Although laparoscopic radical resection for colorectal cancer offers advantages such as minimal invasiveness and rapid recovery, the incidence of intraoperative hypothermia remains high, significantly affecting patient prognosis. Traditional intraoperative thermoprotection measures have limitations in addressing heat redistribution following anaesthetic induction and the sustained loss of body heat during prolonged surgery. This study hypothesises that a comprehensive preope
To investigate effects of preoperative warming on hypothermia and recovery in laparoscopic colon cancer surgery.
From August 2021 to August 2025, 118 colon cancer patients undergoing laparoscopic radical resection were randomized into observation and control groups (n = 59 each). The control group received routine intraoperative warming, while the observation group received additional preoperative comprehensive warming. Comparisons included core temperature, hypothermia incidence, perioperative indicators, bleeding-related outcomes, coagulation function, and adverse reac
No significant differences were found in baseline data or preoperative temperature (P > 0.05). Compared with controls, the observation group had higher core temperature at 30 minutes, 1 hour, and end of surgery, and a lower hypothermia rate (11.86% vs 33.90%, P < 0.05). The observation group also showed shorter operative time, anesthesia recovery time, first flatus time, hospital stay, lower Visual Analog Scale score on day 1, less blood loss and drainage, and better mobility on day 1 (P < 0.05). Fewer patients required intraoperative transfusion (5.08% vs 15.25%, P < 0.05). Coagulation parameters remained stable postoperatively in the observation group and were significantly better than controls (P < 0.05). The total incidence of postoperative adverse events was lower in the observation group (3.39% vs 16.95%, P < 0.05).
Preoperative comprehensive warming effectively maintains core temperature, reduces hypothermia, protects coagulation, minimizes adverse reactions, and promotes recovery in laparoscopic colon cancer surgery.
Core Tip: This randomized controlled trial demonstrates that initiating comprehensive warming interventions before anesthesia induction effectively prevents intraoperative hypothermia in laparoscopic colon cancer surgery. The preoperative warming strategy not only maintains core temperature but also preserves coagulation function and significantly reduces postoperative shivering and recovery time, offering a practical and enhanced protocol for perioperative care to improve patient outcomes.
