Bronchiolitis typically affects infants and children younger than two years, principally during the autumn and winter. [15] It is the leading cause of hospital admission for respiratory disease among infants in the United States and accounts for one out of every 13 primary care visits. [ 8 ]
Prolonged high oxygen delivery in premature infants causes necrotizing bronchiolitis and alveolar septal injury, with inflammation and scarring. This results in hypoxemia . Today, with the advent of surfactant therapy and high frequency ventilation and oxygen supplementation, infants with BPD experience much milder injury without necrotizing ...
Typically found in young children and is the most common cause at this age. [31] Generally occurs after a viral infection of adenovirus (types 3, 7, and 21), measles (rubeola), mycoplasma, CMV, influenza, and parainfluenza. [4] [6] Swyer-James syndrome is a rare complication of bronchiolitis obliterans caused by measles or adenovirus. [32]
Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles (bronchiolitis) and surrounding tissue in the lungs. [2] [3] It is a form of idiopathic interstitial pneumonia. [4]
For children younger than 15 years old, nasopharyngel catheters or nasal prongs are recommended over a face mask or head box. [26] A Cochrane review in 2014 presented a summary to identify children complaining of severe LRTI, however; further research is required to determine the effectiveness of supplemental oxygen and the best delivery method.
Complications from BPD can follow a patient into adulthood. As a child they may experience learning disabilities, pulmonary hypertension, and hearing problems. As an adult, there is an increased likelihood for asthma and exercise intolerance. [20] Meconium Aspiration Syndrome occurs in full term or post-term infants who aspirate meconium.
[3] [13] About 5% of adults are affected and about 6% of children have at least one episode a year. [7] [8] It occurs more often in the winter. [7] In infants under one year of age, acute bronchitis was the most common reason for admission to the hospital after an emergency department visit in the US in 2011. [31]
