Recto-intercostal Block for Coronary Artery Bypass Grafting

After ensuring aseptic conditions, the high-frequency linear ultrasound probe was used to detect the rectus abdominis muscle and the 6-7th costal cartilage as described by Tulgar et al. After rotating and shifting the transducer, 6-7th costal cartilages, the rectus abdominis muscle, and intercostal muscles between the cartilages were confirmed. The primary investigator (B.C.) directed the needle tip caudad in the cephalic direction in-plainly, and 20 ml 0,25% bupivacaine was injected bilaterally into the plane between the costal cartilage and the rectus abdominis muscle following negative aspiration.
