Overview

Patients will be called to the operating room one hour before surgery and no premedication will be applied before coming to the operating room. Patients in both groups who are taken to the block room will be administered 1-2 mg iv midazolam for sedation. M TAPA block will be applied for the surgical procedure. After aseptic conditions are provided, the high-frequency linear US probe will be covered with a sterile sheath. The US probe will be placed in the saggital plane at the costochondral angle where the midclavicular line intersects the costal cartilage. 5 ml of saline will be injected using the in-plane technique using a 22G 100 mm block needle and the block location will be verified. After the block location is verified, a total of 20 ml of 0.25% bupivacaine will be injected unilaterally and the procedure will be terminated. After aseptic conditions are provided, the high-frequency linear US probe will be covered with a sterile sheath. In TAP block, the block needle will be advanced to the fascial plane between the internal oblique and transversus abdominis muscles with the in-plane technique and the procedure will be completed by injecting 5 ml 20 ml 0.25% bupivacaine unilaterally. The same analgesia protocol will be applied to both groups intraoperatively and postoperatively, and a survey will be conducted on the patients at the 24th hour postoperatively.
