简要总结
This is a randomized comparative study to compare the incidence of hemidiaphragmatic paresis and analgesic efficacy after Ultrasound guided interscalene brachial plexus, anterior suprascapular and posterior suprascapular nerve block in patients undergoing arthroscopic shoulder surgery under general anaesthesia with the hypothesis that the incidence of hemidiaphragmatic paresis is less after posterior approach of suprascapular nerve block as compared to anterior approach of suprascapular nerve block and interscalene brachial plexus block plexus in patients undergoing arthroscopic shoulder surgery while providing noninferior analgesia.
Primarily hemidiaphragmatic paresis is determined by Forced expiratory volume in first second, Forced vital capacity and diaphragmatic excursion at pre-block, post-block 30 minutes and 1st hour post-operatively. Secondarily analgesic efficacy is compared with regards to 1)Total fentanyl requirements during intraoperative period. 2)Numerical rating scale (NRS) pain score. 3)Time taken to first rescue analgesia demand. 4)Total tramadol consumption during first 24 hours of postoperative period. Numerical rating scale (NRS) pain score is measured at immediate post-operatively, 1st hour post-operatively, 6th hour post-operatively, 12th hour post-operatively and 24th hour post-operatively.
