Does surfactant therapy failure identify infants at risk for pulmonary mortality?
Pulmonary processes unresponsive to surfactant therapy contribute to morbidity and mortality in newborn respiratory distress syndrome. Classifying respiratory distress syndrome as "surfactant responsive" or "surfactant unresponsive" offers a scheme by which to investigate alternative explanations and interventions for newborn respiratory distress syndrome.
Newly developed giant negative T waves with QT prolongation in the ECG may indicate myocardial stunning, but do not in themselves imply a poor prognosis. The marked preponderance of middle-aged and elderly women with this type of myocardial ischemia remains to be explained.
