Peripheral nerve blocks.
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.
