Newborns with severe congenital pleural effusions often present with respiratory failure at birth. We describe two premature infants born at 31 and 33 weeks of gestation with bilateral pleural effusions. Both were drained prior to delivery under ultrasound guidance. The first infant had severe bilateral congenital chylothorax with pulmonary hypertension; the second infant had severe nonimmune hydrops fetalis. Both could be adequately oxygenated but failed to respond to conventional mechanical ventilation (CMV) and chest tube drainage, so that CO(2) elimination could not be accomplished. Both infants were successfully treated with high-frequency ventilation (HFV). We suggest that HFV may be of significant value in establishing adequate ventilation in cases of severe congenital pleural effusions.
