Evaluation of Serratus Posterior Superior Intercostal Plane Block for Postoperative Analgesia in a Patient With Thoracal Spinal Tumor: Two Case Series.

Postoperative pain management is crucial for enhancing recovery and minimizing complications after spinal tumor resections. This case series evaluates the serratus posterior superior intercostal plane (SPSIP) block for postoperative analgesia in 2 patients undergoing thoracic spinal tumor surgeries. Bilateral SPSIP blocks were performed under ultrasound guidance, providing analgesia that specifically covered the levels where the tumor resection was performed. Numerical rating scale (NRS) scores remained low, with minimal opioid consumption and no adverse effects. The findings highlight the efficacy, safety, and opioid-sparing potential of SPSIP block as a novel regional anesthesia technique, emphasizing its utility in managing postoperative pain for thoracic spinal surgeries. Further studies are warranted. .
