7 – How to perform the classic TAP plexus block

Lower abdomen (Th10-Th12/L1) – the classic TAP block: Place the transducer above the iliac crest and below the thoracic cage

Identify the external and internal oblique muscles and the underlying transversus abdominis muscle

The needle insertion point on the skin should be in the anterior axillary line.

Insert the needle in-plane to the transducer and advance in a lateral and posterior direction

The end-point will be in the neurovascular fascial plane between the internal oblique muscle and the transversus abdominis muscle

Inject 15 ml ropivacaine 0.375% at each of the four points of the BD-TAP block (for adults)
