Incidence of Inadvertent Intraoperative Hypothermia and Its Risk Factors in Patients Undergoing General Anesthesia in Beijing: A Prospective Regional Survey.
Inadvertent intraoperative hypothermia (core temperature 2 h (OR = 3.44, 95% CI 1.90-6.22,), and intravenous un-warmed fluid (OR = 2.45, 95% CI 1.45-4.12) significantly increased the risk of hypothermia.The incidence of inadvertent intraoperative hypothermia in Beijing is high, and the rate of active warming of patients during operation is low. Concern for the development of intraoperative hypothermia should be especially high in patients undergoing major operations, requiring long periods of anesthesia, and receiving un-warmed intravenous fluids.
