The results of the analgesic block of the lower extremity by means of an anterior (150 patients) or a posterior (114 patients) approach to the sciatic nerve, associated to a "3 in 1 block" were compared. The anterior approach technique was associated with a higher incidence of failures, insufficient analgesia and hence a higher demand for intraoperative analgesic and sedative drugs. Also tolerance to a pneumatic tourniquet over the proximal thigh was less than with the posterior approach. However, the sciatic nerve block by anterior approach granted a more prolonged analgesia. This technique was suitable for trauma patients immobilized in the supine position, for patients with skeletal traction on Zupinger frame, both for surgery and for closed reduction of lower extremity fractures.
比较了通过坐骨神经前入路（150例患者）或后入路（114例患者）联合“三合一阻滞”进行下肢镇痛阻滞的结果。前入路技术失败率更高、镇痛不足，因此术中对镇痛和镇静药物的需求量更大。此外，大腿近端对充气止血带的耐受性也低于后入路。然而，前入路坐骨神经阻滞的镇痛时间更长。该技术适用于仰卧位固定的创伤患者、在祖平格架上进行骨骼牵引的患者，适用于手术以及下肢骨折的闭合复位。
