The Analgesic Efficacy of Thoracolumbar Interfascial Plane block (TLIP) versus Erector Spinae Plane block (ESPB) for Thoracolumbarspine surgeries – A Randomised controlled study

Surgical management is commonly required for degenerative and traumatic disorders of the thoracolumbar spine, with postoperative pain presenting as a frequent and significant challenge. The erector spinae plane (ESP) block, involves injection of local anesthetic beneath the erector spinae muscle while  the thoracolumbar interfascial plane (TLIP) block targets the plane between the longissimus and multifidus muscles and primarily attenuates pain via blockade of the dorsal rami . Participants  will be divided into 2 groups - Group EP : All patients will receive standard general anaesthesia followed by bilateral Erector spinae block using 20 ml of 0.25% levobupivacaine with 1 ug/kg of dexmedetomidine. (20ml each side )Group TP : All patients will receive standard general anaesthesia followed by bilateral Thoracolumbar interfascial plane block using 20 ml of 0.25% levobupivacaine with 1ug/kg of dexmedetomidine . (20ml each side ) .primary and secondary outcomes will be measured at 2,6,12,24,4 hours .
