The Effect of Ultrasound-guided Erector Spinae Plane Block on Postoperative Analgesia in Radiofrequency Ablation Therapy

• Status: Recruiting
• Trial end date: 2022-02-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a double blind, randomized controlled trial to evaluate the efficacy of ESPB(Erector Spinae Plane Block) on postoperative analgesia in RFA( Radiofrequency Ablation therapy). We will include 80 patients, and randomly assign to ESPB(Chirocaine) group and control group(normal saline).We deduce Erector spinae plane block can be use as a postoperative analgesic way for patients who receive radiofrequency ablation of hepatocellular carcinoma.

• Phase: N/A
• Accepts Healthy Volunteers?: No
