cervical ripening

The stromal response of the cervix in phase 1 of parturition, which precedes the onset of labour, in which the cervix becomes softer and more dilatable.

Obstetrics The stromal response of the cervix in phase 1 of parturition, which precedes the onset of labor, in which the cervix becomes softer and more dilatable. See Cervical effacement.

cervical ripening

The biochemical changes in the cervix that take place gradually over the last few weeks of gestation in preparation for childbirth. The cervix softens, and its potential for stretching increases. Normally this occurs naturally, but in postterm pregnancies it may be necessary to use mechanical dilators or drugs. Placement of Laminaria digitata or prostaglandin E analogs (e.g., misoprostol) in the vagina or cervical canal promotes cervical ripening and onset of labor but does not reduce the rate of cesarean deliveries.

Patient care

Fetal status is assessed by monitoring the heart rate for 30 min before gel insertion and for approx. 1 hr after the procedure. The woman is assessed for uterine contractions and signs of hyperstimulation, nausea, or vomiting. If hyperstimulation occurs, the gel is removed, and the primary health care provider is notified.

For the misoprostol group, using the hospital protocol, a 50 [micro]g tablet was inserted into the posterior fornix of the vagina, and it was repeated 6 hourly until an adequate contraction pattern (3-5 contractions in ten minutes, each lasting between 40 and 60 seconds), sufficient cervical ripening (Bishop score greater than 7 or cervical dilatation of at least 4 cm), or spontaneous rupture of membranes was achieved, or a maximum of four doses had been given.
