The first volume in the “What Do I Do Now?: Emergency Medicine” series, Pediatric Medical Emergencies uses a case-based approach to cover common and important topics in the examination, investigation, and management of acutely ill children. Each chapter provides a discussion of the diagnosis, key points to remember, and selected references for further reading. Areas of controversy are clearly delineated with a discussion regarding evidence-based options and a balanced view of treatment and disposition decisions. The book addresses a wide range of topics including neonatal fever, pediatric sepsis, intussusception, and more, and is suited for emergency medicine providers and pediatricians. Pediatric Medical Emergencies is an engaging collection of thought-provoking cases which clinicians can utilize when they encounter difficult pediatric patients. The volume is also a self-assessment tool that tests the reader’s ability to answer the question, “What do I do now?”
