Induction of Labour
Description
1. The deliberate initiation of labour before spontaneous
contractions begin may be either mechanical (amniotomy
[i.e., rupture of amniotic membranes]), physiologic
(ambulation and nipple stimulation), or chemical
(prostaglandins and oxytocin).
2. Artificial rupture of membranes (AROM) may be adequate
stimulation to initiate contractions, or AROM may be done
after oxytocin administration establishes effective
contractions.
3. Induction and AROM are initiated when the cervix is soft,
partially effaced, and slightly dilated, preferably when the
fetal presenting part is engaged.
4. Oxytocin-induced labour must be done with careful,
ongoing monitoring; oxytocin is a powerful drug.
