title: [Induction of labour: which method to use?].
abstract: Induction of labour is a common obstetric instrument to employ when the potential risk to continue a pregnancy is higher than to terminate it. The methods of induction can be pharmacological or mechanical; the choice of the method mainly depends by the cervical ripening, as it is significantly able to influence, according to the type of induction, its final issue. The mechanical methods are: stripping and sweeping of the membranes, hand dilatation of cervix, intrauterine pressure catheters, Laminaria Japonicum, transcervical Foley catheter and amniotomy. To pharmacological methods include some agents such as the prostaglandins (PG), the most common approach to induce a labour, and used above all by vaginal way in patients with unripe cervix. They simulate the natural PG effects at the beginning of delivery and show a great efficiency. There are a lot of PG on the market, but except some of them, as Dinoprostone for PGE2 and Misoprostol for PGE1, no one of them shows the same safety in management of labour. Oxytocin, another inductive method, administered by diluted intravenous infusion, is utilized alone or mainly with other methods when the labour is started or with rupture of the membranes, because it begins or maintains the myometrial contraction.
