excellence in clinical care delivery models. It can be rightly said that pediatric critical care medicine belongs to the global village of practitioners and scientists who strive tirelessly to improve the health and future of critically ill children across the world.Advances in pediatric critical care medicine encompass a better understanding of disease states, newer interventions with innovations in therapeutics and devices, and better team integration of multiple disciplines and workflow processes to enhance the quality of care and outcomes from critical illness in children. From the early days of physician-driven care of infants with acute respiratory failure requiring manual hand ventilation to the modern interdisciplinary ICU with complex decision support and advanced ventilator technologies involving smart devices and skilled teams of physicians, nurses, respiratory therapists, and pharmacists, the clinical care of critically ill children has been greatly enhanced through advances in scientific research and quality improvement methods. This special series on pediatric critical care medicine is a curated collection of cutting-edge articles by leading clinician-scientists from across the world in the field of pediatric critical care medicine. As editors, we are particularly proud to have assembled this series of articles authored by a diverse group of multidisciplinary experts from different geographical regions. These articles emphasize how scientific evidence can build the foundation for outstanding clinical care to improve outcomes in pediatric critical illness. Some articles cover well-known disease states such as acute respiratory distress syndrome (4,5), severe sepsis (6,7) and septic shock (8), and traumatic brain injury (9) and provide the latest translational science context that serves to underpin our current understanding of how best to care for these children (10)(11)(12). Other articles emphasize the evidence for best practices for ICU interventions such as sedation management (13), nutrition therapy (14,15), and early mobilization with rehabilitation (16). These articles also focus on topical and relevant issues such as pandemic considerations for the ICU (17), the role of the microbiota (14), and moral and ethical dilemmas in the care of critically ill children (18-21). Together, these articles serve as a compendium of how best to translate scientific evidence into the art of caring for critically ill children across the globe.
