Study Objective: To investigate the efficacy of warmed, humidified inspired oxygen (O2) 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 O2 therapy (control group, n = 15), or warmed (42°C) humidified O2 (treatment group, n = 15) for the initial 90 postoperative minutes.
Measurements: Core (tympanic) temperature, dry mouth score and shivering score.
Main Results: Tympanic temperature was similar in both groups on admission (≈35.8°C). Rewarming rate in the first postoperative hour was greater in the treatment group (0.7 ± 0.1°C · hr−1) compared to the control group (0.4 ± 0.1°C · hr−1) (p = 0.03). Patients receiving the warmed, humidified O2 had a lower incidence of dry mouth compared to the control group (p = 0.03). The incidence of shivering was low and similar in both groups.
Conclusions: Warming and humidifying inspired O2 hastens recovery from hypothermia in postoperative patients.
