Regional Anesthesia - Transversus Abdominis Plane (TAP) Block for Regional Anesthesia of the Abdomen


Anatomy. The anterior abdominal wall receives sensory innervation from the anterior (ventral) rami of the T7–T12 and L1 spinal nerves. The terminal branches of these nerves travel through the lateral abdominal wall within the transversus abdominis plane (TAP), the fascial plane between the internal oblique and the transversus abdominis muscles. Of note, just deep to the transversus abdominis lies the transversalis fascia and parietal peritoneum.
