Is Chronic Lung Disease in Low Birth Weight Infants P Preventable? A Survey of Eight Centers t bl ? A S f Ei ht C t Avery ME et al Pediatrics 1987; 79; 26‐30
The Columbia Difference: The Columbia Difference: • Instituted CPAP at 5 cm H2O pressure with nasal prongs after birth in all weight groups for signs and prongs after birth in all weight groups for signs and symptoms of respiratory distress applied in delivery room • Hyperventilation was avoided and PaCO2 value was allowed to go as high as 60 mm Hg before endotracheal intubation • Muscle relaxants were not used. Minimal but adequate ventilator settings with mechanical ventilation il i ih h i l il i • Jen‐ Tien Wung MD supervised ventilatory care full time

Permissive / Therapeutic Hypercapnia Permissive / Therapeutic Hypercapnia • Intentional Intentional hypoventilation to avoid hypoventilation to avoid volutrauma and diminish lung injury either by avoiding ventilation or employing low‐tidal‐ avoiding ventilation or employing low tidal volume ventilation. • Limited controlled data in infants to support Limited controlled data in infants to support its efficacy & safety. • Is there a role for therapeutic hypercapnia?

Permissive Hypercapnia: Adverse Effects Permissive Hypercapnia: Adverse Effects • Increased Increased pulmonary vascular resistance pulmonary vascular resistance (hypoxemia) • Alterations in cerebral blood flow (IVH) Alterations in cerebral blood flow (IVH) • Opening blood‐brain barrier (kernicterus) • Increased intrapulmonary shunt (hypoxemia) • Impaired myocardial contractility p y y
