Fig. 2From: Effect of active forced air warming during the first hour after anesthesia induction and intraoperation avoids hypothermia in elderly patientsPerioperative body temperature. Preoperative and postperative core temperature of patients were measured ussinng tympanic membrane thermometer. Intraoperative core temperature was recorded at 30-min intervals via nasopharyngeal probe after induction of anesthesia. Baseline: immediately after arrival in operation room; intraoperative 0 min: immediately after insertion of nasopharyngeal probe; PACU 0 min: immediately after arrival at PACU; PACU 15, and 30 min: 15 and 30 min after arrival at PACU. * represents P<, 05 compared with Group L, ** represents P < .001 compared with Group L.Back to article page
