Infiltration of local anesthetic agents to achieve analgesia for the repair of lacerations or the excision of large lesions requires multiple injections, uses large volumes of local anesthetic solution and frequently produces inadequate pain relief. Peripheral nerve blocks utilize a small number of precisely placed injections to anesthetize relatively large areas of the body. Many of these blocks are safe and easy to perform in an outpatient setting.
浸润局部麻醉药以实现对撕裂伤修复或大病灶切除的镇痛,需要多次注射,使用大量局部麻醉溶液,且常常无法充分缓解疼痛。周围神经阻滞通过少量精准注射来麻醉身体相对较大的区域。其中许多阻滞操作在门诊环境中既安全又易于实施。
