Key points

  • Regional anesthesia can enhance postoperative pain control and perioperative outcomes in an ambulatory surgical setting.

  • Many surgeries commonly performed in ambulatory surgical centers are amenable to nerve blocks.

  • Proper needling technique, discussed in this article, helps minimize risk of adverse events.

Interscalene Brachial Plexus Block

The interscalene block (ISB), which is performed at the level of the roots, encompasses mainly C5 to C7 blockade and can involve C3 to C4. Benefits of ISB include potential avoidance of volatile anesthetics, reduced opioid consumption and opioid-related side effects, fewer awakenings from pain, and improved postoperative analgesia and rehabilitation.2, 4 In patients undergoing rotator cuff repair, continuous interscalene block has shown improved analgesia and reduced opioid requirements

Paravertebral Block

Paravertebral nerve blocks (PVBs) present an opportunity to block multiple mixed nerve roots soon after they emerge from the intervertebral foramina, thus delivering analgesia that follows a dermatomal distribution. The paravertebral space is a wedge-shaped anatomic compartment adjacent to the vertebral bodies. The space is defined anterolaterally by the parietal pleura; posteriorly by the superior costotransverse ligament (thoracic levels); medially by the vertebra, vertebral disk, and

Femoral Block

Blockade of the femoral nerve results in sensory deficit to the anterior medial thigh and medial leg to the foot. Motor blockade involves the muscles of the anterior thigh, including the vastus medialis, vastus lateralis, and vastus intermedius, along with the sartorius muscle and rectus femoris. A femoral nerve block can result in significant weakness of the quadriceps.

Summary

Regional anesthesia can provide extensive benefits for ambulatory surgical patients. Proper regional anesthetic techniques can maximize patient comfort, promote postoperative discharge, and form an integral part of an effective and efficient perioperative practice. Knowledgeable and skilled anesthesiologists performing regional anesthesia can be the driving force behind excellence in patient satisfaction at ambulatory surgical centers.
