The Role of the Anesthesiologist in Pediatric Intensive Care Unit: A Narrative Review

Background: The Pediatric Intensive Care Unit (PICU) manages critically ill neonates, infants, and children with complex physiological derangements. Anesthesiologists, by virtue of their specialized training in pediatric physiology, pharmacology, airway management, and perioperative medicine, are uniquely positioned to contribute to high-quality PICU care. Methods: This narrative review synthesizes evidence from major anesthesiology and critical care journals to evaluate the role of Anesthesiologists in the PICU. The review focuses on key domains of pediatric critical care practice in which Anesthesiologists have substantial impact, including airway management, mechanical ventilation, hemodynamic support, sedation and analgesia, and perioperative critical care encompassing both intraoperative and postoperative management. In addition, the review highlights the role of Anesthesiologists in multidisciplinary leadership, emphasizing their contribution to team coordination, protocol implementation, and overall quality of care in the PICU setting. Results: The literature consistently demonstrates that Anesthesiologist involvement in the PICU is associated with significant improvements in multiple clinical domains. These include enhanced airway safety through advanced airway management skills; optimized ventilation strategies tailored to pediatric patients—particularly in hypoxemic and hypercapnic respiratory failure—and improved pain and sedation control through individualized pharmacologic approaches. Furthermore, Anesthesiologists contribute to better continuity of care across the perioperative period, ensuring seamless transition from intraoperative management to postoperative critical care. These benefits are particularly evident in specific pediatric populations. Postoperative pediatric surgical patients, especially those undergoing correction of congenital anomalies such as tracheoesophageal fistula and congenital diaphragmatic hernia (including Bochdalek and Morgagni types), frequently require specialized ventilatory and hemodynamic support. Similarly, children with cardiovascular compromise, including those with dilated cardiomyopathy or heart failure, benefit from precise hemodynamic monitoring and targeted therapeutic interventions provided by Anesthesiologists. In addition, pediatric patients with respiratory failure represent a major group in which Anesthesiologist expertise is critical; this includes hypoxemic respiratory failure, commonly seen in conditions such as bronchiolitis and pneumonia, as well as hypercapnic respiratory failure associated with severe asthma. Neuromuscular disorders, including Guillain–Barré syndrome and myasthenia gravis, further highlight the importance of specialized ventilatory management and pharmacologic considerations in the PICU. Conclusion: Anesthesiologists play a key role in the PICU, contributing expertise in airway management, ventilation, hemodynamic support, and sedation tailored to pediatric physiology. Their involvement improves patient safety, perioperative continuity, and clinical outcomes, particularly in high-risk groups such as postoperative patients and those with respiratory or cardiovascular compromise. Strengthening pediatric critical care training within anesthesiology is essential to optimize the PICU care.
