Naturally the figures are going to be different when you're looking at two different 'studies' and you also have to take into account the type of hospital the women are having inductions in and the reasons. Some tertiary hospitals take on many 'high risk' cases which would include inductions for medical reasons etc so it will probably be something that you would never get a truly reflective figure on. It's also slightly higher for first time mums who get induced to have a c/s in the end too.

You will hear of many inductions that go perfectly fine, but the stats make it something to be wary of and you do need to be prepared that once you succumb to it, then there could be further intervention etc.

GothMum, FYI, syncto induction can cause PPH as a side effect of the drug. I had a PPH requiring a transfusion after my one and only induction. This is an updated 'adverse reaction' list on the synctocinon from the main site JIC you haven't seen it;

This is taken from the packaging of Syntocinon which has been recently updated:
?ADVERSE REACTIONS
The following adverse reactions have been reported in the mother: Anaphylactic reaction, Postpartum hemorrhage, Cardiac arrhythmia, Fatal afibrinogenemia, Nausea, Vomiting, Premature ventricular contractions, and Pelvic hematoma.
Excessive dosage or hypersensitivity to the drug may result in uterine hypertonicity, spasm, tetanic contraction, or rupture of the uterus.
The possibility of increased blood loss and afibrinogenemia should be kept in mind when administering the drug.
Severe water intoxication with convulsions and coma has occurred, associated with a slow oxytocin infusion over a 24-hour period. Maternal death due to oxytocin-induced water intoxication has been reported.
The following adverse reactions have been reported in the fetus or infant:
Due to induced uterine motility: Bradycardia, Premature ventricular contractions and other arrhythmias, Permanent CNS or brain damage, and Fetal death.
Due to use of oxytocin in the mother: Low Apgar scores at 5 minutes. Neonatal jaundice, and Neonatal retinal hemorrhage.?
So it's not something to be taken lightly as they are quite serious complications that can arrise. So it is best to avoid an induction at all costs and only used as a last resort before a c/s
