摘要：

Study Objective: To investigate the efficacy of warmed, humidified inspired oxygen (O-2) for the treatment of mildly hypothermic postoperative patients. Design: Prospective, randomized, unblinded clinical trial. Setting: Postanesthesia care unit in a tertiary care hospital Patients and Interventions: 30 ASA physical status I, II, and III patients following intraabdominal surgical procedures were randomly assigned to receive either routine O-2 therapy (control group, n = 15), or warmed (42 degrees C) humidified O-2 (treatment group, n = 15)for the initial 90 postoperative minutes. Measurements: Core (tympanic) temperature, dry month score and shivering score. Main Results: Tympanic temperature was similar in both groups on admission (approximate to 35.8 degrees C). Rewarming rate in the first postoperative hour was greater in the treatment group (0.7 +/- 0.1 degrees C . hr(-1)) compared to the control group (0.4 +/- 0.1 degrees C . hr(-1)) (p = 0.03). Patients receiving the warmed humidified O-2 had a lower incidence of dry mouth compared to the control group (p = 0.03). The incidence of shivering was lord and similar in both groups. Conclusions: Warming and humidifying inspired O-2 hastens recovery from hypothermia in postoperative patients. (C) 2000 by Elsevier Science Inc.
