The Effect of Brain Hemorrhage on the Prognosis of Out-of-Hospital Cardiac Arrest: a Retrospective Study

ABSTRACT

PURPOSE: Spontaneous intracranial hemorrhage (ICH) is not an uncommon cause of cardiac arrest. The purpose of this study was to identify the prognosis of patients with ICH for Out-of-Hospital Cardiac arrest (OHCA). METHODS: From January 2008 to December 2010, a total of 214 patients were checked brain computed tomography (CT) in OHCA. The majority of patients were male (136, 63.8%), and the median age was 55.0 (+/-16.7). We included all patients who were checked through brain CT for non-traumatic OHCA. Data were collected from electronic medical records and pre-hospital records. Demographic, clinical and laboratory data were compared between the ICH and non-ICH group. RESULTS: The detection of ICH by clinical manifestations and laboratory data was difficult. Out of 214 patients, 21 (9.8%) patients were positive for ICH and 193(90.2%) patients had a normal brain CT. In demographic and clinical data, the neurological outcome (CPC score, p=0.009) and 30-day survival rate (p<0.001) were statistically different between the two groups. Using the Cox proportional hazards model, the ICH group had a 3.54 hazard ratio compared with non-ICH group. In addition, pH (p=0.033), lactate (p=0.023) in ABGA, potassium (p=0.008), glucose (p=0.026), and S-100 (p=0.047) showed significant results. CONCLUSION: The prognosis of ICH patients in OHCA is poor; further studies are needed to improve the prognosis of ICH patients after ROSC in OHCA.
