Official Title
New Therapeutic Approaches to the Resistant Patent Ductus Arteriosus (PDA) in Low Birth Weight Neonates
Brief Summary
Persistent postnatal ductal patency may have significant adverse hemodynamic effects, frequently necessitating therapeutic intervention in order to facilitate ductal closure. Medical therapy for patency of the ductus arteriosus is successful mediating ductal closure in approximately 70% of treated infants. In a recent study in our population, 17% of the babies showed no ductal response to the first course of treatment and 9.4% of our study infants eventually underwent surgical ligation of the ductus after failure of medical therapeutic closure.We propose to evaluate and compare two alternate therapeutic approaches to ductal closure in babies who do not respond to initial therapy.
Study Phase
Phase 2
Study Type
Interventional
Primary Outcome
Our primary objective in this study is to improve ductal closure rates in those infants who do not respond to a first course of therapy.
Secondary Outcome
Our secondary objective is to compare the therapeutic efficacy of two very different secondary treatment protocols.
Condition

Eligibility Criteria
Inclusion Criteria: - Inborn premature neonates admitted to the neonatal intensive care unit of the Shaare Zedek Medical Center and diagnosed as having a hemodynamically significant patent ductus arteriosus (sPDA) will be considered as potential candidates for study if/when they do not respond to initial therapy Exclusion Criteria: - Any baby not considered viable - Any baby with IVH grade 3-4 of recent onset (within 3 days. [If no head ultrasound has been performed within the last 3-4 days, one should performed prior to onset of study.] - Any baby with dysmorphic features or congenital abnormalities - Any baby with structural heart disease other than PDA - Any baby with documented infection, - Any baby with thrombocytopenia (<50,000).
