Perioperative hypothermia in adults

: In perioperative hypothermia, a central temperature of less than 36 degrees C develops in connection with anaesthesia and operation. Perioperative hypothermia constitutes a daily problem which results in increased morbidity and mortality in risk groups. The influence of anaesthetic agents on temperature regulation is reviewed. The postoperative hypothermic phase with increased oxygen requirement on rewarming increases the risk of development of complications, including cardiac complications. The risk groups and prophylactic methods for hypothermia are mentioned. Higher temperatures in the anaesthetic room, prewarming of infusion fluids and employment of infusion warmers should be employed with all anaesthetics. In patients in risk groups, extensive employment of combined methods of prevention of hypothermia is recommended.
