Intrauterine Growth Retardation Related to Maternal Erythrocyte Oxygen Transport
Intrauterine growth retardation (IUGR),. is a term applied to fetuses who, at any week of gestation, are undersized for the duration of pregnancy. IUGR is a common problem contributing to 3.5% to 43% of all births (Lin and Evans, 1984). These infants frequently have asphyxia, meconium aspiration, persistent fetal circulation, polycythemia, hypoglycemia and congenital malformations. The causes of IUGR are diverse and can be attributed to maternal, fetal, placental or other unknown factors. Included in the latter group is a subset with inadequate oxygenation whose etiology remains elusive.
