Investigating The Incidence of Intraoperative Hypothermia and Associated Risk Factors in Laparoscopic Cholecystectomy Patients: A Pilot Prospective Cohort Study

Abstract

Intraoperative hypothermia is a frequent and preventable complication during surgery. Despite international evidence, data from Libya remain scarce, especially for laparoscopic procedures. This study was conducted to assess the incidence of intraoperative hypothermia and identify associated risk factors in patients undergoing laparoscopic cholecystectomy. A prospective cohort study was conducted at a single hospital in Libya from October to December 2024. Twenty-seven adult patients undergoing elective laparoscopic cholecystectomy were enrolled. Intraoperative core temperature was recorded every 15 minutes. Demographic and clinical data were analyzed using appropriate statistical methods, including logistic regression. Hypothermia occurred in 77.8% of patients. Risk factors significantly associated with hypothermia included older age, lower BMI, greater intravenous fluid volume, lower operating room temperature, and longer surgery duration. Sex, ASA score, and fasting duration were not significantly associated. Intraoperative hypothermia is highly prevalent among laparoscopic cholecystectomy patients in Libya. Several modifiable risk factors were identified. Preventive measures should be implemented to reduce its occurrence and improve patient outcomes
