Ultrasound Guided Bilateral Pectoral Nerve Block Versus Bilateral Transverse Thoracic Plane Block In Pediatric Patients Undergoing Corrective Cardiac Surgeries Requiring Cardiopulmonary Bypass Via Median Sternotomy

This randomized, double-blinded, study aims to compare the efficacy of intraoperative and postoperative pain control while using bilateral ultrasound guided the pectoral nerves (PECS) versus transversus thoracic muscle plane block (TTPB) in pediatric patients undergoing corrective cardiac surgeries.

Good perioperative analgesia in cardiac surgical patients helps early recovery, ambulation, and early discharge from the Intensive Care Unit (ICU). Traditional use of nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids associated with adverse effect commonly used for pain control postoperative. The transversus thoracic muscle plane block (TTPB) is a recently advised regional anesthesia method that provides analgesia to the anterior chest wall and was initially introduced by Ueshima et al. in 2015 . The pectoral nerves (PECS) block has evolved to be two different types: PECS I and PECS II. In PECS I block, anesthetic is injected in the interfacial plane between the pectoralis major and minor muscles at the 3rd rib, blocking the lateral and medial pectoral nerves. The PECS II block, which was also developed by Blanco in 2012. The PECS block has been well established for its use in breast surgery for the adult population. , However, there has been a recent push in the last couple of years to find more about other uses for these types of blocks, especially in cardiac surgeries.
