This edition of the book in the specialty series of the Academy on Pediatric Intensive Care is designed to bring an overview of the most important aspects of critical care and its practice to the readers. It does not attempt to be a complete textbook on the subject. Each chapter is written for clarity and conciseness. Clear concepts of pathophysiology and management are laid out for the comfort of even a first-time reader. For the students, the book can be a handy mix of manual and textbook and a good introduction to the subject before venturing onto a weightier tome. For the practitioners, there are management practices that are easy to follow and remember. Many chapters have been written by authorities in that area and all by intensivists experienced in teaching and practice, bringing an ideal blend of theory and practice for easy applicability. This is a must-have book for every aspiring intensivist and for all who will take care of critically ill children.
