Oral prostaglandin E2 for induction of labor at term. II. Comparison of two low-dosage regimens

Abstract

Prostaglandin E2 was administered orally for induction of labor in 100 normal term gravidas with two dosage regimens. The data derived were compared with comparable data from gravidas matched with study patients according to prelabor cervical preparation and other relevant obstetric and actuarial features. Analysis of patterns of cervical dilatation and station vs. time was carried out. A dose of 0.5 mg. hourly was found to be effective in inducing labor of good quality with minimal side effects, providing a better balance between efficacy and adverse reactions than the higher dosage level.
