ABSTRACT
To compare the efficacy of two routes of prostaglandin E2 administration [Intravenous and Intramuscular] for treatment of missed abortion this study was conducted. Regarding the pilot cases of missed abortion admitted for termination of pregnancy intravenous administration of PGE2 that had higher efficacy compare to intramuscular route, investigators designed this study. In a randomized clinical trail, 50 women with confirmed missed abortion received 250-500 ?g prostaglandins E2 either intravenously or intramuscularly. Evacuation time set from drug injection to complete empting of uterus. Complete uterine evacuation was defined as empting of uterus from pregnancy materials without the need for surgical intervention and partial evacuation defined as incomplete empting of uterus that need further surgical management. Data were analyzed using SPSS, version 13. All the data extracted with a checklist and compare by descriptive statistics and X2 and t-tests. There was no statistically difference between the results of two administration routes. The mean of evacuation time in intravenous administration routes was significantly lower in compare to intramuscular administration routes [P < 0.5]. There was no statistically significant difference in the demographic data in two groups. There was no preference between two administration routes except for evacuation time that occurred more rapidly in intravenous administration of PG E2
