On clinical examination, RR > 60/min for > 2 hours, grunting, flaring of nasal alae, subcostal, intercostals retractions, diffuse reticulogranular
pattern and air bronchogram on X-ray chest, arterial blood gas done whenever necessary was done and all preterms < 37 wks.
The neonates were labelled as RDS if they developed respiratory distress within six hours and chest X-ray showed one or more of the following; poor expansion with air bronchogram, reticulogranular
pattern and ground glass opacity.
appearance was present on lung graphy of the patient who was ventilated mechanically because of respiratory failure and respiratory acidosis.
pattern, or ground glass appearance, uniformly distributed throughout both lung fields.
7] Typical chest X-ray findings of low volume lungs with a diffuse reticulogranular
pattern and air bronchogram supported the diagnosis.
RDS categories were defined as: Category 1) reduced lung volume with a diffuse reticulogranular
pattern, air bronchograms mild or absent; Category 2) reticulogranular
pattern more prominent and uniform, lungs hypoaerated with increased air bronchograms; Category 3) progressive opacification of the anterior portions of the lungs with mild obscuration of cardiac silhouette; and Category 4) (lungs appear opaque and display prominent air bronchograms, with total obscuration of cardiomediastinal silhouette.
7% of 129 patients who were diagnosed with Kawasaki disease, reticulogranular
appearance was observed in 89.
