This book is designed to fit into a handbag or shirt pocket. It contains material which is usually required in a hurry when treating a critically ill or injured infant or child. In addition to information relevant to emergency care, there are what we hope will be useful pages of data on subjects which without a photographic memory would normally require reference to a paediatric text book. Examples include a weight for height chart, normal values for common biochemical tests, normal developmental profiles and normal ECG measurements
