Induction of labour is offered when your doctor and midwife think it is better for your baby to be born soon rather than continuing with your pregnancy.
The greatest disadvantage of induction of labour is that it can take longer than spontaneous delivery. Even though side effects can occur during induction of labour most women do not experience complications.
Misoprostol
Misoprostol was originally developed to treat other conditions not related to pregnancy and labour, but as it also stimulates uterine contractions Misoprostol tablets have been used to induce labour in Denmark and other countries for many years.
There is a very small risk that prostaglandins may course your uterus to be overstimulated. This means that you may develope very intense, frequent, or long-lasting contractions, which could be stressfull for your baby. If your womb does start to hyperstimulate, you can be given medication to stop or slow down your contractions, so it is important that you contact the Labour Ward when you feel the contractions starting.
There is an extremely small risk that your uterus will react so strongly towards the prostaglandin that the uterus may rupture. If this happens then an emergency Caesarean section must be performed.
Artificial rupture of membranes
Before rupturing the membranes a vaginal examination will be performed to ensure that the procedure can be performed safely. There is a small risk that the umbilical cord can be compressed after the membranes have been ruptured or that the baby's head will be descend with a little more difficulty, which may prolong labour.
Balloon Catheter
The use of a balloon catheter may increase the risk of infection in the uterus. There is also a small risk that the baby's head will descend with a little more difficulty.
The balloon catheter can often give period-like cramps which can be relieved by removing some of the water from the balloons.
Intravenous infusion of oxytocin
There is a risk for overstimulation of the uterus where contractions are too frequent or are prolonged, so the contractions and the baby's heart rate will be monitored continuously by CTG.
There is an extremely small risk that very powerful uterine contractions can cause the uterus to rupture. If this happens, an emergency Caesarean section will be performed.
