From: Active core rewarming avoids bioelectrical impedance changes in postanesthetic patients

Effect of active core rewarming on physical variables of postoperative patients. Sixty adult patients underwent laparoscopic cholecystectomy under balanced inhalation anesthesia. A group of patients (n = 30) was treated with warmed parenteral solutions (38.5°C) and a cotton blanket. This group is referred to as Active Core Rewarming (•). The other group (n = 30) was treated with room-temperature parenteral solutions and a cotton blanket. This group is referred to as Passive External Rewarming (o). The values are expressed as the mean (s). All P values are < 0.001.
