Regional Anesthesia for Ambulatory Anesthesiologists

Key points
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.

2022, Journal of Plastic, Reconstructive and Aesthetic SurgeryCitation Excerpt :In BRM, preoperative nerve blocks have been found to significantly decrease intraoperative opioid administration, postoperative nausea, and vomiting, and patient-reported pain when first awakening from anesthesia.12 Furthermore, erector spinae nerve blocks are easy to administer using ultrasound guidance and are considered very safe, with no major reported complications apart from a single reported case of pneumothorax.11,13–15 However, no studies have evaluated yet the role of peripheral nerve blocks in reducing postoperative opioid consumption in BRM.
