[Effect of amino acid solution on intraoperative core temperature the influence of anesthetics].

Background: Propofol anesthesia has more thermogenic effect than isoflurane when combined with amino acid solutions. The purpose of this study is to compare the effects of intraoperative administration of amino acid solutions on intraoperative core temperature under propofol anesthesia with those under sevoflurane anesthesia.

Methods: Thirty patients scheduled for total hip arthroplasty were randomly allocated to undergo either propofol anesthesia or sevoflurane anesthesia.

[Changes in core temperature associated with lower extremity tourniquet--the influence of ambient temperature and warming equipments].

Background: We investigated changes in core temperature associated with lower extremity tourniquet (TQ) under two different ambient temperatures (1) and two different warming equipments (2) under general anesthesia combined with lumbar epidural anesthesia.

Methods: (1) The values of core temperature at ambient temperature of either 22 degrees C (n = 15) or 20 degrees C (n=15) were recorded after induction of anesthesia, at start of TQ application, at the termination of TQ application, and 14 minute after TQ release. (2) The values of core temperature using either air-forced warming or active heated i.
