Other Comments

The dose is administered in 4 portions of 1 mL/kg each over 2 to 3 seconds each through a 5-French end hole catheter inserted into the endotracheal tube. After each quarter-dose, the catheter should be removed and the infant ventilated for at least 30 seconds or until stable. The infant is then repositioned for the next quarter-dose. The infant should not be suctioned for 1 hour after dosing unless there are signs of significant airway obstruction.

Additional doses of 4 mL/kg may be given at least 6 hours apart if there is evidence of continuing respiratory distress (the infant is still intubated and requires at least 30% inspired oxygen to maintain a PaO2 <=80 torr, or RDS has been confirmed radiographically in infants who had received a prevention dose). Ventilator settings may require adjustment for repeat doses. Manual bag ventilation should not be used to administer repeat doses.

Heart rate, transcutaneous O2 saturation, and ABGs should be closely monitored.
