Inadvertent intraoperative hypothermia (core temperature <36°C) is a frequently preventable complication with several adverse consequences. Our study aimed to determine the overall incidence of inadvertent and its risk factors associated clinical outcomes in this national survey China.We conducted cross-sectional 30 days postoperative follow-up from November 2014 through August 2015. A total 3132 eligible patients underwent general anesthesia were randomly selected 28 hospitals nationwide China.The was as high 44.3%, which cumulative rates being 17.8%, 36.2%, 42.5% 44.1% within 1 h, 2 3 h 4 respectively following induction anesthesia. All warmed passively by covering surgical draping, sheets or cotton blankets, whereas only 14.2% received active warming space heaters electric heater electronic blankets. Compared normothermic patients, more ICU admit, longer PACU hospital days, but no difference site infection (SSI) 30-day mortality. Several shown be decreased hypothermia. They are (OR = 0.46, 95% CI 0.26-0.81), BMI ≥ 25 0.54, 0.45-0.65), higher baseline core 0.04, 0.03-0.06), ambient 0.83, 0.78-0.88). Risk an increased included major-plus surgery 1.49, 1.23-1.79), long (>2 h) 2.60, 2.09-3.24).The China high, rate during operation low. Hypothermia shivering, admissions, days.
