Abstract

Objective: To evaluate the incidence of perioperative hypothermia and its associated factors in patients undergoing prolonged surgery at Bach Mai Hospital during 2024–2025. Methods: A prospective cross-sectional study was conducted on 172 patients aged ≥18 years, ASA I–III, undergoing open or laparoscopic abdominal surgery lasting ≥2 hours. Core temperature was monitored intraoperatively. Associations were analyzed using odds ratios (OR) with 95% confidence intervals. Results: The incidence of hypothermia was 65.1% (112/172), with mild, moderate, and severe hypothermia accounting for 71.4%, 19.6%, and 10%, respectively. Significant associated factors included age ≥65 years (OR=1.44), ASA III (OR=1.50), open surgery (OR=1.17), operative time ≥180 minutes (OR=1.14), absence of warming devices (OR=2.53), intravenous fluid volume ≥1000 ml (OR=2.25), and irrigation fluid ≥1000 ml (OR=1.80). Gender and nutritional status showed no correlation with hypothermia. Conclusion: Hypothermia is common during prolonged surgeries. Several risk factors—including advanced age, higher ASA class, open surgical technique, long operative duration, and inadequate warming—significantly increase the likelihood of hypothermia. Enhanced temperature monitoring and active warming strategies should be integrated to minimize perioperative complications.
