St-Louis et al reported the Pediatric Resuscitation and Trauma Outcome (PRESTO) model for evaluating pediatric trauma patients. The authors are from McGill University in Montreal.
Patient selection: pediatric trauma from 0 to 14 years
Parameters:
(1) age group
(2) hypotension
(3) pulse
(4) AVPU
(5) oxygen saturation in percent
(6) airway support (supplemental oxgen)
(7) interaction for age and pulse
