title: Failure of serial chest radiographs to predict recovery from respiratory distress syndrome.
abstract: Chest radiographs of 29 patients with the clinical and radiographic diagnosis of RDS during the 5 days of the illness were graded according to a modification of the classification of Bomsel. There was no significant difference between the radiographs of surviving neonates and those who died of RDS. Mean L/S ratios were also collected from 26 of the 29 patients. Those who survived had significantly more mean L/S ratios greater than 2.5 than did the nonsurvivors (p less than 0.01). This difference did not correlate with the staging of the chest radiographs. The mean L/S ratio is a better predictor of survival than chest radiographs during the first 5 days of RDS.
