The study aimed to evaluate the effect of forced-air warming blanket combined with conventional thermal insulation measures on inadvertent perioperative hypothermia (IPH) in elderly patients undergoing laparoscopic radical resection of colorectal cancer. A total of 70 elderly patients undergoing laparoscopic radical resection of colorectal cancer with general anesthesia were included, and divided into conventional warming treatment (CT) group or forced-air warming treatment (FT) group. In the FT group, based on the conventional warming strategy, patients received prewarming with the forced-air warming blanket (38°C) for ≥20 minutes before induction of anesthesia, and received this treatment continuously during operation. The core body temperature, recovery time from anesthesia, extubating time, and length of stay in the postanesthesia care unit were recorded. The incidence of IPH and postoperative shivering was observed. The incidence of IPH was significantly lower, and average minimum body temperature during the operation was significantly higher in the FT group than that in the CT group (5.7% vs. 22.8% and 36.23°C vs. 35.89°C, respectively). The intraoperative body temperature decreased less (0.32°C vs. 0.69°C), the recovery time from anesthesia was faster (12.8 minutes vs. 17.1 minutes), and the incidence of postoperative shivering was less (2.8% vs. 28.6%) in the FT group than the CT group. In elderly patients undergoing laparoscopic radical resection of colorectal cancer, use of forced-air warming blankets combined with conventional warming measures is more effective to maintain normal body temperature during the perioperative period and reduce the incidence of IPH.
本研究旨在评估空气对流加热毯联合常规保温措施对行腹腔镜结直肠癌根治术老年患者围术期低体温（IPH）的影响。共纳入 70 例行全身麻醉下腹腔镜结直肠癌根治术的老年患者，分为常规保温治疗（CT）组或空气对流加热治疗（FT）组。FT 组在常规保温策略的基础上，在麻醉诱导前接受空气对流加热毯（38°C）预热≥20 分钟，并在手术过程中持续接受此治疗。记录核心体温、麻醉恢复时间、拔管时间和麻醉后监护病房停留时间。观察 IPH 和术后寒战的发生率。FT 组的 IPH 发生率明显低于 CT 组（5.7%比 22.8%），术中平均最低体温明显高于 CT 组（36.23°C 比 35.89°C）。FT 组术中体温下降较少（0.32°C 比 0.69°C），麻醉恢复时间较快（12.8 分钟比 17.1 分钟），术后寒战发生率较低（2.8%比 28.6%）。在接受腹腔镜结直肠癌根治术的老年患者中，空气对流加热毯联合常规保温措施更有效地维持围术期正常体温，降低 IPH 的发生率。
