Abstract：
OBJECTIVE: Rebound pain (RP) is a common occurrence after peripheral nerve block placement, especially when blocks are used for orthopedic surgery. This literature review focuses on the incidence and risk factors for RP as well as preventative and treatment strategies.
RESULTS: The addition of adjuvants to a block, when appropriate, and starting patients on oral analgesics prior to sensory resolution are reasonable approaches. Using continuous nerve block techniques can provide extended analgesia through the immediate postoperative phase when pain is the most intense. Peripheral nerve blocks (PNBs) are associated with RP, a frequent phenomenon that must be recognized and addressed to prevent short-term pain and patient dissatisfaction, as well as long-term complications and avoidable hospital resource utilization. Knowledge about the advantages and limitations of PNBs allows the anesthesiologists to anticipate, intervene, and hopefully mitigate or avoid the phenomenon of RP.

摘要：
目的：周围神经阻滞放置后，反弹疼痛（RP）是常见的，尤其是当骨块用于矫形外科手术时。本文综述了RP的发生率和危险因素以及预防和治疗策略。
结果：向嵌段添加佐剂，在适当的时候,在感觉消退之前开始患者口服镇痛药是合理的方法。使用连续神经阻滞技术可以在疼痛最剧烈的术后即刻提供延长的镇痛。周围神经阻滞（PNBs）与RP有关，必须认识和解决这种常见现象，以防止短期疼痛和患者不满，以及长期并发症和可避免的医院资源利用。关于PNB的优势和局限性的知识允许麻醉师预测，干预,并希望减轻或避免RP现象。
