Letrozole Pretreatment With Misoprostol Versus Misoprostol Alone For Induction of First Trimesteric Missed Miscarriage A Randomized Controlled Trial
Abstract Background Miscarriage or spontaneous abortion is the involuntary termination of pregnancy before 20 weeks of gestation or a fetus born weighting less than 500 grams. Objective To compare between the safety and efficacy of two treatment modalities in medical termination of first trimesteric missed miscarriage. Patients and Methods This study was conducted at outpatient Obstetric clinic of Ain Shams maternity hospital in the period between June 2017 and December 2018. The patients who were fulfilling the inclusion criteria, were recruited in the study, then an informed consent was taken before starting the trial. Results In the total of 88 patients who were recruited in the study, 3 patients dropped from the study, 2 patients from the first group and 1 patient from the second group, so 85 patients were analyzed, the complete abortion rate of the letrozole group was significantly higher than that of the misoprostol only group (83.72% compared to 64.29%). Conclusion The use of letrozole pretreatment followed by misoprostol for induction of abortion in the first trimester is associated with higher complete abortion rate than misoprostol only.
