prodromal labor

Etymology: Gk, prodromos, running before; L, labor, work
the early period in parturition before uterine contractions become forceful and frequent enough to result in progressive dilation of the uterine cervix.

pro·dro·mal la·bor

(prō-drō'măl lā'bŏr)
An early phase of labor that does not progress in a normal pattern: contractions do not increase in intensity and cervical dilatation is minimal.
Compare: active labor

prodromal labor

The initial changes that precede actual labor, usually occurring 24 to 48 hr before the onset of labor. Some women report a surge of energy. Findings include lightening, excessive mucoid vaginal discharge, softening and beginning effacement of the ripe cervix, scant bloody show associated with expulsion of the mucus plug, and diarrhea.
