Construction of intraoperative hypothermia risk prediction model for elderly total hip arthroplasty patients
Objective:A hypothermia risk prediction model in elderly total hip arthroplasty(THA)was constructed.Methods:The data of 252 elderly patients who underwent hip replacement surgery from January 2019 to May 2022 were included,and the risk factors for hypothermia were analyzed,and a nomogram prediction model was constructed and validated.Results:Logistic regression analysis showed that anesthesia time,operation time,operating room ambient temperature,intraoperative infusion,and surgical bleeding were independent influencing factors of intraoperative hypothermia in elderly people with THA(P<0.05).The AUC of the nomogram prediction model is 0.888(95%CI:0.849~0.928),and the consistency results are close to the ideal predictive ability,and the clinical decision curve shows that the threshold is 0.15~0.95,which can benefit clinically.Conclusion:The model constructed in this study can accurately predict intraoperative hypothermia in elderly patients with total hip arthroplasty,which can provide reference for clinical decision-making.
