摘要

To evaluate the effectiveness of a phased active warming protocol in preventing intraoperative hypothermia during Da Vinci robot-assisted radical resection for rectal cancer. A single-center retrospective cohort analysis examined patients undergoing Da Vinci robot-assisted rectal cancer resection from January 1, 2022, through December 31, 2024. Using 1:1 propensity score matching, patients receiving phased active warming protocol were matched with those under routine thermal care. Variables for matching encompassed age, sex, body mass index, American Society of Anesthesiologists classification, surgical duration, and anesthesia time. Primary outcome measured was intraoperative hypothermia incidence (core temperature below 36 °C). Secondary outcomes covered mean core temperature, postoperative shivering evaluated through Bedside Shivering Assessment Scale, surgical site infection rates, blood transfusion needs, hospital stay duration, and perioperative costs. Following propensity score matching, each group contained 144 patients (total n = 288). Hypothermia occurrence dropped markedly in the intervention cohort (26 cases [18.1%] versus 70 cases [48.6%], p < 0.001). End-of-surgery core temperature showed higher values in the intervention cohort (36.4 ± 0.5 °C compared to 35.8 ± 0.6 °C, p < 0.001). Shivering after surgery (BSAS score of 1 or greater) demonstrated reduced frequency in the intervention cohort (18 patients [12.5%] versus 50 patients [34.7%], p < 0.001). Wound infection rates decreased in the intervention cohort (6 cases [4.2%] versus 17 cases [11.8%], p = 0.022). Hospital stays shortened for the intervention cohort (8.2 ± 2.1 days compared to 10.5 ± 3.4 days, p < 0.001). The phased active warming approach substantially decreased hypothermia occurrence and enhanced perioperative outcomes in Da Vinci robot-assisted rectal cancer resection patients, demonstrating clinical value warranting widespread adoption.
