简要总结
Surgical procedures on the spine often result in significant postoperative pain, with inadequate pain control affecting recovery and increasing chronic pain risk. Traditionally, opioids have been used for pain management, but ERAS protocols encourage a multimodal approach to reduce opioid reliance. Regional anesthesia techniques, particularly peripheral nerve blocks like the erector spinae plane (ESP) block and retrolaminar (RL) block, are gaining attention for their effectiveness and fewer side effects compared to neuraxial methods. The ESP block targets spinal nerve rami and sympathetic nerves, while the RL block focuses on dorsal rami. Both techniques have shown promise in reducing pain and opioid consumption, but more comparative studies are needed to determine the best option for postoperative analgesia in spine surgery.
In the present study, patients will be randomly assigned to receive either a Retrolaminar block (RL) or an Erector Spinae Plane block (ES). Patients will undergo routine evaluations and fasting protocols. In the operating room, ASA standard monitors will be attached, induction of anesthesia will be performed, and the allocated block will be performed using ultrasound guidance after placing the patients in the surgical position (prone).
Group ‘RLB’ (Retrolaminar Block )- All patients will receive ultrasound (US) guided Retrolaminar block with 15 mL of 0.375% Ropivacaine on either side.
Group ‘ESPB’(Erector Spinae Plane Block)-All patients will receive ultrasound guided Erector Spinae Plane Block with 15 ml of 0.375% Ropivacaine on either side.
Block performance time, number of attempts, and complications will be recorded. Anesthesia maintenance will include isoflurane and rocuronium, with intraoperative analgesia provided by fentanyl and paracetamol. Postoperative pain will be assessed using a numerical rating scale (NRS), and rescue analgesia will be administered as needed. Side effects and patient satisfaction will also be documented throughout the study period.
