Incidence and Risk Factors of Hypothermia in Elderly Patients Undergoing Laparoscopic Hysterectomy under General Anesthesia
Objective:To explore the incidence and risk factors of hypothermia in elderly patients undergoing laparoscopic hysterectomy under general anesthesia.Method:A total of 200 elderly patients who underwent laparoscopic hysterectomy under general anesthesia at Shiqiao Hospital,Panyu District,Guangzhou City from July 2021 to July 2023 were retrospectively selected.The incidence of hypothermia and related risk factors were identified through the application of univariate and multivariate analysis.Among the 200 selected patients,those who experienced hypothermia were included in group A,while those who did not were included in group B.Result:There was no statistically significant difference between group A and group B in terms of American stroke association(ASA)grade Ⅲ classification(P>0.05);the proportion of patients with intraoperative intravenous infusion volume>1 000 mL,the age≥70 years,the intraoperative abdominal flushing fluid volume>1 500 mL,anxiety before surgery,the intraoperative carbon dioxide pneumoperitoneum time>120 min,the intraoperative bleeding volume>150 mL,the intraoperative carbon dioxide heated to 37℃,and the body mass index(BMI)<24 kg/m2,the intraoperative carbon dioxide infusion volume>200 L and mild to moderate anemia before surgery were compared between the two groups,the differences were statistically significant(P<0.05).The results of multiple factors showed that intraoperative warming carbon dioxide to 37℃was protective factor;the risk factors for hypothermia in elderly patients undergoing laparoscopic hysterectomy under general anesthesia included mild to moderate anemia before surgery,abdominal lavage fluid volume>1 500 mL during surgery,age≥70 years,carbon dioxide pneumoperitoneum time>120 min during surgery,carbon dioxide perfusion volume>200 L during surgery,intravenous infusion volume>1 000 mL during surgery,preoperative anxiety,BMI<24 kg/m2,and intraoperative bleeding volume>150 mL.Conclusion:The incidence of hypothermia in elderly patients undergoing laparoscopic hysterectomy under general anesthesia is relatively high,and the causes of hypothermia are closely related to intraoperative carbon dioxide warming,age of patient,abdominal flushing fluid volume,preoperative anemia,pneumoperitoneum time,and carbon dioxide perfusion.Therefore,in practice,specific measures need to be formulated to reduce the incidence of hypothermia.
