다국어 초록 (Multilingual Abstract)

The prevalence of subarachnoid hemorrhage (SAH) following out-of-hospital cardiac arrest (OHCA) varies between 4 to 18%. The differences of prehospital and laboratory variables between SAH and non-SAH following OHCA were not known. The main objectives of our study were to describe the incidence of SAH occurring after OHCA in Korea and the differences of clinical variables between SAH and non-SAH groups. A retrospective-observational registry-based study was conducted in an emergency department (ED) at the three university hospitals from January 2009 to January 2014. Laboratory variables were examined for a comparison analysis between SAH and non-SAH groups. The total of 2701 patients who had cardiac arrest were registered in our database. Among them, 1131 patients (42%) had return of spontaneous circulation (ROSC) after the advanced cardiac life support (ACLS). After ROSC, brain CT was performed on 836 patients and the existence of SAH was found in 98 patients (12%). Gender and prehospital ROSC were significantly different between SAH and non-SAH (p=0.001 and p=0.006, respectively). The incidence of SAH after ROSC from OHCA was about 12 percent. There were no statistical differences in laboratory findings between SAH and non-SAH.
