Transversus abdominis plane block: what is its role in postoperative analgesia?
| The first 10% of the full text of this article appears below. |
Over the past 3 yr, a series of studies have highlighted the value of the transversus abdominis plane (TAP) block, after the initial description of the technique by Rafi.1 The technique involves injection of local anaesthetic solution into a plane between internal oblique (IO) and transversus abdominis (TA) muscles. This plane contains the thoracolumbar nerves originating from T6 to L1 spinal roots which supply sensation to the anterolateral abdominal wall. These multiple mixed segmental nerves branch and communicate as they run through the lateral abdominal wall between IO and TA muscles, within the TA fascial plane.2
The TAP block is performed usually
