The 3.2 kg patient with persistent pulmonary hypertension of the newborn (PPHN) has the following order: Infuse norepinephrine 0.05 mcg/kg/min IV and titrate q15 minutes by 0.05 mcg/kg/min to maintain mean arterial pressure between 45 and 55 mm Hg. Overnight, the norepinephrine had been titrated to 0.25 mcg/kg/min for persistent hypotension. At 0900, the MAP rose to 62 mm Hg and the nurse decreased the infusion from 0.25 mcg/kg/min to 0.20 mcg/kg/min. At 0905, the patient’s blood pressure fell to 42 mm Hg.
