Maintenance infusion: 0.375 to 0.75 mcg/kg/min.
Usual Pediatric Dose for Congestive Heart Failure
less than 1 month:
Hemodynamic support: Full term neonates: Loading dose: 50 to 75 mcg/kg IV administered over 15 minutes followed by a continuous infusion of 0.5 mcg/kg/minute; titrate to effect; range: 0.25 to 0.75 mcg/kg/minute has been used by several centers. One report used a loading dose of 50 mcg/kg IV administered over 15 minutes, followed by a continuous infusion of 0.5 mcg/kg/minute for 30 minutes in 10 neonates (3 to 27 days old, median age: 5 days) with low cardiac output after cardiac surgery; results showed improved hemodynamic parameters and milrinone was well tolerated.
Prevention of postoperative low cardiac output syndrome (CHD corrective surgery): Full term neonates: Loading dose: 75 mcg/kg IV administered over 60 minutes followed by a continuous IV infusion of 0.75 mcg/kg/minute for 35 hours was used in a randomized, placebo controlled trial of 227 patients (age: 2 days to 6.9 years, median: 3 months) and showed 64% relative risk reduction for development of low cardiac output syndrome compared to placebo; a lower milrinone dose used in the study did not show a statistically significant relative risk reduction compared to placebo for the same endpoint.
1 month and older:
Loading dose: 50 mcg/kg IV over 15 minutes.
Maintenance infusion: 0.25-1 mcg/kg/min.
