It has been known for years that prostaglandins can be used to bring on labor. The authors experienced with alpha PGF2 by extraamiotic, intracavitary infusion. The group of 23 patients included 20 cases of incomplete abortion in the second trimester, 9 cases of intrauterine fetal death in the third trimester, and 1 case of vesicular mole. This method proved 82.6% successful: in 56.9% of cases the product of conception was expelled within 12 hours; in 26.5% of cases within 24 hours. Only in 4 cases, 17.4%, this method proved unsuccessful; oxytocin was used in 3 of these 4 cases. Hypertonia was evident immediately after infusion; uterine contractions, measured and registered with a tocograph, were frequent and increasingly intense. Nausea, vomiting and diarrhea were observed in 26.5% of cases; 1 patient had facial flush. These side effects were probably due to the low absorption of the drug into the circulation. Results obtained confirm others described in the literature on the subject.

The efficacy of intramuscular administration of 15 methyl (15S) prostaglandin F2alpha (PGF2a) in midtrimester pregnancy termination was evaluated in 16 healthy patients (mean age, 23.3; mean parity, 1.4; mean number of menstrual weeks, 16.1) by measuring dose response; oxytocin conversion; abortion time; side effects; intrauterine dynamics and progesterone withdrawal. Labor was monitored using extraovular balloon placed transvaginally; transcervically; and connected to a Physiograph machine. Patients not aborting within 48 hours after the first dose were considered failures. Blood samples were collected at 0, 3, and 6 hours and at abortion time for plasma progesterone measurement. Average dose given was 789 +or- 60 micrograms. Only 9 of 10 patients aborted within the prescribed 48 hours: 7 were complete abortions, and 2 were incomplete and required suction curettage. Mean induction to abortion time was 20.2 +or- 2.7 hours. Nausea, vomiting and diarrhea were the main side effects. The findings suggest that 15 methyl PGF2a in the dosages and routes prescribed is not as efficient as PGF2a. It is also suggested that prostaglandin affects the myometrium at 2 levels: 1) a membrane effect, and 2) a more fundamental intracellular regulatory effect which is necessary to initiate labor.
