Screening echocardiograms for: |
Severe BPD at 36 weeks |
Infants with prolonged ventilator and/or oxygen requirements |
Cyanotic episodes |
Marked hypercarbia |
Persistent pulmonary edema, diuretic dependence |
Poor growth, IUGR, oligohydramnios |
General evaluation and treatment for factors contributing to persistent respiratory disease and PH |
Ensure adequate oxygenation (awake, asleep, feeds) |
Assess the adequacy of ventilation |
Chronic aspiration (barium swallow, swallowing study, pH probe, impedance study) |
Structural airway disease: malacia, subglottic stenosis |
Optimal treatment of reactive airways disease |
Neurological abnormalities: hydrocephalus |
Ensure optimal nutrition |
Consider cardiac catheterization when work-up fails to reveal a clear etiology for poor clinical status or when optimal management of these factors fail to achieve clinical improvement |
Assess severity of PH |
Anatomic heart disease/shunt lesions |
Structural vascular abnormalities (eg, arterial stenosis, pulmonary venous obstruction, systemic to pulmonary collateral vessels, others) |
Catheter-based interventions |
Assess cardiac function (LV diastolic dysfunction) |
Acute vasoreactivity/hypoxia testing for selection of chronic therapy |
BPD: bronchopulmonary dysplasia, IUGR: intrautuerine growth restrcition, PH: pulmonary hypertension, LV left ventricular
