The second edition of this pocket book is for use by doctors, senior nurses and other senior health workers who are responsible for the care of young children at the first referral level in developing countries. It presents up-to-date clinical guidelines which are based on a review of the available published evidence by subject experts, for both inpatient and outpatient care in small hospitals where basic laboratory facilities and essential drugs and inexpensive medicines are available. In some settings, these guidelines can be used in the larger health centers where a small number of sick children can be admitted for inpatient care. The guidelines are for use in both inpatient and outpatient care in hospitals with basic laboratory facilities and essential medicines. These guidelines focus on the management of the major causes of childhood mortality in most developing countries, such as newborn problems, pneumonia, diarrhoea, malaria, meningitis, septicaemia, measles and related conditions, severe acute malnutrition and paediatric HIV/AIDS. It also covers common procedures, patient monitoring and supportive care on the wards and some common surgical conditions that can be managed in small hospitals.
