Comparing The Effect of Adding Dexmedetomidine to Bupivacaine in Classical and Modified Thoracolumbar Interfascial Plane Block on Postoperative Pain in Patients Undergoing Lumbar Disc Surgeries

Spinal surgeries are frequently conducted to stabilize the vertebrae and discs of the spine. These surgeries typically require substantial manipulation of subcutaneous tissues, bones, and ligaments . Postoperative pain relates to mechanical irritation, compression, and postoperative inflammation. The uncontrolled pain could promote the development of chronic persistent pain and worsen independence, mood, and quality of life. Effective pain management facilitates early mobilisation and accelerates hospital discharge. this study aim to investigate the effectiveness of a mixture of dexmedetomidine and bupivacaine in classical thoracolumbar interfascial plane block compare to modified thoracolumbar interfascial plane block on postoperative pain in patients undergoing lumbar disc surgeries.
