This study was conducted to compare the effects of heat preservation by two recommended methods, heated infiltration solutions and forced-air heating blankets, in patients undergoing liposuction under general anesthesia.
Forty patients were divided into four groups based on whether heated infiltration solutions or forced-air heating blankets were used. Group A received general anesthesia liposuction plastic surgery routine temperature care. Based on the care measures of group A, heated infiltration solutions were used in group B; forced-air heating blanket was used in group C; and heated infiltration solutions and forced-air heating blankets were both used in group D. The primary end point was intraoperative and perioperative temperature measured with an infrared tympanic membrane thermometer. Secondary end points included surgical outcomes, subjective experience, and adverse events.
Compared with group A, the intraoperative body temperatures of groups B, C, and D were significantly higher, indicating that the two intervention methods were helpful on increasing the core body temperature. Pairwise comparisons of these three groups showed that there was no significant difference between group C and group D. However, using forced-air heating blankets had a marked effect compared with using heated infiltration solutions alone at three time points. The same trend could be seen in other surgical outcomes.
Heated infiltration solutions and forced-air heating blankets could reduce the incidence of intraoperative hypothermia and improve patients' prognosis after liposuction under general anesthesia. Compared with the heated infiltration fluid, the forced-air heating blanket may have a better thermal insulation effect.

本研究旨在比较两种推荐的保温方法（加热渗透液和强制空气加热毯）在全身麻醉下接受吸脂术患者中的效果。
40 名患者根据是否使用加热渗透液或强制空气加热毯分为四组。组 A 接受全身麻醉吸脂整形手术常规温度护理。基于组 A 的护理措施，组 B 使用加热渗透液；组 C 使用强制空气加热毯；组 D 使用加热渗透液和强制空气加热毯。主要终点是用红外鼓膜温度计测量术中及围术期体温。次要终点包括手术结果、主观体验和不良事件。
与组 A 相比，组 B、C 和 D 的术中体温明显升高，表明两种干预方法有助于提高核心体温。这三组的两两比较显示，组 C 和组 D 之间没有显著差异。然而，与单独使用加热渗透液相比，在三个时间点使用强制空气加热毯的效果更为显著。其他手术结果也呈现出同样的趋势。
加热渗透液和强制空气加热毯可降低全身麻醉下吸脂术中低体温的发生率，改善患者术后预后。与加热渗透液相比，强制空气加热毯可能具有更好的保温效果。
