[Neonatal hyperbilirubinemia: evaluation and treatment]

We have analyzed 132 newborns with hyperbilirubinemia (BW < 2500 g, GW > 37 weeks) hospitalized in Neonatal Unit of Paediatric Hospital during 2001. In 78 out of 132 (59.1%) newborns, causal diagnosis were established. Rh isoimmunization caused hyperbilirubinaemia in 2.8% (3/132) cases, ABO isoimmunization in 15.95% (21/32), infections in 9.15% (12/32) and other (polycitaemia, kephalhaematoma, loss of weight > 8%, jaundice related to the brestafeeding) in 31.8% (42/132). Maximal serum bilirubin level was reached between fourth and seventh day of life. In 47/132 newborns (40.9%) non-specific hyperbilirubinaemia were diagnosed. All babies were successfully treated by fototherapy. Blood exchange transfusion was performed in only 2 cases. Rh isoimmunisation was not significant factor in etiology of hyperbilirubinemia because of global prevention of Rh negative mothers. Hyperbilirubinemia of "healthy full-term newborn" was most often seen in 40.9% cases. Diagnostic criteria for hyperbilirubinemia were revised, and fottherapy, as safe, non-invasive method, replaced blood exchange transfusion, as an expansive procedure with low but constant mortality.
