IntroductionVarious reasons can lead to abortion in the second trimester of pregnancy. Abortion in the second trimester of pregnancy causes significantly more complications like hemorrhage and placental retention as compared to the abortions occurring in gestational ages less than 8 weeks. In order to control and improve the third stage of labor, several medications derived from oxytocin, ergots, and prostaglandin groups can be used orally, vaginally, and rectally (1-5). Rectal, vaginal and oral misoprostol can be used for controlling hemorrhage in the third stage of delivery. Rectal administration of misoprostol has the advantage of having high level of absorption in the body and fewer complications in comparison to its oral form. Cases of retained placenta in different studies have been reported between 8%-80% (6,7). The aim of this study was to compare the efficacy of intravenous oxytocin versus rectal misoprostol in the management of the third stage of labor during pregnancy termination.
Materials and MethodsIn this randomized clinical trial, 100 women with gestational age of 14-28 weeks, visiting for terminating the pregnancy due to intrauterine fetal death (IUFD) or approved premature rupture of membrane (PROM), entered the study. After being informed about the possible abortion procedures, medications, side effects and methods of implementation, they completed the consent form and were divided into two groups of 50 patients each by random selection methods (by selecting one of the red and blue cards). All women in the two groups (oxytocin and misoprostol) underwent the same protocol of receiving 200 µg vaginal misoprostol every 6 hours. In case of having cesarean, lower doses of misoprostol were administered, which lasted for 24 hours, and if no response was received, it would be continued for the next 24 hours. After 48 hours, while considering the condition of the cervix and its dilation, other methods such as putting catheter into the cervix or using high doses of oxytocin would be used. After recording the time of fetal expulsion, intravenous oxytocin including 40 units of oxytocin in a liter of normal saline during one hour was administered to one group and 400 µg of rectal misoprostol was administered to the other group. We had 1 hour to register the time of placenta expulsion and during this time the patients were monitored every 15 minutes and their vital signs including blood pressure, heart rate and the amount of bleeding based on the number of consumed pads, fever, chills, diarrhea and vomiting were checked and recorded. If placental expulsion did not occur in an hour or the vital signs of mother were unstable, or vaginal bleeding was severe, the patients would undergo curettage and the uterine contents would be removed and sent to pathology.
