Hypophosphatemia and Bronchiolitis

Hypophosphatemia In Infants With Severe Bronchiolitis: Prevalence And Risk Factors

Bronchiolitis is a major public health problem and the leading cause of paediatric intensive care unit admission in infants. Hypophosphatemia is common in adult intensive care units and was associated with an increase of the duration of mechanical ventilation and the length of stay. Our hypothesis is that hypophosphatemia is common in bronchiolitis and could be a marker of severity.
