Mifepristone alone versus mifepristone-misoprostol combination regimen for management of intrauterine fetal death

Abstract

Background: Early pregnancy failure is a common complication of pregnancy. If women do not abort spontaneously, they will undergo medical or surgical treatment in order to remove the products of conception from the uterus. Curettage, although highly effective, is associated with a risk of complications; medical treatment with misoprostol is a safe and less expensive alternative. Unfortunately, after 1 week of expectant management in case of EPF, medical treatment with misoprostol has a complete evacuation rate of approximately 50%. Misoprostol treatment results may be improved by pre-treatment with mifepristone; its effectiveness has already been proven for other indications of pregnancy termination. The study objective was to compare the outcome of Mifepristone alone with the Mifepristone- Misoprostol combination regimen for the management of IUFD.Methods: This was a Prospective clinical trial at the department of obstetrics and gynecology, Chittagong Medical College Hospital, Chittagong. From March 2016 (Actual patient enrolment started after obtaining ethical clearance i.e. March 2018) to September 2018.Results: A subjects delivered earlier than group B and the mean induction delivery interval in Group A is significantly less in comparison to Group B (p=<0.001). Out of 50 women, 2(4%) and 10(20%) women in Groups A and B required oxytocin infusion to establish good contractions, and completion of termination who regarded as a failure. In the mifepristone alone group, the success rate is significantly higher than in the combination group.Conclusions: The efficacy of mifepristone alone was found superior to that of the mifepristone misoprostol combination regimen in the present study.
