PURPOSE
The aim of this study was to compare the change in body temperature between the cotton blanket group and forced-air warming blanket group during arthroscopic shoulder surgery. In both groups irrigation fluid at room temperature (22 degrees C) was used.
METHODS
We randomly assigned 44 American Society of Anesthesiologists physical status I and II patients scheduled for elective shoulder arthroscopic surgery to receive 1 cotton blanket (group I, n = 22) or a forced-air warming blanket (group II, n = 22). Body temperatures were measured with an esophageal stethoscope, which was inserted immediately after intubation.
RESULTS
A significant difference in body temperatures was observed at 60 minutes after induction (P = .0192), 90 minutes after induction (P = .0004), 120 minutes after induction (P = .0003), and 150 minutes after induction (P = .0228). Shivering on arrival in the postanesthesia care unit was found in 15 patients in group I (68.1%) and only 1 patient in group II (4.5%).
CONCLUSIONS
We conclude that forced-air warming is significantly more efficient than a cotton blanket alone at maintaining perioperative normothermia during arthroscopic shoulder surgery.
LEVEL OF EVIDENCE
Level I, randomized controlled trial.
目的
本研究旨在比较关节镜下肩部手术期间棉毯组和强制空气加温毯组的体温变化。两组均使用室温（22摄氏度）的冲洗液。
方法
我们将44例美国麻醉医师协会身体状况I级和II级、计划进行择期肩部关节镜手术的患者随机分为两组，一组使用1条棉毯（I组，n = 22），另一组使用强制空气加温毯（II组，n = 22）。在插管后立即插入食管听诊器测量体温。
结果
诱导后60分钟（P = 0.0192）、90分钟（P = 0.0004）、120分钟（P = 0.0003）和150分钟（P = 0.0228）时，体温存在显著差异。I组有15例患者（68.1%）在进入麻醉后护理单元时出现寒战，而II组只有1例患者（4.5%）出现寒战。
结论
我们得出结论，在关节镜下肩部手术期间，强制空气加温在维持围手术期正常体温方面明显比单独使用棉毯更有效。
证据水平
I级，随机对照试验。
