This book is a comprehensive, case-based exploration of the major and most common life-threatening conditions faced by pediatric intensivists in daily clinical work. The selected topics reflect conditions that demand complex physiologic reasoning, multidisciplinary decision-making, and timely escalation of care. The chapters are built mostly around fictionalized clinical cases that were developed on the basis of authentic patient encounters and, in many instances, integrate elements from more than one real case into a single narrative in order to represent clinical complexity. Complications and management challenges were intentionally embedded throughout the chapters, allowing the book as a whole to address a wide range of diagnostic dilemmas, therapeutic decisions, and adverse events that pediatric intensivists must be prepared to manage. Topics that are introduced briefly in one chapter may be expanded upon in greater depth in others, reflecting a deliberate pedagogical approach that emphasizes cumulative learning, cross-referencing, and conceptual integration across disease categories.

The book is organized into thematically linked sections encompassing major domains of pediatric intensive care, including congenital and acquired cardiac disease, neurocritical care, respiratory failure, shock, trauma, complex infectious syndromes, metabolic and toxicologic emergencies, renal failure, and advanced airway management. Clinical trajectories typically follow patients from initial presentation through intensive care management, the development of complications, advanced organ support, and longer-term outcomes. Each chapter integrates pathophysiologic explanation with evidence-informed diagnostic and therapeutic reasoning, allowing readers to follow the dynamic evolution of critical illness in a clinically authentic manner. Figures and dedicated boxes are used to reinforce key concepts and to highlight essential mechanisms, common pitfalls, and areas of ongoing uncertainty.

This book is intended for pediatric intensivists, fellows in pediatric critical care and related subspecialties, emergency physicians, anesthesiologists, surgeons, and advanced practice providers involved in the care of critically ill children. It is designed not as a protocol manual, but as a case-driven educational and clinical companion that mirrors real-world reasoning, evolving physiology, and the complexity of decision-making in the pediatric intensive care unit. Through its structured yet flexible approach, the book aims to support both advanced training and reflective clinical practice in pediatric critical care.

Dr. Ori Attias is a consultant in Pediatric Critical Care Medicine at the Ruth Rappaport Children’s Hospital, Rambam Health Care Campus, Haifa, Israel, with more than 20 years of clinical experience in the care of critically ill infants and children. Rambam Health Care Campus is one of Israel’s largest tertiary academic medical centers and serves as the major referral center for northern Israel. Its Pediatric Intensive Care Unit is a 15-bed multidisciplinary unit that provides advanced care for more than 1,000 critically ill children with complex medical and surgical conditions each year, including patients requiring extracorporeal membrane oxygenation (ECMO) and transplantation.

Dr. Attias received his medical degree from the Hebrew University of Jerusalem and completed his residency in pediatrics and fellowship in pediatric intensive care at Rambam, followed by an advanced clinical fellowship at Great Ormond Street Hospital in London, United Kingdom. Rambam Health Care Campus is affiliated with the Bruce Rappaport Faculty of Medicine, Technion – Israel Institute of Technology, where Dr. Attias participates in the teaching and mentoring of medical students as part of his clinical practice.

Dr. Attias’s academic work includes peer-reviewed publications in pediatric critical care, nephrology, oncology, and metabolic disease. He has also authored and co-authored chapters in Springer publications, including Abdominal Compartment Syndrome in Pediatric Critical Care Medicine and Easing of Physical Distress in Pediatric Cancer in Palliative Care in Pediatric Oncology. His work focuses on pediatric critical care, evidence-based medicine, and the application of clinical guidelines to complex real-world scenarios.
