Презентация на тему Intrauterine growth retardation small for gestational age and premature newborns

(SGA), although related, are not synonymous. IUGR is a

deviation from, or a reduction in, an expected fetal growth pattern and is caused by innate reduced growth potential or by multiple adverse effects on the fetus.
IUGR is the result of any process that inhibits the normal growth potential of the fetus. Fetal growth at term may be predicted by anthropometric analysis of fetal dimensions with second-trimester ultrasonography.

is directly related to the low-birthweight rate in a given population.
These high-risk infants are a heterogeneous group consisting of infants born preterm (less than 37 weeks) and those born at term but of reduced weight

g) is not always premature (earlier than 37 weeks).

Worldwide, more than 20 million infants are born weighing less than 2500 g. Between 30% and 40% of these infants are born at term gestation and are therefore undergrown (SGA status).
