Recto-intercostal Block for Coronary Artery Bypass Grafting

Condition(s) studied

Investigational drug(s) / intervention(s)

The recto intercostal fascial plane block: 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.

Study summary

This interventional study aims to learn about the postoperative analgesic efficacy of a new fascial plane block, recto-intercostal fascial plane block, at coronary artery bypass grafting with sternotomy. There will be two groups, one of which will be the control group, and the other will be the study group randomly receiving postoperative recto-intercostal fascial plane block.

The main questions it aims to answer are the effect of this new block on postoperative opioid consumption and pain scores. Also, postoperative outcomes related to respiratory ( postoperative oxygenation and atelectasis score), hemodynamic functions ( newly developed arrhythmias), total postanesthesia care unit stay, and hospital stay will be questioned.

Eligibility

Primary outcome measure(s)

• Total rescue analgesic — postoperative 24 hour
  . From the beginning of acclaimed arousal till the 24th hour, rescue analgesia as tramadol 100 mg (maximum daily dose 400 mg) is applied if NRS over 4 or with the patient's request.
