Comparison of dermatomal sensory block following ultrasound-guided transversus abdominis plane block by the lateral and posterior approaches: A randomized controlled trial
Key Take-Away:
This study explained that the Posterior approach TAP block (PTAP) provided a sensory block that involved a greater number of dermatomes and involvement of more cephalad dermatome blocked to sharp touch as compared to the Lateral approach TAP block (LTAP) under US guidance. The posterolateral spread of the local analgesic agent to the paravertebral space might be linked to the high number of dermatomes.
Ultrasound (US)-guided transversus abdominis plane (TAP) block is used as a part of a multimodal analgesic regimen in the postoperative period.
