616: SAH

Abstract

Introduction: Subarachnoid Hemorrhage is one of the most debilitating forms of stroke. In the last 20-30 years, the management of SAH has evolved to include endovascular treatments, "triple H therapy", and multi-modal monitoring. We reviewed the epidemiology and outcomes of our SAH population. Methods: This is a descriptive retrospective database review of patients with SAH. Patients presented over a 2-year period from 2009-2011 at a large academic institution. Patient data was collected in six general categories. Demographics, Outcome status, Chronic Health Information, Severity of Illness, In-patient therapies, and Acute in patient diagnoses are reported. Results: There were a total of 451 patients. 59% female, mean age was 55 ± 14. Fifty 0ne percent white, 18% Black, 17% Hispanic, and 13% other, mean GCS was 11 ± 5, 40% had a history of HTN, 15.1% Diabetics, 52% on mechanical ventilation with 13.5% developing ALI during hospital course. 65.2 percent presented with a Hunt and Hess Grade 3 or higher at 23.4%, 19.3%, and 22.5% for grades 3, 4, and 5 respectively. Mortality was 21.5% of which 50% died within 48h of presentation. 68.6% and 24.5% of patients with Hunt and Hess Grade 4 or 5 survived Conclusions: Patients with Subarachnoid hemorrhage appear different from other stroke patients. Overall Mortality for grade 4 and 5 SAH patients is lower than previously reported. Of those who die, mortality within 48 hours is 50%. There is limited data on prevalence of ALI and mechanical ventilation in SAH, interestingly, mechanical ventilation and ALI occur with significant frequency.
