This study investigated the use of a continuous parasacral sciatic nerve block for anesthesia and postoperative analgesia for lower extremity surgery.
A continuous parasacral sciatic nerve block was performed in two patients (triple ankle arthrodesis and below-knee amputation). The sacral plexus was identified using an insulated Tuohy needle and a nerve stimulator. A catheter was placed near the elements of the sacral plexus via the Tuohy needle.
In both patients, surgical anesthesia was successfully established through the parasacral catheter with lidocaine 1% (1/200,000 epinephrine), and postoperative analgesia was successfully established with a bolus of bupivacaine 0.375% (1/200,000 epinephrine) and maintained with a continuous infusion of bupivacaine 0.1% (8 mL/h) for 48 hours.
We conclude that continuous parasacral sciatic nerve block can provide anesthesia and long-term analgesia for operative procedures of the foot and leg.
本研究探讨连续骶旁坐骨神经阻滞用于下肢手术麻醉及术后镇痛的效果。
对两名患者（三踝关节融合术和膝下截肢术）实施连续骶旁坐骨神经阻滞。使用绝缘的Tuohy针和神经刺激器识别骶丛。通过Tuohy针在骶丛周围放置一根导管。
两名患者均通过骶旁导管成功使用1%利多卡因（1/200,000肾上腺素）建立手术麻醉，术后通过推注0.375%布比卡因（1/200,000肾上腺素）成功建立镇痛，并通过持续输注0.1%布比卡因（8毫升/小时）维持48小时。
我们得出结论，连续骶旁坐骨神经阻滞可为足部和腿部手术提供麻醉和长期镇痛。
