Prevention of hypothermia during orthotopic liver transplantation: comparison of three different intraoperative warming methods

Abstract

Hypothermia is a frequent and sometimes clinically important problem during orthotopic liver transplantation. Numerous methods have been suggested to reduce intraoperative heat loss and promote active warming. In this study we compared an electric under mattress, a warm air under mattress and a forced warm air convective heating blanket. The forced air convective warming system was shown to produce significantly higher patient temperatures than the two other systems.
