Analysis of Related Influencing Factors for Intraoperative Hypothermia in Patients Undergoing Artificial Knee Joint Surface Replacement Surgery
Objective:To analyze the relevant influencing factors of intraoperative hypothermia in patients undergoing artificial knee joint surface replacement surgery.Method:A random sampling method was used to select 108 patients who underwent knee joint surface replacement surgery in the Affiliated Hospital of Putian University from April to December 2022 as the research subjects.The changes in rectal temperature during the surgery were observed and recorded.If the rectal temperature during the surgery was less than 36℃,it was determined that hypothermia had occurred.Patients with intraoperative hypothermia were included in the occurrence group,while those without hypothermia were included in the normal group.Patients'general information were investigated and compared by using a baseline data survey scale to identify relevant influencing factors.Result:45 out of 108 patients undergoing artificial knee joint surface replacement experienced hypothermia during the surgery,with an incidence rate of 41.67%;the proportion of patients in the age group≥75 years old,operating room temperature<21℃,intraoperative infusion volume≥1 000 mL and surgery time≥2.5 hours in the occurrence group were higher than those in the normal group,the differences were statistically significant(P<0.05);the results of logistic regression analysis showed that age≥75 years,operating room temperature<21℃,intraoperative infusion volume≥1 000 mL and surgical time≥2.5 h were the influencing factors for intraoperative hypothermia in patients undergoing artificial knee joint surface replacement surgery(OR>1,P<0.05).Conclusion:The incidence of intraoperative hypothermia in patients undergoing artificial knee joint surface replacement is relatively high,which is influenced by factors such as age,operating room temperature,intraoperative infusion volume and surgical time.
