Parasternal and Adductor Canal Blocks in CABG
Sponsor: Zonguldak Bulent Ecevit University
Summary
This randomized controlled trial evaluates the effectiveness of different postoperative analgesic strategies in patients undergoing coronary artery bypass graft (CABG) surgery. Patients were allocated into three groups receiving either conventional analgesia alone, parasternal block in addition to conventional analgesia, or combined parasternal and adductor canal blocks with conventional analgesia. The study aims to compare postoperative pain scores, opioid consumption, and recovery outcomes among the groups in order to determine whether the addition of regional anesthesia techniques, particularly the combined block approach, provides superior analgesia and enhances postoperative recovery following CABG surgery.

Interventions
parasternal block
Ultrasound-guided parasternal block was performed bilaterally after induction of general anesthesia in patients undergoing coronary artery bypass graft surgery. Following aseptic skin preparation, a high-frequency linear ultrasound probe was placed parallel to the sternum to identify the parasternal intercostal plane. A block needle was advanced under ultrasound guidance, and local anesthetic was injected into the interfascial plane adjacent to the sternum to provide anterior thoracic wall analgesia. The procedure was performed according to institutional standardized block protocols.
Parasternal block + Adductor canal block
In addition to conventional analgesia, patients received ultrasound-guided bilateral parasternal block and adductor canal block after induction of general anesthesia. The parasternal block was performed by injecting local anesthetic into the interfascial plane adjacent to the sternum under ultrasound guidance to provide anterior thoracic wall analgesia. The adductor canal block was performed under ultrasound guidance by depositing local anesthetic within the adductor canal to provide analgesia at the saphenous vein graft harvesting site. All procedures were performed according to standardized institutional protocols.
conventional analgesic regimen
Patients received standard postoperative analgesia consisting of intravenous patient-controlled analgesia (PCA) with morphine following coronary artery bypass graft surgery. The PCA device was initiated in the postoperative period according to institutional analgesia protocols, allowing patient-administered morphine dosing for pain control. Additional rescue analgesics were administered when clinically indicated.
