Abstract:
Extra-amniotic ethacridine lactate plus intramuscular prostaglandin has become a popular method for terminating second trimester pregnancies. In this study, intrauterine pressure was continuously monitored in order to objectively compare the efficacy of 3 different times of administration of Carboprost (15-methyl PGF2 alpha) - at 2 hours, 4 hours and 8 hours after the instillation of ethacridine lactate. The best results were obtained with the administration of Carboprost 8 hours after the instillation of the extra-amniotic ethacridine lactate. The synergistic effect of ethacridine lactate and Carboprost is optimal after this time. This is probably because the ethacridine lactate will have produced sufficient cervical ripening to ensure optimal efficacy of the prostaglandin-induced uterine contractions in expelling the products of conception.
