Management and complications of pneumonia

Pneumonia is estimated to be the leading cause of mortality in children under five worldwide. Death is rare in developed countries but it remains a major cause of hospital admissions and of both acute and chronic morbidities. Understanding current management and recognition of complications is important to all paediatricians. The causative organism varies with age and differentiating between viral, bacterial and other causes can be challenging. Supportive care and antibiotic treatment are the mainstays of modern management. The evidence base to support treatment policy is remarkably weak.The incidence of both uncomplicated and complicated pneumonia is increasing, particularly that of empyema and necrotic lung disease. The management of complications has changed over recent years and remains the subject of some controversy. The syndrome of inappropriate anti-diuretic hormone secretion (SIADH) has long been cited as a complication of pneumonia; but the existence of this entity is now being questioned. There is increasing evidence that pneumonia increases the risk of chronic obstructive pulmonary disease, bronchiectasis and asthma in later life.
