A randomized controlled comparison of tourniquet and local adrenaline infiltration for control of bleeding was performed in patients undergoing bilateral carpal tunnel release under local anaesthesia. Visual analogue scores for intra-operative pain were substantially greater for tourniquet (mean score 4.7) than for adrenaline (2.2). Incomplete control of bleeding was responsible for longer operating time and for the surgeons' perception of slightly greater operative difficulty with the use of adrenaline. There were no complications attributable to the use of adrenaline. The use of adrenaline-containing local anaesthesia for carpal tunnel release avoids tourniquet pain and is preferred by patients.
在接受局部麻醉下双侧腕管松解术的患者中，进行了一项关于使用止血带和局部肾上腺素浸润控制出血的随机对照比较。止血带组术中疼痛的视觉模拟评分（平均评分4.7）显著高于肾上腺素组（2.2）。肾上腺素组出血控制不完全导致手术时间延长，并且外科医生感觉使用肾上腺素时手术难度略大。未出现因使用肾上腺素导致的并发症。在腕管松解术中使用含肾上腺素的局部麻醉可避免止血带疼痛，且患者更倾向于选择该方法。
