Peripheral nerve blocks afford numerous benefits for lower extremity surgery. There is growing interest in continuous peripheral nerve blocks, mainly for treatment of postoperative pain, a field that represents a challenge to the anaesthesiologist. This paper seeks to review the efficacy of continuous lower limb blocks for postoperative pain relief. Not only do continuous peripheral nerve blocks afford specificity of analgesic area but current research has shown that they enhance postoperative analgesia and patient satisfaction. New techniques and devices are increasingly appearing, and catheters are constantly being developed and improved; an example being the stimulating catheter, which represents one of the newest advances in this area. The above techniques show that continuous postoperative analgesia with catheters in the lower extremities is not only possible, but indeed provides sustained effective postoperative analgesia, reduces use of opioids, and improves rehabilitation and patient well-being with minimal side-effects. These techniques could prove an alternative to postoperative pain treatment following ambulatory surgery.
外周神经阻滞对下肢手术有诸多益处。人们对连续外周神经阻滞的兴趣与日俱增，主要用于治疗术后疼痛，这一领域对麻醉医生来说是一项挑战。本文旨在综述连续下肢阻滞用于术后镇痛的疗效。连续外周神经阻滞不仅能使镇痛区域具有特异性，而且目前的研究表明，它们能增强术后镇痛效果并提高患者满意度。新技术和设备不断涌现，导管也在持续研发和改进；刺激导管就是该领域最新进展之一。上述技术表明，下肢留置导管进行术后持续镇痛不仅可行，而且确实能提供持续有效的术后镇痛，减少阿片类药物的使用，并在副作用最小的情况下改善康复情况和患者的健康状况。这些技术可能成为门诊手术后疼痛治疗的一种替代方法。
