Comparison of the Efficacy of Thoracolumbar Interfascial Plane Block and Erector Spina Plane Block in Lumbar Discectomy

"Modified thoracolumbar plane block (mTLIP): under ultrasound-guided, the lateral compartment of the longissimus muscle and iliocostal muscle muscles are imagined and the block needle is placed in the interfascial plane of these two muscles and local anesthesic solution is appliced.~* 20 ml of 0.25% bupivacaine will be used on each side (total of 40 ml of 0.25% bupivacaine will be used)~* to be administered only approximately 20-30 minutes before the onset of anaesthesia."

"Erector spinae plane block (ESP): After determining the vertebral spinal process and trapezius, rhomboid major and erector spinae muscles with ultrasound guidance, the block needle is advanced in the cranio-caudal direction with an in plane approach and local anaesthetic solution is applied to the plane between the erector spinae muscle and the transverse process when the needle rests on the transverse process.~* 20 ml of 0.25% bupivacaine will be used on each side (total of 40 ml of 0.25% bupivacaine will be used)~* to be administered only approximately 20-30 minutes before the onset of anaesthesia"
