To compare the efficacy of ultrasound guided modified thoracolumbar Interfascial plane block and lumbar-erector spinae plane block in lumbar spine surgeries - A randomised comparative study

We aim to study and compare the efficacy of ultrasound guided modified thoracolumbar interfascial plane block and lumbar erector spinae plane block in lumbar spine surgeries. Patients will be divided into two groups with the help of the randomisation technique.

Patients falling under Group A will undergo a mTLIP block bilaterally with a dose of 0.5 percent ropivacaine 15 mL and 100 mcg dexmedetomidine on each side after induction of patient under general anaesthesia at IGMC,Shimla while patients belonging to Group B will receive Lumbar Erector Spinae Plane (L-ESP) block with of a mixture of 15 ml of 0.5 percent Ropivicaine and 100mcg dexmedetomidine on each side after induction with GA at IGMC, Shimla. After the completion of surgery the patient will be extubated and transferred to the post- anaesthesia care unit .At PACU ,the patient’s visual analog score (VAS) will be assesed . Time zero will be the pain status of the patient after shifting the patient to the Post anaesthesia care unit. Patient satisfaction score will be observed after a period of 48 hours and compared among the two groups.
