[Continuous extra-amniotic intracavitary application of prostaglandin F2 alpha for medicamentous induction of labour in high-risk cases of pregnancy interruption].

Reported in the paper is continuous extra-amniotic application of Prostaglandin F2 alpha (PG F2 alpha) to 70 juvenile primigravidae for termination of pregnancy. Successful priming was achieved in 54 patients after three and a half hours of induction, following administration of an average induction dose of 3 mg PG F2 alpha. Induced abortion was "incomplete or retained" and, therefore, stopped in 16 cases. An account is given of advantages of the above approach over intermittent intra-uterine application. The technique described in this paper was found to be suitable and commendable for minimizing of side-effects and risk as well as for better and individual controllability. It has also proved to reduce the variety of contra-indications to prostaglandin induction for patients with pre-existing diseases. Continuous intracavitary induction of labour may be considered as a justified alternative to the risks implied in other techniques of interruption.
