Background: As neonatal central diabetes insipidus is rare in preterm neonates with intraventricular hemorrhage (IVH), very little is known about dosing and the route of administration of desmopressin treatment.Case report: We present a preterm neonate born at 29 weeks' gestation. Within 24 h, she developed bilateral IVH with subsequent post-hemorrhagic hydrocephalus. On the 3rd postnatal day, she developed diabetes insipidus for which she was intranasally administered 0.2 mg desmopressin. This resulted in oliguria with several hours of anuria and a 25-point drop in sodium levels within 15 h. Conclusion: The determination of the desmopressin dose in a preterm neonate is a challenge and there is no consistent literature about the dosing or the route of administration. We suggest starting with a low dose of intranasal desmopressin (0.05-0.1 μg) and titrate in accordance with clinical and laboratory parameters.
