The pediatric anesthesiology faculty at Columbia University Medical Center has put together this book as a guide to the practice of clinical anesthesia in neonates, infants, children, and adolescents. The authors are clinicians with considerable experience in the practice of pediatric anesthesiology. They are also teachers of pediatric anesthesiology. Their daily work includes the education and training of residents and fellows in pediatric anesthesiology in a major academic teaching hospital. This book is not “Pediatric Anesthesia for Dummies.” Rather, the authors have organized it as a collection of common and important conditions in children. For each condition, the authors outline the pathophysiology, key perioperative considerations, and important management issues. We hope that residents and practicing physicians will find the book useful as they plan to provide anesthesia care for children.
