[Respiratory gas exchange during total body hyperthermia in man].

Respiratory gas exchange was evaluated using indirect calorimetry during total body hyperthermia (TBH) in 7 postoperative patients with disseminated gastric cancer to the peritoneal cavity. TBH was induced using veno-venous bypass and extracorporeal circuit incorporating a heat exchanger to keep pulmonary arterial temperature 42 degrees C. The high temperature was maintained for 3 hours under general anesthesia with droperidol (0.
