The abdominal wall and peritoneum are innervated by thoracolumbar nerves T6 to L1. Transversus abdominis plane (TAP) block provides analgesic benefits by blocking the transmission of pain from these nerves. Ultrasound landmarks include the external oblique, internal oblique, and transversus abdominis muscles. TAP blocks should be considered for patients in which neuraxial technique is contraindicated for abdominal surgical procedures including cesarean delivery. There are multiple benefits to TAP blocks when performed for the appropriate patient and correctly. Risks associated with the procedure include infection, hematoma, peritoneal perforation, bowel puncture, and local anesthetic toxicity.
