Abstract

Skin blisters occur in up to 20% of patients after total knee arthroplasty (TKA). Tourniquet release results in a limb volume increase of 10%. We hypothesized that releasing tourniquet before application of circumferential dressing will decrease blister formation. A prospective study was conducted on 135 consecutive primary TKAs. The tourniquet was released immediately after wound closure to allow for re-perfusion and then a dressing was applied. These patients were compared to a historical cohort of 200 primary TKAs, where the tourniquet was released after application of dressing. There was a significant difference in the incidence of blisters between the two groups [Late 7.5% (15/200) vs early release 2.2% (3/135) P=0.028]. Releasing the tourniquet prior to dressing application has reduced the incidence of blistering following TKA.

摘要

全膝关节置换术（TKA）后，高达20%的患者会出现皮肤水泡。止血带松开后肢体体积会增加10%。我们推测，在应用环形敷料之前松开止血带会减少水泡形成。对135例连续的初次全膝关节置换术患者进行了一项前瞻性研究。伤口闭合后立即松开止血带以实现再灌注，然后应用敷料。将这些患者与200例初次全膝关节置换术的历史队列患者进行比较，后者在应用敷料后松开止血带。两组之间水泡发生率存在显著差异[后期7.5%（15/200）vs早期松开2.2%（3/135），P=0.028]。在应用敷料之前松开止血带降低了全膝关节置换术后水泡的发生率。
