The impact of preoperative nutritional status, intraoperative fluid administration volume, operating room temperature, and anesthesia duration on intraoperative hypothermia in elderly patients undergoing total joint replacement under general anesthes

There are numerous factors associated with the occurrence of IHC in elderly patients undergoing joint replacement surgery, primarily including intraoperative fluid administration volume, operating room temperature, anesthesia duration, and ALB. The risk prediction nomogram model constructed based on these factors demonstrates certain predictive value for the risk of IHC occurrence. Clinically, early screening of high-risk populations and implementation of targeted nursing interventions hold significant implications for clinical outcomes.
