Evaluation of ultrasound-assisted thoracic epidural anesthesia in reducing postoperative pain in patients undergoing upper abdominal surgery: A randomized controlled trial
Main Article Content
Abstract
This study evaluated whether ultrasound-assisted thoracic epidural anesthesia (TEA) would be more effective in reducing postoperative pain than conventional thoracic epidural anesthesia based on anatomical markings. This randomized controlled study enrolled 63 patients undergoing upper abdominal surgery at Hanoi Medical University Hospital from April to August 2018. The patients were randomized into one of two groups : group I (n = 31) received ultrasound-assisted TEA and group II (n = 32) received conventional TEA.The results showed that the proportion of equivalence between localization of the thoracic epidural space based on ultrasound and anatomical markings was 63.3%. Group I had fewer occurences of percutaneous needle puncture and displacement of the thoracic intervertebral spaces, higher rate of successful TEA after the first puncture, and lower level of postoperative pain compared to group II. Our study suggested that ultrasound-assisted TEA had better results than conventional TEA based on anatomical markings.
