Transversus Abdominis Plane Block Versus Paravertebral Block for Post Operative Pain Relief in Open Renal Surgeries

Thoracic paravertebral block is a technique in which , the local anesthetic agent is injected in the paravertebral space to anesthetise the spinal nerves after emerging from the vertebral canal in order to provide analgesia in the thoracic and upper abdominal area .

Transversus abdominis plane block is a technique is mostly done under ultrasound guidance to identify the transversus plane between the internal oblique muscle and the transverses abdominis muscle , the space in which the neurovascular supply of the anterior abdominal wall is present , and hence the injection of local anesthetic agent in this space results in anesthesia of the anterolateral aspect of the abdominal wall.
