Is ESPB not inferior to PVB considering postoperative opioid consumption ? Researchers will compare the opioid consumption 24h postoperatively among the patients remaining supine, lateral, prone position after ESPB and PVB to see if patients maintaining lateral or prone position provided excellent postoperative analgesia.\n\nParticipants will:\n\nMaintaining supine lateral or prone position for 30 min following ESPB or receiving PVB.\n\nReceiving postoperative NRS and QoR assessment",[81],"Erector Spinae Plane Block",[83,84,85,86],"Paravertebral thoracic block","Clinical application","Perioperative analgesia","Erector spinae plane block","2025-07-17",{"date":89,"type":90},"2025-07-21","ACTUAL",{"date":92,"type":90},"2024-06-14",{"date":94,"type":75},"2026-12-01",{"name":5,"class":6},1]
