Randomized Controlled Trial
Effect of preoperative warming on intraoperative hypothermia: a randomized-controlled trial.
The purpose of this study was to evaluate the effects of preoperative forced-air warming on intraoperative hypothermia. ⋯ A minimum of 30 min of preoperative forced-air convective warming decreased the overall intraoperative hypothermic exposure. While redistribution hypothermia still occurs despite pre- and intraoperative forced-air warming, their combined application results in greater preservation of intraoperative normothermia compared with intraoperative forced-air warming alone.
