Unintentional perioperative hypothermia causes serious adverse effects to surgical patients. Thermal suit (T-Balance ) is an option for passive warming perioperatively. We hypothesized that the thermal suit will not maintain normothermia more efficiently than conventional cotton clothes when also other preventive procedures against unintentional hypothermia are used.
One hundred patients were recruited to this prospective, randomized trial. They were allocated to the Thermal Suit group or a Control group wearing conventional hospital cotton clothes. All patients received our institution's standard treatment against unintentional hypothermia including a warming mattress, a forced-air upper body warming blanket and a warming device for intravenous fluids. Eardrum temperature was measured pre-operatively. In the operating room and post-anaesthesia care unit temperatures were measured from four locations: oesophagus, left axilla, dorsal surface of the left middle finger and dorsum of the left foot. The primary outcome measure was temperature change during robotic-assisted laparoscopic radical prostatectomy.
The temperatures of 96 patients were analysed. There was no difference in mean core temperatures, axillary temperatures or skin temperatures on the finger between the groups. Only foot dorsum temperatures were significantly lower in the Thermal Suit group. Intraoperative temperature changes were similar in both groups. In the post-anaesthesia care unit temperature changes were minimal and they did not differ between the groups.
Provided that standard preventive procedures in maintaining normothermia are effective the thermal suit does not provide any additional benefit over conventional cotton clothes during robotic-assisted laparoscopic radical prostatectomy.
围手术期意外低温会给手术患者带来严重不良影响。保暖套装（T-Balance）是围手术期被动保暖的一种选择。我们假设，在采用其他预防意外低温的措施时，保暖套装维持正常体温的效果不会比传统棉质衣物更好。
招募了100名患者参与这项前瞻性随机试验。他们被分配到保暖套装组或穿着传统医院棉质衣物的对照组。所有患者均接受了我们机构针对意外低温的标准治疗，包括暖床垫、强制空气上身保暖毯和静脉输液加温装置。术前测量鼓膜温度。在手术室和麻醉后护理单元，从四个部位测量体温：食管、左腋窝、左手食指背面和左脚背。主要观察指标是机器人辅助腹腔镜根治性前列腺切除术中的体温变化。
分析了96名患者的体温。两组之间的平均核心体温、腋窝温度或手指皮肤温度没有差异。只有保暖套装组的脚背温度显著较低。两组术中体温变化相似。在麻醉后护理单元，体温变化很小，两组之间没有差异。
如果维持正常体温的标准预防措施有效，那么在机器人辅助腹腔镜根治性前列腺切除术中，保暖套装相对于传统棉质衣物并没有提供任何额外的益处。
