Usual Pediatric Dose for Respiratory Distress Syndrome

Less than 48 hours of life:

• Prevention of RDS in infants less than 1250 g birth weight: 100 mg/kg birth weight intratracheally, preferably within 15 minutes of birth
• Treatment (rescue) of RDS: 100 mg/kg birth weight intratracheally, preferably by 8 hours of age

• Maximum dose: Total of 4 doses within 48 hours of life

Comments:

• This drug significantly reduces the incidence of mortality due to RDS and air leak complications.
• Marked improvements in oxygenation may occur within minutes of administration; monitor frequently and carefully the systemic oxygenation to avoid hyperoxia.
• Stop the dosing procedure if the infant experiences bradycardia or oxygen desaturation; initiate appropriate measures to alleviate the condition, and resume treatment after the infant has stabilized.
• Rales and moist breath sounds can occur transiently after administration.
• If clear-cut signs of airway obstruction are present, endotracheal suctioning or other remedial action may be necessary.

Uses:
