Extracorporeal Cardiopulmonary Resuscitation with Therapeutic Hypothermia for Prolonged Refractory In-hospital Cardiac Arrest

ABSTRACT

BACKGROUND AND OBJECTIVES: We identified the impact of extracorporeal cardiopulmonary resuscitation (ECPR) followed by therapeutic hypothermia on survival and neurologic outcome in patients with prolonged refractory in-hospital cardiac arrest (IHCA). METHODS: We enrolled 16 adult patients who underwent ECPR followed by therapeutic hypothermia between July 2011 and December 2015, for IHCA. Survival at discharge and cerebral performance category (CPC) scale were evaluated. RESULTS: All patients received bystander cardiopulmonary resuscitation (CPR); the mean CPR time was 66.5±29.9 minutes, and the minimum value was 39 minutes. Eight patients (50%) were discharged alive with favorable neurologic outcomes (CPC 1–2). The mean follow-up duration was 20.1±24.3 months, and most deaths occurred within 21 days after ECPR; thereafter, no deaths occurred within one year after the procedure. CONCLUSION: ECPR followed by therapeutic hypothermia could be considered in prolonged refractory IHCA if bystander-initiated conventional CPR is performed.
