Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
Most screening for LGA and macrosomia occurs during prenatal check-ups, where both fundal height and ultrasound scans can give an approximate measurement of the baby's proportions. [38] Two-dimensional ultrasound can be used to screen for macrosomia and LGA but estimations are generally not precise at any gestational age until birth. [36]
The condition is defined by birth weight and/or length. [citation needed]Intrauterine growth restriction is generally diagnosed by measuring the mother's uterus, with the fundal height being less than it should be for that stage of the pregnancy.
"She’s been a happy and perfect baby and now looking at both of them as twins, you can’t tell which one had the issue at all. They are both happy 1-year-old girls.” ...
A baby born within the normal range of weight for that gestational age is known as appropriate for gestational age (AGA). An abnormally slow growth rate results in the infant being small for gestational age, while an abnormally large growth rate results in the infant being large for gestational age.
It is rare for a baby weighing less than 500 g (17.6 ounces) to survive. [13] A baby's chances for survival increases 3–4% per day between 23 and 24 weeks of gestation and about 2–3% per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [15]
For this reason, discrepancies between fundal height measurements and gestational age can be a clinical indication of amniotic fluid abnormality and should be evaluated by ultrasound. The symptoms of anhydramnios may not always be apparent, but some potential signs include: A decrease in the size of the baby's abdomen [13] Decreased fetal ...
In 2004, of the people younger than 35 who gave birth with the help of IVF, 32.7% delivered twins, and 4.9% delivered triplets, according to doctors at the Washington University School of Medicine ...
