Multicenter Study
Incidence and clinical features of intracranial hemorrhage causing out-of-hospital cardiac arrest: a multicenter retrospective study.
The general incidence of intracranial hemorrhage (ICH) as a cause of out-of-hospital cardiac arrest (OHCA) remains unclear, although the incidence of subarachnoid hemorrhage has been determined to be 4% to 18%. The main objectives of our study were to describe the incidence of ICH in OHCA and the different laboratory findings between ICH and non-ICH groups. ⋯ OHCA patients with confirmed ICH were identified in about 11% of cases after return of spontaneous circulation. Gender, age, higher glucose, and lower potassium and Po2 levels during CPR were associated with ICH.
