Saczkowski et al reported a simple score for evaluating a patient with accidental hypothermia who requires extracorporeal life support. This can help to identify a patient who may benefit from more aggressive management. The authors are from Kelowna General Hospital and University of British Columbia.
ICE = International Accidental Hypothermia Extracorporeal Life Support
Parameters:
(1) sex
