title: [Effect of amino acid solution on intraoperative core temperature the influence of anesthetics].
abstract: 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. i.v. amino acid infusion started at anesthesia induction in all patients. The values of tympanic temperature were recorded after induction, during surgery and at extubation.
  
  
  RESULTS
  Patients in the two groups were comparable with their characteristics and anesthetic managements. The temperatures under sevoflurane anesthesia were unchanged during study, whereas those under propofol anesthesia decreased significantly.
  
  
  CONCLUSIONS
  Sevoflurane anesthesia has more preventive effect on intraoperative hypothermia than propofol anesthesia when combined with amino acid solutions.
