Amniotic fluid cortisol concentrations in normal labor, premature labor, and postmature pregnancy. 1977

U C Nwosu, and R J Bolognese, and E E Wallach, and A M Bongiovanni

Amniotic fluid cortisol concentration was measured in 61 gravidas during the third trimester prior to onset of labor. These patients had had normal prenatal courses and served as controls. Cortisol values obtained were compared with those of 1) gravidas with prolonged pregnancy (greater than 42 weeks) who delivered post-mature neonates (N=6), 2) gravidas in spontaneous term labor (N = 10), and 3) gravidas in premature labor (N=10). The mean level of amniotic fluid cortisol (+/-SD) found in those women with premature labor was significantly elevated compared to control values (P less than 0.05). Levels recorded in premature labor patients were in the same range as in the term spontaneous labor group (3.7+/-2.5 vs. 2.7+/-1.5; P greater than 0.3). No difference was found between the spontaneous labor group or the postmature group and their respective controls.

UI	MeSH Term	Description	Entries
D007743	Labor, Obstetric	The repetitive uterine contraction during childbirth which is associated with the progressive dilation of the uterine cervix (CERVIX UTERI). Successful labor results in the expulsion of the FETUS and PLACENTA. Obstetric labor can be spontaneous or induced (LABOR, INDUCED).	Obstetric Labor
D007752	Obstetric Labor, Premature	Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).

D011273	Pregnancy, Prolonged	A term used to describe pregnancies that exceed the upper limit of a normal gestational period.
