Recto-intercostal Fascial Plane Block and Pecto-intercostal Fascial Plane Block for Cardiac Surgery

For RIFPB, a local anesthetic will be injected into the plane between the costal cartilage and the rectus abdominis muscle at the 6th-7th costal cartilage under US guidance. The in-plane technique will be used. After confirming the block location, 10 ml of 0.25% concentration marcaine (bupivacaine) will be used (bilateral).

"Patients will be administered 10mg/kg paracetamol in the postoperative period every eight hours.~If the NRS score is ≥ 4, 1 mg kg-1 iv tramadol will be administered as a rescue analgesic."

For PIFPB; the ultrasound probe for PIFB is placed 2-3 cm lateral to the upper third of the sternum, parallel to the sternum. A local anesthetic of 15 ml of 0.25% concentration of marcaine (bupivacaine) will be used between the pectoralis major and external intercostal muscles (bilateral).
