title: Neonatal polycythemia in low birthweight infant.
abstract: 74 low birthweight infants haematologic findings were studied during the first 24 hours and at the 8th day of life. By statistical methods derived from the multivariate analysis: stepwise multiple regression analysis and factor analysis, correlations were investigated between haemogram data (red cells count, haemoglobin and haematocrit levels and 18 others parameters. Most of the infants with polycythemia have toxaemic mothers and were born after a long gestation: they are affected by intra-uterine growth retardation, have a low glycaemia level but a normal calcaemia level, a large skull perimeter and a small thymus volume. But no correlation was observed between polycythemia and the following data: heart volume, neonatal icterus intensity, reticulocytes and erythroblasts counts.
