Effect of active core rewarming on body temperature and bioelectrical impedance 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.
