Rhomboid Intercostal and Subserratus Plane Block

Study Overview
=================
Brief Summary
-----------------
Laparoscopic surgery is frequently used today for abdominal region operations. Laparoscopy has become the preferred treatment for cholecystectomy. Patients undergoing laparoscopic cholecystectomy suffer from acute postoperative pain despite the multimodal analgesic regimen. For this type of surgery, many different field blocks have been used for postoperative analgesia.

Detailed Description
-----------------
In this study, the analgesic efficacy of Unilateral Rhomboid intercostal and subserratus block was investigated in patients who had laparoscopic cholecystectomy.
