Evaluation of Thoracolumbar Interfascial Plane Block for Postoperative Analgesia After Herniated Lumbar Disc Surgery

Several regional anesthesia have been shown to improve postoperative outcomes in many studies. The transversus abdominis plane (TAP) block provides anesthesia to the abdominal wall by introducing local anesthetic to the anterior rami of the spinal nerve roots. This work evaluates the analgesic effects gained after performing thoracolumbar interfacial plane block (analogous to the TAP block but intended for the back) which targets the sensory component of the dorsal rami of the thoracolumbar nerves in patients undergoing back surgeries.
