The innervation of the anterior abdominal wall comes from nerve afferents from T6-L1 running in the neurovascular plane which is found between internal oblique and transversus abdominis (TA). The transversus abdominis plane (TAP) block aims to block these nerves with local anaesthetic before they pierce the anterior abdominal wall. It has already shown to be effective in reducing pain in the first 24 hours after a laparotomy when compared to PCA with opiates and shown to have potential in a series of patients undergoing radical prostatectomy.
