EAST Multicenter Trial on Targeted Temperature Management for Hanging-Induced Cardiac Arrest

BACKGROUND We sought to determine the outcome of suicidal hanging and the impact of targeted temperature management (TTM) on hanging-induced cardiac arrest (CA) through an Eastern Association for the Surgery of Trauma (EAST) multicenter retrospective study. METHODS We analyzed hanging patient data and TTM variables from January 1992 to December 2015. Cerebral performance category (CPC) score of 1 or 2 was considered good neurologic outcome, while CPC of 3 or 4 was considered poor outcome. Classification and Regression Trees (CART) recursive partitioning was used to develop multivariate predictive models for survival and neurological outcome. RESULTS Total of 692 hanging patients from 17 centers were analyzed for this study. Their overall survival rate was 77%, and the CA survival rate was 28.6%. The CA patients had significantly higher severity of illness and worse outcome than the non-CA patients. Of the 175 CA patients who survived to hospital admission, 81 patients (46.3%) received post-cardiac arrest TTM. The unadjusted survival of TTM CA patients (24.7% vs 39.4%, p
