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.
The size of the uterus is assessed at the initial visit, and the growth of the uterus is assessed at subsequent visits. In the first trimester the uterine size can be assessed on bimanual examination. Subsequently, beyond the 12th week of gestation, the uterus can be felt above the pubic bone, and abdominal examinations assess growth. [24]
[1] [5] A 2003 study by the group of Pendergrass et al. also using castings as a measurement method, measured vaginal surface areas ranging from 66 to 107 cm 2 (10.2 to 16.6 sq in) with a mean of 87 cm 2 (13.5 sq in) and a standard deviation of 7.8 cm 2 (1.21 sq in) [6]
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry ...
In 2019, a woman living in Bangladesh with a double uterus gave birth to three babies — first, a baby from one uterus, and then, 26 days later, twins from her second uterus.
In obstetrics, Leopold maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus. They are named after the gynecologist Christian Gerhard Leopold. They are also used to estimate term fetal weight. [1] The maneuvers consist of four distinct actions, each helping to determine the position of the fetus.
How to find your bra size with measuring tape Step 1: Find your bra band size. Wearing an unlined, non-padded bra (not over your clothes!) or a fitted t-shirt, run the measuring tape all the way ...
The most accurate measurement for dating is the crown-rump length of the fetus, which can be done between 7 and 13 weeks of gestation. After 13 weeks of gestation, the fetal age may be estimated using the biparietal diameter (the transverse diameter of the head, across the two parietal bones ), the head circumference, the length of the femur ...
