OBJECTIVE: Characterize the diagnosis of PDA and the distribution of pretreatment platelet count in pharmacologically managed PDA in infants ≤1500 g and assess the relationship of platelet count to serious morbidities.
STUDY DESIGN: This is a retrospective, observational study. In 40 hospitals, data were collected on PDA, including pretreatment platelet count. Distribution of platelet count was examined. The association of platelet count and clinical outcomes of IVH, NEC and PDA closure prior to discharge were examined. Chi-square test was used to compare outcomes by platelet count groups.
RESULTS: There were 311 patients treated with medically treated PDA. Pretreatment platelet counts were categorized as 0-119 K, 120-199 K, 200-299 K, >300 K. Incidence and grade of IVH were not significantly different by platelet group. Across all groups: No IVH 62-83%, Grades 1-2 IVH 13-25%, Grades 3-4 IVH 2-13%. NEC occurred in 0-11% of all patients studied. PDA closure rate was 33-45%.
CONCLUSION: PDA closure was not significantly affected by platelet count. Platelet count was not a statistically significant factor for development of IVH and NEC in infants born <1500 g with pharmacologically treated PDA.
