Exploring the efficacy of ultrasound-guided lumbar erector spinae plane block for perioperative analgesia in percutaneous nephrolithotomy: Report of two cases

Erector spinae plane block (ESPB) is used to a great extent for perioperative analgesia. The ease of administering it, safety and the perioperative analgesia achieved make it a good addition to anesthetic plans. The reduction in opioid usage with the usage of regional analgesia techniques may aid in enhanced recovery; in addition, regional analgesia with this block provides excellent analgesia and better postoperative outcome as seen here in two cases who underwent percutaneous nephrolithotomy (PCNL). Single-shot ESPB was performed in two cases undergoing PCNL. We achieved stable hemodynamics throughout the procedure and a mean NRS of 1.8 for a duration of 18 h postsurgery in both cases, with faster mobilization and early discharge of the patients.
