Managing post-term pregnancy.

The optimal management of post-term pregnancy (gestation lasting 42 weeks or more) is not resolved. The risk to the fetus increases as pregnancy continues post term and this has to be balanced against the risks associated with induction. Here we consider whether routine induction at around 42 weeks has any advantages over expectant management, in which pregnancy is allowed to run its natural course unless the fetus (or mother) develops features of distress.
