Evaluation of the effect of different block techniques on open-heart surgery in the postoperative period: a prospective observational study

Background: Open-heart surgery is associated with severe postoperative pain. Adequate analgesia after open-heart surgery improves patients??? early postoperative recovery, extubation, ambulation and early discharge from hospital. Regional anaesthesia techniques are the new hope for adequate postoperative analgesia after cardiac surgery and are widely used for early pain management in the first six hours. Methods: A total of 100 patients with the American Society of Anesthesiologists physical status classification I???III, aged 18 years and over, undergoing open-heart surgery with sternotomy for coronary artery bypass grafting or valve replacement under general anaesthesia, were included in this study. For postoperative analgesia, 50 patients with pectoral nerve (PECS II) block and 50 with parasternal (PS) block were total morphine consumption and complications.
