Zusammenfassung:Prospective, randomized controlled study. To assess the safety and efficacy of an ultrasound-guided ISP block for postoperative analgesia in posterior cervical laminectomy. 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). Demographic details, intraoperative parameters (blood loss, duration of surgery, perioperative total opioid consumption, muscle relaxants used), and postoperative parameters (numeric rating scale, satisfaction score, mobilization time, and complications) were recorded. The total opioid consumption (128.41 + 39.65vs 284.09 + 140.92mcg; < .001), muscle relaxant usage (46.14 + 6.18 mg vs 59.32 + 3.97 mg; < .001), surgical duration (128.61 + 26.08/160.23 + 30.99mins; < .01), and intra-operative blood loss (233.18 + 66.08 mL vs 409.77 + 115.41 mL; < .01) were significantly less in the ISPB group compared to the control. In the postoperative period, the control group's pain score was significantly higher ( < .001) in the initial 48 hours. The Modified Observer Alertness/Sedation Score (MOASS) score and satisfaction scores were significantly better in the ISPB compared to the control ( < .001). The mean time required to ambulate was statistically less in ISPB (4.30 + 1.64hours) when compared to controls (9.48 + 3.07hours) ( < .001). In patients undergoing posterior cervical laminectomy, ISP block is a safe and effective technique with better outcomes than standard multi-modal analgesia alone, in terms of reduced intra-operative opioid requirements and blood loss, better postoperative analgesia, and early mobilization.
