Preoperative Block for Anterior Cervical Spine Surgery

The purpose of this clinical trial study is to compare the analgesic effects of ultrasound-guided intermediate cervical plexus block Versus cervical erector spinae block in patients undergoing anterior cervical spine surgery. * The main questions it aims to answer are: * The primary outcome will be recording postoperative pain intensity using Numerical Rating Scale (NRS). * The secondary outcomes will be measuring the performance time, onset of the sensory block, intraoperative fentanyl consumption, time to the first call for rescue analgesia (nalbuphine), postoperative total nalbuphine consumption, and postoperative complications such as nausea, vomiting, hypotension, and bradycardia. * We will compare two blocks to a placebo. * Participants will: * undergo ultrasound-guided intermediate cervical plexus block or cervical erector spinae block or a placebo * Be assessed for pain after 2 h, 4 h, 6 h, 12 h, and 24 h postoperatively
