Transforming Pediatric Thoracotomy: The Critical Role of Thoracic Paravertebral Block in Cyanotic Congenital Heart Disease

Abstract

Background: Cyanotic Congenital Heart Disease (CCHD) encompasses a range of cardiac anomalies that result in low oxygen levels in the blood. This case report explores the use of Thoracic Paravertebral Block (TPVB) as an effective anesthetic technique in a pediatric patient with multiple congenital heart defects.

Case Illustration : We report the case of a 46-day-old male pediatric patient diagnosed with CCHD, including pulmonary atresia and Transposition of the Great Arteries (TGA) with Ventricular Septal Defect (VSD) and Atrial Septal Defect (ASD). The patient had previously undergone a right Blalock-Taussig (R-BT) shunt and PDA stenting, during which he experienced cardiac arrest but achieved return of spontaneous circulation (ROSC). He was admitted for another operation, thoracotomy and decortication due to trapped pleural effusion and empyema. The intraoperative management included the use of TPVB, which provided effective analgesia and hemodynamic stability throughout the procedure.

Discussion: TPVB has been increasingly recognized as a valuable regional anesthetic technique in pediatric cardiac surgery. Its use can mitigate the hemodynamic fluctuations often seen with general anesthesia alone, especially in patients with compromised cardiovascular status. In this case, TPVB facilitated stable anesthesia, reduced the requirement for systemic opioids, and helped manage recurrent episodes of desaturation and bradycardia.

Conclusion: TPVB is a viable anesthetic option in pediatric patients with CCHD undergoing thoracic surgery. It offers substantial benefits in terms of hemodynamic stability and pain management, contributing to improved perioperative outcomes in this high-risk population
