Hypothermia is a common intraoperative and immediate postoperative complication. Hypothermia causes morbidity from shivering, hypotension, cyanosis, and respiratory diseases. In severe cases, bradycardia, premature ventricular contractions, and even ventricular fibrillation may occur. ⋯ Restoration of normal body temperature is achieved by radiant heaters, heated mattresses, and heated humidifiers. Astute assessment, quick response, and correct interventions by the nurse can often minimize risk of postanesthesia hypothermia. These principles are illustrated in a case study of a PACU patient in a large teaching trauma hospital.

The following article includes a brief review of hypothermia and describes contributing factors that cause hypothermia in the operating room as well as the methods used to rewarm patients in the PACU. Thermadrape coverings (OR Concepts, Inc, Roanoke, TX) were studied to determine if they were effective in maintaining body temperature within a normothermic range. Of 55 patients evaluated in the PACU, 18 (32%) who received Thermadrape coverings in the perioperative period remained normothermic. The methods used to rewarm postanesthesia patients included three combinations: Thermadrape and warmed cotton blankets, warmed cotton blankets and heat lamps, and warmed cotton blankets alone.
