Peripheral nerve block is an accepted method in lower limb surgeries regarding its convenience and good tolerance by the patients. Quick performance and fast sensory and motor block are highly demanded in this method. The aim of the present study was to compare 2 different methods of sciatic and tibial-peroneal nerve block in lower limb surgeries in terms of block onset.
In this clinical trial, 52 candidates for elective lower limb surgery were randomly divided into 2 groups: sciatic nerve block before bifurcation (SG; n = 27) and separate tibial-peroneal nerve block (TPG; n = 25) under ultrasound plus nerve stimulator guidance. The mean duration of block performance, as well as complete sensory and motor block, was recorded and compared between the groups.
The mean duration of complete sensory block in the SG and TPG groups was 35.4 ± 4.1 and 24.9 ± 4.2 minutes, respectively, which was significantly lower in the TPG group (P = 0.001). The mean duration of complete motor block in the SG and TPG groups was 63.3 ± 4.4 and 48.4 ± 4.6 minutes, respectively, which was significantly lower in the TPG group (P = 0.001). No nerve injuries, paresthesia, or other possible side effects were reported in patients.
According to the present study, it seems that TPG shows a faster sensory and motor block than SG.
在下肢手术中，周围神经阻滞因其便利性和患者良好的耐受性而被广泛接受。该方法对快速操作以及快速产生感觉和运动阻滞有较高要求。本研究旨在比较两种不同的坐骨神经和胫腓神经阻滞方法在下肢手术中的阻滞起效时间。
在这项临床试验中，52例择期下肢手术患者被随机分为两组：在超声和神经刺激器引导下，坐骨神经分叉前阻滞组（SG组；n = 27）和胫腓神经分别阻滞组（TPG组；n = 25）。记录并比较两组的平均阻滞操作时间以及完全感觉和运动阻滞的时间。
SG组和TPG组完全感觉阻滞的平均时间分别为35.4 ± 4.1分钟和24.9 ± 4.2分钟，TPG组明显更低（P = 0.001）。SG组和TPG组完全运动阻滞的平均时间分别为63.3 ± 4.4分钟和48.4 ± 4.6分钟，TPG组明显更低（P = 0.001）。患者未报告神经损伤、感觉异常或其他可能的副作用。
根据本研究，TPG组似乎比SG组表现出更快的感觉和运动阻滞。
