Effect of Superficial Large Vessel Insulation Combined with Self-heating Warm Paste on Intraoperative Hypothermia in Patients Undergoing Urologic Surgery

This study aimed to explore the application effect of superficial large vessel insulation combined with self-heating warm paste on intraoperative hypothermia in patients undergoing urologic surgery.

This study included 313 patients who underwent urologic surgery in Taizhou Hospital of Zhejiang Province Affiliated to Wenzhou Medical University from May 2023 to March 2024. After 13 patients with incomplete clinical data, abnormal basal metabolism and preoperative skin injury were excluded, 300 patients were finally included. In accordance with the intraoperative methods of insulation, the patients were divided into three groups: Conventional insulation group (group A, n = 102), superficial large vessel insulation group (group B, n = 100) and superficial large vessel insulation combined with self-heating warm paste group (group C, n = 98). Baseline data, intraoperative core temperature, and incidence of intraoperative hypothermia, intraoperative skin injury and postoperative chills in patients were retrospectively evaluated.

A difference was found in the core temperature amongst the three groups at 1, 2 and 3 h after anaesthesia. The core temperature in groups A and B was overtly lower than that in group C (p < 0.001). No statistically significant difference was observed in the incidence of intraoperatively acquired pressure injury amongst patients in groups A-C (p > 0.05). The incidence of thermal injury and postoperative shivering in group C was significantly lower than that in groups A and B (p < 0.05).

Broader adoption of superficial large vessel warming combined with self-heating thermal paste is recommended whilst acknowledging that feasibility and resource constraints in various surgical settings may influence practical application. Future research should focus on the implementation of these techniques in different clinical environments and their associated resource requirements.
