Continuous peripheral nerve block has been shown to be superior to traditional opioid-based analgesia in terms of improved analgesia with reduced sedation, nausea, pruritis, and hospital stay. Because of its safety and efficacy, continuous peripheral nerve block has broad application in ambulatory and pediatric patients. Techniques for continuous peripheral nerve block have advanced significantly in the past decade, particularly as a result of affordable, high-resolution ultrasound equipment that permits rapid and successful administration and results in reduced procedure-related pain, lower dose requirements, and fewer vascular punctures. Continuous peripheral nerve block is associated with some limitations, including infection, neurologic injury, local anesthetic toxicity, and patient falls. The benefits of continuous peripheral nerve block are becoming increasingly relevant in the ambulatory surgery setting where more complex procedures are being performed on an outpatient basis.
连续外周神经阻滞已被证明在改善镇痛效果方面优于传统的基于阿片类药物的镇痛方法，同时可减少镇静、恶心、瘙痒和住院时间。由于其安全性和有效性，连续外周神经阻滞在门诊患者和儿科患者中具有广泛应用。在过去十年中，连续外周神经阻滞技术取得了显著进展，特别是由于价格合理、高分辨率的超声设备，该设备允许快速且成功地给药，并减少了与操作相关的疼痛、降低了剂量需求以及减少了血管穿刺次数。连续外周神经阻滞存在一些局限性，包括感染、神经损伤、局部麻醉药毒性和患者跌倒。在门诊手术环境中，连续外周神经阻滞的益处变得越来越重要，因为越来越多的复杂手术在门诊进行。
