Influencing factors and preventive management for intraoperative hypothermia in elderly patients undergoing major abdominal surgery
Objective To investigate the incidence rate of intraoperative hypothermia in elderly patients undergoing major abdominal surgery and analyze the related factors for intraoperative hypothermia.Methods A total of 146 elderly patients who underwent major abdominal surgery in our hospital between January 2022 and January 2023 were recruited as the study subjects.The incidence of intra-operative hypothermia and its impact on postoperative complications were statistically analyzed.Logistic regression model was used to analyze the related influencing factors for intraoperative hypothermia in elderly patients undergoing major abdominal surgery.SPSS statistics 22.0 was employed for statistical analysis.Data comparison between two groups was performed using student's t test or Chi-square test depending on data type.Results Among the 146 subjected patients,76 cases(52.05%)experienced intraoperative hypothermia.The incidence rates of shivering during anesthesia recovery,metabolic acidosis and electrolyte disturbance were signifi-cantly higher in patients with intraoperative hypothermia than those with normal body temperature(P<0.05).Binary logistic regression analysis showed that body mass index≥24 kg/m2(OR=0.212,95%CI 0.073-0.615)and warming infusion solutions(OR=0.459,95%CI 0.279-0.756)were protective factors,and anesthesia time≥3 h(OR=2.010,95%CI 1.604-2.518)and intraoperative infusion volume>2 000 ml(OR=1.912,95%CI 1.164-3.139)were risk factors for intraoperative hypothermia in elderly patients with major abdominal surgery.Conclusion The incidence of intraoperative hypothermia is high among elderly patients undergoing major abdominal surgery,and it will increase the incidence rates of various postoperative complications.It is suggested that clinical composite measures should be adopted to reduce the incidence rate of intraoperative hypothermia.
