Comparison of thoracolumbar interfascial plane block with local anaesthetic infiltration in lumbar spine surgeries - A prospective double-blinded randomised controlled trial.

Background And Aims: Posterior lumbar spine fusion surgeries are associated with severe postoperative pain necessitating a multimodal analgesic regime. Wound infiltration with local anaesthetic is an accepted modality for postoperative analgesia in spine surgeries. Thoracolumbar interfascial plane (TLIP) block is a novel technique being evaluated for providing analgesia in lumbar spine surgeries.
