Induction/augmentation of labor

Induction of labor, one of the most commonly performed procedures in obstetrical medicine, can be undertaken for a variety of medical and obstetrical indications. The prediction of labor induction success has been studied with focus on a number of clinical, biochemical, and radiographic approaches. Cervical dilatation at the time of initiation is the best independent predictor of induction success. A variety of pharmacologic and mechanical methods exist for cervical ripening. The most commonly used approaches include use of prostaglandins such dinoprostone and misoprostol as well as transcervical Foley balloon catheter placement. Augmentation of labor is usually accomplished with intravenous oxytocin, which can be administered using either low- or high-dose infusion protocols. In the case of a mid-trimester induction, either induction of labor or dilation and evacuation is considered a safe approach.
