Induction of Labour
There are 3 methods of induction used at Wirral Women and Children’s Hospital, depending on clinical examination and cervical assessment.
Outpatient induction is offered for some women who fit a specific criteria
Prostaglandin Vaginal Pessaries/Tampons
Prostaglandin pessaries are the induction method of choice and are carried out as an inpatient. Individual condition determines which is more suitable.
- Prostin tampon is inserted and left for up to 24 hours or until labour begins or
- Pessary is placed behind the cervix, at the top of the vagina where it dissolves
- Hormones in the pessary cause the cervix to soften and the uterus to contract
Artificial Rupture of Membranes and Syntocinon
If the cervix is assessed and favorable an artificial rupture of membranes (ARM) can be performed. This should be no more uncomfortable than any other vaginal examination.
- Small, slim instrument is used to nick the bag of membranes, releasing some of the water.
- Often this is sufficient stimulation for the uterus to start contracting and labour begins
- An intravenous infusion of a hormone called syntocinon can be used to stimulate the uterus to begin contracting.
