Chadwick’s Sign – A deep blue-violet color of the cervix and vagina caused by increased vascularity. It is a probable sign of pregnancy that becomes evident around the fourth week of gestation. Effacement – In obstetrics, the thinning of the cervix as the internal os is slowly pulled up into the lower uterine segment. Engagement – In obstetrics the entry of the largest diameter of the fetal presenting part into the pelvic inlet. Erythema toxicum – A benign, self-limited erythema marked by firm, yellow-white papules or pustules from 1 to 2 mm in size present in about 50% of full-term infants. The cause is unknown, and the lesions disappear without need for treatment. Episiotomy – Incision of the perineum at the end of the second stage of labor to avoid spontaneous laceration of the perineum and to facilitate delivery. In the U.S. episiotomy is done in about 40% of all vaginal deliveries, making the procedure one of the most common forms of surgery performed on women. Perineal massage in the weeks before delivery can reduce the use of episiotomy. Gravida – A pregnant woman.
Goodell’s Sign – indication of pregnancy. It is a significant softening of the vaginal portion of the cervix from increased vascularization. This vascularization is a result of hypertrophy and engorgement of the vessels below the growing uterus. This sign occurs at approximately four weeks' gestation. Hegar’s Sign – a non-sensitive indication of pregnancy in women — its absence does not exclude pregnancy. It pertains to the features of the cervix and the uterine isthmus. It is demonstrated as a softening in the consistency of the uterus, and the uterus and cervix seem to be two separate regions.
