Has the future arrived? Liposomal bupivacaine versus perineural catheters and additives for interscalene brachial plexus block.
Abstract
Single injection interscalene block (ISB) provides effective analgesia for shoulder surgery. However, the duration of these is limited. This review summarizes the effectiveness of three potential means of extending the duration of analgesia: perineural infusion of local anesthetic agents, addition of adjuvant drugs to local anesthetics in single-injection nerve block, and utilization of liposomal bupivacaine in the surgical field or in the block itself.
