trauma in children receiving prehospital care from either physi
cian-staffed advanced life support (ALS) units, or from basic life sup
port (BLS) units staffed by emergency medical technicians. Methods: Th
e records of 288 children with severe blunt trauma who required intens
ive care in the regional level 1 trauma center or who died from their
injuries were analyzed retrospectively. Patients were excluded if resu
scitation at the scene was not attempted, if the level of prehospital
care was unspecified, or if arrival at the level 1 trauma center was d
elayed beyond 150 minutes. Seventy-two patients met the inclusion crit
eria of BLS-, and 49 the criteria of ALS-prehospital care. Results: A
reduced mortality rate (22.4% v 31.9%) was seen in the ALS group, whic
h was more apparent in a ''salvageable but high-risk'' subgroup, chara
cterized by Glasgow Coma of Scale 4 through 8, Pediatric Trauma Score
of 0 through 5, and Injury Severity Score (ISS) of 25 through 49. Howe
ver, a statistically significant difference was only seen when trauma
severity was evaluated by the ISS. Conclusion: An improved outcome in
children with severe blunt trauma has been demonstrated when prehospit
al care is provided by physician-staffed ALS units compared with BLS u
nits. Copyright (C) 1998 by W.B. Saunders Company.
