1. Cortical spreading depolarizations are a novel mechanism independently associated with unfavorable clinical outcome in TBI Jed Hartings, PhD Department of Neurosurgery University of Cincinnati [email_address] 513-558-3567 COSBID
12. Results No differences in recording durations (p>0.50), timing of surgery (p>0.50), or prognostic scores (p=0.34). Significant difference in outcome between depolarization categories Ο 2 , p<0.01 Poor outcome (dead, VS, severe disability) ISD CSD None Poor outcome More likely Less likely Prognostic scores
