Key takeaways
- All neonatal vasoactive and inotropic infusions must run via continuous infusion pumps, and the maximum concentrations strictly require central venous access.
- Dobutamine is diluted to a recommended neonatal concentration of 1 mg/mL (absolute maximum 2 mg/mL with central access) and dosed 2–25 mcg/kg/min.
- Dobutamine requires continuous cardiac and blood-pressure monitoring and carries a high extravasation/phlebitis risk.

Universal Neonatal Infusion Parameters
Universal Neonatal Infusion Parameters
- Mandatory Equipment: All continuous infusions must be administered strictly via continuous infusion pumps (BIC) to ensure precise, titrated dosing.
- Line Access Limits: Lower concentrations may be administered peripherally. Higher maximum concentrations strictly require central venous access to prevent tissue damage.
- Fluid Capacity Restrictions: Neonatal dilutions are highly variable. Final volumes must be meticulously calculated based on the strict fluid volume limits (capacidade hídrica) of the individual patient.

Dobutamine | Administration & Monitoring
DOBUTAMINE | Administration & Monitoring
- Cardiac Monitoring: Continuously monitor HR and rhythm. Watch closely for pathological elevation in HR or ventricular ectopic activity.
- Hemodynamic Monitoring: Strict continuous monitoring of Blood Pressure (PA) required during titration.
- Renal Output: Track strict urine output to assess organ perfusion efficacy.
- Extravasation Risk: High risk of phlebitis and severe tissue necrosis. Avoid extravasation at all costs. Utilize large-caliber veins or central access only.
Chemical & Visual Alerts
- Alkaline Incompatibility: Do NOT infuse Dobutamine with sodium bicarbonate or other strongly alkaline solutions.
- Oxidation Note: Solutions may develop a pink discoloration due to oxidation. This is harmless and causes no significant loss of potency within 24 hours.

MILRINONE | Neonatal Infusion Timing
MILRINONE | Neonatal Infusion Timing
- Term Neonates & Children: 15 to 60 Minutes
- Premature Neonates (< 30 Weeks): 3 Hours
Critical Pharmacokinetics: Premature clearance of the drug is significantly slower. Rapid administration severely increases the risk of life-threatening hypotension.
Note: Maintenance continuous infusion follows this specific loading dose via pump, meticulously titrated to clinical effect.
MILRINONE | Critical Interactions & Safety
MILRINONE — FUROSEMIDE
DO NOT MIX (Precipitation Risk)
Hemodynamic Alert Box
Hypotension Risk
Continuous blood pressure (BP) monitoring is mandatory.
Furosemide instantly precipitates Milrinone. If systemic hypotension occurs, immediate reduction of flow or total interruption of infusion is required.
