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

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.

Inclusion Criteria:

• patients with ASA 1 or 2 aged between 21years old up to 60 years old of both sex scheduled of back surgery

Exclusion Criteria:

• Exclusion criteria will be patients refusal or inability to give an informed consent , history of relevant allergy to any of the drugs used in the procedure , previous lumbar spine surgery or back surgery with planed spinal fixation.
