Comparison of Paravertebral Block and Deep Parasternal Intercostal Plane Block in Cardiac Surgery

Sponsor: Gaziantep City Hospital

Summary

Median sternotomy is commonly used in cardiac surgery and is often associated with significant postoperative pain. Poor pain control after sternotomy may increase opioid use, delay mobilization, prolong extubation time, and contribute to respiratory complications and longer hospital stay. Regional analgesia techniques may help improve pain management and reduce opioid requirements after surgery. This study is a prospective, randomized, single-center clinical trial that will compare two ultrasound-guided regional analgesia techniques in adult patients undergoing elective cardiac surgery through median sternotomy: thoracic paravertebral block and bilateral deep parasternal intercostal plane block. A total of 80 patients will be randomly assigned in a 1:1 ratio to receive one of these two blocks in addition to standard general anesthesia and routine multimodal analgesia. The main objective of the study is to compare the effects of these two techniques on total opioid consumption during the first 24 hours after surgery. Secondary outcomes include postoperative pain scores, need for additional analgesics, analgesia-related side effects such as nausea, vomiting, or respiratory depression, and extubation time. Pain will be assessed using a visual analog scale at predefined time points during the first 24 postoperative hours. The study hypothesis is that there will be a clinically meaningful difference in postoperative analgesic effectiveness between thoracic paravertebral block and bilateral deep parasternal intercostal plane block in patients undergoing cardiac surgery via median sternotomy. The results of this study may help guide the selection of the most appropriate regional analgesia technique for pain control after sternotomy.
