Serratus Posterior Superior Plane Block for Postoperative Pain in Cardiac Surgery
Sponsor: Ondokuz Mayıs University
Summary
The aim of this study is to investigate the efficacy of bilateral serratus posterior superior intercostal plane (SPSIP) block on postoperative acute pain and opioid consumption in patients undergoing on-pump open-heart surgery. Postoperative outcomes including pain scores, cumulative morphine use, quality of recovery, and opioid-related side effects will be evaluated within the first 24 hours after surgery.

Interventions
Bilateral ultrasound guided Serratus Posterior Superior Plane Block
Bilateral ultrasound-guided Serratus Posterior Superior Plane Block (total of 60 ml, %0.25 bupivacaine) will be performed Multimodal analgesia : Intraoperatively, all patients will receive 0.05 mg/kg (IBW) iv morphine. Thirty minutes before the end of surgery, 1 gram of intravenous paracetamol will be administered. Postoperative analgesia: iv paracetamol 1gr every 8 hours and IV PCA of 0,5mg/ml morphine. In cases where rescue analgesia is required (NRS score ≥4),iv fentanyl 25-50 mcg and/or ibuprofen and/or ketamine 10 mg will be administered. Patients are routinely administered iv dexamethasone 4 mg and IV 8 mg ondansetron 20 minutes before end of surgery for postoperative nausea and vomiting prophylaxis.
IV morphine patient-controlled analgesia
IV PCA of 0,5mg/ml morphine (the bolus dose is 20 μg/kg, the lock-in time of 6-10 minutes, the 4-hour limit is adjusted to be 80% of the calculated total amount).
Bilateral ultrasound guided Sham Block
Bilateral ultrasound-guided needle placement will be performed in the same anatomical plane as in the SPSIP group, but instead of local anesthetic, an equivalent volume of normal saline (30 mL per side) will be injected. Multimodal analgesia : Intraoperatively, all patients will receive 0.05 mg/kg (IBW) iv morphine. Thirty minutes before the end of surgery, 1 gram of intravenous paracetamol will be administered. Postoperative analgesia: iv paracetamol 1gr every 8 hours and IV PCA of 0,5mg/ml morphine. In cases where rescue analgesia is required (NRS score ≥4),iv fentanyl 25-50 mcg and/or ibuprofen and/or ketamine 10 mg will be administered. Patients are routinely administered iv dexamethasone 4 mg and IV 8 mg ondansetron 20 minutes before end of surgery for postoperative nausea and vomiting prophylaxis.
