Abstract P201: Rapid Liquid Surface Cooling in Comatose Patients with Cardiopulmonary Arrest Improves Survival
Introduction: Cardiopulmonary arrest (CPA) causes >400,000 deaths/year in the US. Few patients (pts) with return of spontaneous circulation survive to hospital discharge. Therapeutic hypothermia (TH) decreases mortality and reduces neurologic impairment. Hypothesis: Rapid induction of TH improves survival.
Methods: TH using the ThermoSuit System (TSS) (Life Recovery Systems, Kennelon, NJ) was instituted at Ochsner Medical Center in March 2008. All pts undergoing TH (32–34°C, 24 hours) for CPA with TSS were reviewed. Primary outcome was survival to hospital discharge. Secondary outcome was functional status at follow up.
Results: In 15 CPA pts treated, 100% of the 6 with VT/VF survived to hospital discharge. Neurological outcome at 60 days for the VT/VF pts was excellent. Treatment time to 34.5°C was 35 min (9–90 min) with an average cooling speed of 3.3°C/h (2.4–5.4°C/h). After cooling 7/15 pts (47%) underwent coronary angiography; 1 required coronary intervention.
Conclusion: TH using TSS is faster and better than historical controls regardless of the CPA etiology. It benefits VT/VF CPA pts most.
