About

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.

Full description

Computed tomography guided radiofrequency ablation of hepatocellular carcinoma(HCC) has became a popular way to treat HCC. Although the wound is small and the patients can discharge on the next day, they have to suffer from moderate to severe pain. Nowadays Erector spinae plane block has been applied to many surgery as a postoperative analgesic strategy. We deduce Erector spinae plane block can be use as a postoperative analgesic way for patients who receive radiofrequency ablation of hepatocellular carcinoma. Besides, we will add contrast medium to evaluate the spread area of local anesthetics.
