Quadratus Lumborum Block Type III Versus Type II Versus Transversus Abdominis Plane Block in Cesarean Section

The transversus abdominis plane block (TAPB) is administered between the internal oblique muscle and the transversus abdominis muscle in the fascial plane, directly pointing to the somatic nerves T6-L1 that run in this plane. In addition, meta-analyses demonstrate that it is an effective analgesic for somatic pain and diminishes opiate intake. It has been reported that TAPB is an efficient analgesic approach following cesarean section . The quadratus lumborum (QL) muscle block (QLB) is a fascial plane block as local anesthetic (LA) is introduced nearby to the QL muscle to numb the thoracolumbar nerves. QLB is categorized into four types according to drug administration location, I (lateral), II (posterior), III (anterior/transmuscular), and Intravenous, (intramuscular). QLB can effectively decrease both visceral and somatic pain by LA distribution to the thoracic paravertebral space (TPVS), as this block ensures effective pain control from the T7 to L1 dermatomes. QLB is one of the regional techniques that provides the greatest benefit in post-CS pain control, as it is progressively applied in obstetric anesthetic precise to improve analgesic results.
