Efficacy and Safety of Ultrasound Guided Inter-semispinal Plane Block for Postoperative Analgesia in Posterior Cervical Laminectomy - A Prospective Randomised Controlled Study.

Study Design: Prospective, randomized controlled study.

Objective: To assess the safety and efficacy of an ultrasound-guided ISP block for postoperative analgesia in posterior cervical laminectomy.

Methods: 88 patients requiring posterior cervical laminectomy were randomized into two groups, those who underwent ISP block with multimodal analgesia (ISPB group) and those with only multimodal analgesia (control group).

Clinical efficacy of ultrasound guided bilateral erector spinae block for single-level lumbar fusion surgery: a prospective, randomized, case-control study.

Background Context: Postoperative experience plays a vital role in patient recovery and does not depend on the type and quality of the surgical procedure alone. Non-opioid therapies have become part of the multimodal analgesic regimen for better pain control and reduced opioid-related side effects. Most recently evolved among these are the regional anesthetic techniques, such as the thoracolumbar interfascial plane (TLIP) block and the erector spinae (ESP) block.
