Nerve Block Gallery - Transversus Abdominis Plane Block
Caption
A transversus abdominis block is shown, with the needle approaching in plane, passing through the external oblique muscle superficially, then the internal oblique muscle in the middle, and depositing anesthetic in the fascial plane below the internal oblique muscle and superficial to the transversus abdominis muscle. This nerve block provides anesthesia of the hemi-abdomen and is useful in providing analgesia for conditions like appendicitis or diverticulitis.
