Objective To understand the current status of hypothermia in orthopedic endoscopic surgery and to analyze its risk factors. Methods Convenience sampling method was chosen to collect study data from 289 patients who underwent orthopedic endoscopic surgery from September 2023 to February 2024 in a hospital. The current status of intraoperative hypothermia in orthopedic endoscopic surgery was counted and the significant factors were explored based on logistic regression analysis method. Results Intraoperative hypothermia occurred in 168 of 289 orthopedic endoscopic surgery patients (58.13%). The statistical results showed that: BMI≥24kg·m-2(0R=0.052, 95%CI:0.003~0.902), basal body temperature (OR=0.002, 95%CI:0.001~0.033), intraoperative lavage volume (OR=1.357, 95%CI: 1.246~2.952), and anesthesia time ≥2.5h (OR= 14.538, 95% CI: 1.529~38.230) were significant factors influencing the incidence of intraoperative hypothermia in patients undergoing orthopedic endoscopic surgery (P<0.05). Conclusion Unexpected intraoperative hypothermia is very common in patients undergoing surgery for orthopedic endoscopic procedures, where BMI, basal body temperature, amount of intraoperative lavage, and duration of anesthesia are all independently present risk factors for these types of surgical patients. Focus should be placed on the orthopedic endoscopic surgery population with low BMI, low basal body temperature, longer expected anesthesia time, and higher volume of intraoperative lavage, and preventive measures should be implemented in a targeted manner to reduce the probability of intraoperative hypothermia.
