Induction of labor
Definitions

Initiation of uterine contractions by medical or surgical means for the purpose of delivery before the spontaneous onset of labor (i.e., before labor has begun).

Examples of methods include, but are not limited to: artificial rupture of membranes, balloons, oxytocin, prostaglandin, luminaria , or other cervical ripening agents.

Instructions

Check this item if medication was given or procedures to induce labor were performed before labor began. If it is not clear whether medication or procedures were performed before or after labor had begun, review records to determine when labor began and when medications were given or procedures performed. If this information is unclear or unavailable, check with the birth attendant.

Induction of labor should be checked even if the attempt to initiate labor is not successful or the induction follows a spontaneous rupture of the membrane without contractions.

NOTE: Does not include augmentation of labor, which applies only after labor or contractions have begun.

Steroids (glucocorticoids) for fetal lung maturation received by the mother before delivery.

Steroids include: betamethasone, dexamethasone, or hydrocortisone specifically given to accelerate fetal lung maturation.

Does not include steroid medication given to the mother for anti-inflammatory treatment before or after delivery.
