Induction techniques that reduce redistribution hypothermia: A prospective, randomized, controlled, single blind effectiveness study [post]

2019 unpublished
BACKGROUND While much effort has been devoted to correcting intraoperative hypothermia, less attention has been directed to preventing redistribution hypothermia. In this study, we compared three different anesthetic induction techniques to standard IV propofol inductions (control) in their effect on reducing redistribution hypothermia. METHODS Elective, afebrile patients, age 18 to 55 years, were randomly assigned to one of four groups (n=50 each). Group "INH/100" was induced with 8%

Patients were maintained with sevoflurane in 50% nitrous oxide and 50% oxygen in addition to opioid narcotic. Forced air warming was used. Core temperatures were recorded every 15 minutes after induction for one hour. RESULTS
