AbstractRegional anesthetic techniques are important components of successful multimodal analgesic strategies. When used successfully, truncal nerve blocks of the chest wall, abdomen, and, paraneuraxial nerves, in combination with other analgesic modalities, may offer similar analgesic efficacy as neuraxial techniques, which are associated with a greater risk profile. Moreover, in comparison to neuraxial techniques, truncal nerve blocks are relatively simple to perform and technically straightforward to learn. The transversus abdominus plane (TAP) block is often incorporated into the multimodal analgesia regimen for surgical patients undergoing various abdominal and gynecological procedures. Rectus sheath blocks (RSB) were originally introduced to help relax the anterior abdominal wall during surgery and as an adjunct pain therapy. With the advancement of technology and the development of ultrasound guided techniques, RSB now have a more ubiquitous role and have been shown to decrease postoperative pain and opioid consumption. Different variations of the quadratus lumborum block may provide visceral and sensory analgesic coverage. Moreover, truncal blocks, including ilioinguinal, iliohypogastric, pectoralis nerve (PECS) blocks, serratus anterior, intercostal, and erector spinae plane blocks, have gained routine clinical use for various surgeries. In this review, we discuss the techniques, anatomy, indications, complications, and benefits of truncal nerve blocks commonly used in clinical practice.Published by Elsevier Ltd.
