The review findings suggest three effective methods for cervical ripening: misoprostol, osmotic dilators, and mifepristone. Induction of labor (IOL) is the process of initiating labor by using medications, mechanical (devices), or other methods, with a goal to achieve safe vaginal birth.1 IOL has shown maternal/child benefit when the health of a pregnant woman or fetus is at risk (e.g. The outcome variables of interest were Bishop score upon removal of the … The nature of the cervix is therefore crucial in determining whether labour and delivery is likely to be successful.
