In a randomized controlled trial foley catheter under traction (group B) is compared with 2,5 mg extra amniotic prostaglandin F2 alpha in 20 mls of tylose gel (group A) to ripen the cervix in a group of 77 patients undergoing induction of labour. The two groups were found to be comparable in terms of patient characteristics, mean initial cervical scores, infant birth weight and indications for induction. Fourteen patients in group A went into spontaneous labour and 9 of these did not require augmentation with oxytocin as opposed to 2 patients and 3 patients, respectively in group B and in group A. However, the duration of first stage, the amniotomy delivery interval, mean oxytocin dose required, mode of delivery and infant outcome were not significantly different between the two groups. Although the results of the trial have shown that prostagladin gel is more effective than foley catheter in ripening the cervix, the latter is certainly effective and innocuous. It is also cheap and easily available, and in developing countries this may be of vital importance. A modification of the method possibly using two insertions prior to amniotomy, may increase its effectiveness further.
