Comparative study of the efficacy of ultrasound-guided erector spinae block and oblique subcostal transversus abdominis plane block for postoperative analgesia after laparoscopic cholecystectomy

Abstract Background Laparoscopic cholecystectomy has changed the surgical management of cholelithiasis and become mainstay uncomplicated gallstone disease. Adequate postoperative pain relief leading to early ambulation is imperative for patient satisfaction discharge patient. The use ultrasound in anesthetic practice ushered a new era ultrasound-guided blocks analgesia, replacing conventional methods. This study compares two modalities relief, namely oblique subcostal transversus abdominis plane block newer erector spinae patients undergoing laparoscopic cholecystectomy. Results Sixty between age group 18 75 ASA grades I, II, III were enrolled study. showed lower numerical rating scores up 12 h, longer time period requirement first rescue analgesic, total analgesic consumption postoperatively compared group. Both found have minimal side effects. Conclusions superior that it affords duration analgesia reduces after Trial registration Clinical Trials Registry India/CTRI/2020/10/028603/ registered on 23 October 2020 http://ctri.nic.in/Clinicaltrials/rmaindet.php?trialid=47807&EncHid=18303.55562&modid=1&compid=19
