Impact of Intraoperative Hypothermia on Outcomes of Flexible Ureteroscopic Holmium Laser Lithotripsy under General Anesthesia in Urolithiasis Patients. A cohort of 86 patients undergoing flexible ureteroscopic holmium laser lithotripsy (FURSL) in the Surgical Suite of Xijing Hospital between September 2024 and March 2025 were enrolled. Patients were stratified into hypothermic (core temperature <36°C, n=60) and non-hypothermic groups (n=26) based on intraoperative hypothermia occurrence. Comparison of basic surgical indicators between the two patient groups: Intraoperative blood loss, Time to extubation (from discontinuation of anesthetic agents to tracheal extubation), Operating room time, Post-anesthesia care unit (PACU) length of stay / PACU stay duration, Hospital length of stay / Duration of hospitalization, Steward score (in general anesthesia patients);Incidence of postoperative adverse reactions including shivering, agitation, and postoperative nausea and vomiting (PONV). The hypothermia group exhibited significantly higher values than the non-hypothermia group for intraoperative blood loss, time to extubation, operating room time, PACU stay duration, and hospital length of stay. Statistically significant differences (P<0.05) were particularly observed in time to extubation, operating room time, and PACU stay duration. The hypothermia group demonstrated significantly higher incidence rates of shivering, agitation, and postoperative nausea and vomiting (PONV) compared to the non-hypothermia group. Statistically significant differences (P<0.05) were observed specifically in shivering and agitation incidence rates. In patients undergoing ureteroscopic holmium laser lithotripsy under general anesthesia, the occurrence of intraoperative hypothermia exerts significant perioperative implications. This condition conflicts with the principles of Enhanced Recovery After Surgery (ERAS). Consequently, implementing rigorous intraoperative warming protocols and optimizing thermal care interventions are imperative to prevent hypothermia, thereby safeguarding postoperative recovery efficacy.
