Prehospital Extrication Techniques: Neurological Outcomes Associated with the Rapid Extrication Method and the Kendrick Extrication Device

Abstract

Most emergency medical service personnel rely on one of two techniques to extricate motor vehicle crash victims; the Rapid Extrication Maneuver (REM) or the Kendrick Extrication Device (KED). The purpose of this study was to compare pre- and postextrication neurological outcomes between these two techniques. A retrospective review was conducted of all adult patients with a vertebral column injury resulting from motor vehicle collision and admitted to a Level I trauma center between January 1, 2003 and December 31, 2010. Standardized pre- and postextrication neurological examinations were reviewed for all patients. More than half of patients (N = 81) were extricated using the KED (53.1%, n = 43) and 46.9 per cent (n = 38) were extricated with the REM. Except for the thoracic Abbreviated Injury Score, no differences between groups emerged related to the Glasgow Coma Scale score, Injury Severity Score or Abbreviated Injury Score. There were no pre- and postextrication changes for motor to all extremities and sensation to all extremities using either method. The results of this study suggest that the REM and the KED are equivalent in protecting the patient from neurologic injury after motor vehicle collision.
