The New Ballard Score allows scores of −1 for the criteria, hence making negative scores possible. The possible scores then range from −10 to 50, the gestational range extending up to 20 weeks. (A simple formula to come directly to the age from the Ballard Score is Age=((2*score)+120)) / 5. Maturity Rating:
For example, if there is a gestational age based on the beginning of the last menstrual period of 9.0 weeks, and a first-trimester obstetric ultrasonography gives an estimated gestational age of 10.0 weeks (with a 2 SD variability of ±8% of the estimate, thereby giving a variability of ±0.8 weeks), the difference of 1.0 weeks between the ...
Gestational age: 35 and 0 days until 39 weeks and 6 days old. Embryonic age: Weeks nr 34–38. 33–37 weeks old. The fetus is considered full-term at the end of the 39th week of gestational age. It may be 48 to 53 cm (19 to 21 in) in length. The lanugo is gone except on the upper arms and shoulders. Fingernails extend beyond fingertips.
Fundal height, when expressed in centimeters, roughly corresponds to gestational age in weeks between 16 and 36 weeks for a vertex fetus. When a tape measure is unavailable, finger widths are used to estimate centimeter (week) distances from a corresponding anatomical landmark.
An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
Naegele's rule is a standard way of calculating the due date for a pregnancy when assuming a gestational age of 280 days at childbirth. The rule estimates the expected date of delivery (EDD) by adding a year, subtracting three months, and adding seven days to the origin of gestational age.
The costs increase exponentially with decreasing gestational age and weight. [207] The 2007 Institute of Medicine report Preterm Birth [ 208 ] found that the 550,000 premature babies born each year in the U.S. run up about $26 billion in annual costs, mostly related to care in neonatal intensive care units, but the real tab may top $50 billion.
The gestational age at diagnosis: Babies with anhydramnios diagnosed in the early stages of pregnancy have a poorer prognosis than babies with anhydramnios diagnosed in the later stages of pregnancy.
