Effacement translates to how 'thin' the cervix is. The cervix is normally approximately three centimetres long, as it prepares for labour and labour continues the cervix will efface until it is 'fully effaced' (paper-thin). Cervical dilation: Closed 1–2 cm 3–4 cm 5+cm Dilation is a measure of how open the cervical os is.
Cervical effacement or cervical ripening refers to the thinning and shortening of the cervix. This process occurs during labor to prepare the cervix for dilation to allow the fetus to pass through the vagina. While this is a normal, physiological process that occurs at the later end of pregnancy, it can also be induced through medications and ...
The cervix changes position in response to the same hormones that cause cervical mucus to be produced and to dry up. When a woman is in an infertile phase of her cycle, the cervix will be low in the vaginal canal; it will feel firm to the touch (like the tip of a person's nose); and the os—the opening in the cervix—will be relatively small ...
Presentation of twins in Der Rosengarten ("The Rose Garden"), a German standard medical text for midwives published in 1513. In obstetrics, the presentation of a fetus about to be born specifies which anatomical part of the fetus is leading, that is, is closest to the pelvic inlet of the birth canal.
Rankins says cervical insufficiency happens when there's painless dilation, or opening, of the cervix, typically in the second trimester of pregnancy, or during weeks 13 through 28.
Partograph. A partogram or partograph is a composite graphical record of key data (maternal and fetal) during labour entered against time on a single sheet of paper. Relevant measurements might include statistics such as cervical dilation, fetal heart rate, duration of labour and vital signs.
Ladin's sign is a clinical sign of pregnancy in which there is softening in the midline of the uterus anteriorly at the junction of the uterus and cervix. It occurs and is detectable with a manual examination at about 6 weeks' gestation. [1] Ladin's sign is often present during the woman's first pelvic exam when pregnancy is suspected. [2]
True cervical pregnancies tend to abort; if, however, the pregnancy is located higher in the canal and the placenta finds support in the uterine cavity, it can go past the first trimester. With the placenta being implanted abnormally, extensive vaginal bleeding can be expected at time of delivery and placental removal.
