Ultrasound-guided regional anesthesia alleviates pain after percutaneous liver biopsy / 中华全科医师杂志

ABSTRACT

The aim of this study is to evaluate the application of untrasound-guided local anesthesia in alleviation of pain after percutaneous liver biopsy.The clinical results of 1417 cases of percutuneous liver biopsy were retrospectively analyzed.In 896 patients under ultrasound-guided local anesthesia 51 felt pain after liver biopsy,while in 521 patients whose local anesthesia without ultrasound guidance,143 felt pain (5.7% vs.27.4%,X~2=118.63,P＜0.01).The results indicate ultrasound-guided local anesthesia can effectively alleviate pain after percutaneous liver biopsy.
