The purpose of this study was to determine if letting down the tourniquet prior to closure after carpal tunnel release decreases the amount of post-operative ecchymosis and subsequent post-operative pain. We prospectively studied 18 consecutive patients who were undergoing bilateral open carpal tunnel releases. The side done first was randomized and the tourniquet was released to obtain hemostasis prior to closure on this side only. The second side was completed, closed, and dressed prior to letting the tourniquet down. The patients' pre-operative and post-operative pain scores were recorded, as was an ecchymosis score at the 10-day follow-up visit. The results showed no significant difference between the two groups in either pain or ecchymosis. We conclude that the added surgical time required for letting the tourniquet down and obtaining hemostasis prior to closure in a carpal tunnel is unnecessary.
本研究的目的是确定在腕管松解术后关闭创口前松开止血带是否能减少术后瘀斑量及后续的术后疼痛。我们前瞻性地研究了18例连续接受双侧开放性腕管松解术的患者。首先进行手术的一侧被随机分配，仅在该侧关闭创口前松开止血带以实现止血。另一侧在松开止血带之前完成手术、关闭创口并包扎。记录患者术前和术后的疼痛评分，以及在10天随访时的瘀斑评分。结果显示两组在疼痛或瘀斑方面均无显著差异。我们得出结论，在腕管手术中，关闭创口前松开止血带并实现止血所需的额外手术时间是不必要的。
