title: Predetermining value analysis of the prehospital phase procedures in trauma victims survival.
abstract: The aim of this study was to analyze the determining value of the procedures carried out during prehospital care in the survival time of traffic accident victims. Data of 175 victims with Revised Trauma Score pound 11, cared for and transported by advanced life support to tertiary referral hospitals, were submitted to Kaplan-Meier Survival Analysis and to Cox proportional hazards model. Four procedure groups associated with survival were identified: basic circulatory; advanced respiratory; volume replaced and medication. Until hospital discharge, the victims who underwent orotracheal intubation and chest compressions showed 3.6 and 6.4 times higher death hazards, respectively. The need for definitive airway and cardiopulmonary resuscitation in the prehospital phase was predetermining with higher death hazard. The less than 1000 ml intravenous fluid replacement was the only predetermining factor with protective power against death hazard.
