Erector Spinae Plane Block for Postoperative Analgesia for Laparoscopic Cholecystectomy

Study Overview
=================
Brief Summary
-----------------
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 application of this blockade into practice at the clinic. Main purpose of this study is to evaluate the analgesic effect of ultrasound guided erector spinae block in laparoscopic cholecystectomy.
