321 Severe Metabolic Acidosis Was Associated With Unfavorable Neurological Outcome in Patients With Out-of-Hospital Cardiac Arrest

Metabolic acidosis is observed in 98% of patients with Out-of-hospital cardiac arrest (OHCA). The longer the no-flow or low-flow duration, the more severe the acidosis is in these patients. This study aim to demonstrate the blood pH on arrival at emergency department (ED) could be an independent predictor of neurological prognosis in patients with OHCA.
