Erector Spinae Plane Block and Subcostal Transverse Abdominis Plane Block in Laparoscopic Cholecystectomy

Evaluation of Postoperative Analgesic Effect of Ultrasound Guided Erector Spinae Plane Block and Subcostal Transverse Abdominis Plane Block in Laparoscopic Cholecystectomy, Randomised Controlled Study

Erector Spinae Plane Block is a newly defined regional anesthesia technique. Its use for many indications has been identified by case reports in the literature. As the investigators have considered that erector spinae plane block could be efficacious for providing postoperative analgesia in laparoscopic cholecystectomy, the investigators have implemented the application of this blockade into practice at the clinic Subcostal transverse abdominis plane block (STAP) is another regional anesthesia technic used for postoperative analgesia in laparoscopic cholecystectomy. Main purpose of this study is to compare the analgesic effect of ultrasound-guided erector spinae block and STAP in laparoscopic cholecystectomy.
