Study type
Description of intervention(s) / exposure
The patients were interviewed at the outpatient clinic or the delivery ward ,where full detailed history was taken and examination confirming the pregnancy and gestational age based on the last menstrual period or documented early ultrasound report. Abdominal ultrasound was performed in the clinic to determine gestational duration using femur length as parameter (Hadlock system), after having confirmed the pregnancy, the gestational age and fetal death, women were informed about the nature of the study and of the possible risks and benefits. Informed written consent was obtained from each participant.

The study had 2 treatment groups . group I received a dose of misoprostol (200 microgram)(one tablet of Misotac 200 ug ; Sigma co.,Cairo, Egypt) every 4 hours buccally (and the subject was instructed not to swallow it for one hour) till expulsion of the fetus for maximum 24 hours .
Group II received a dose of moistened misoprostol (200 microgram) (one tablet of Misotac 200 ug ; Sigma co.,Cairo, Egypt) every 4 hours vaginally(tablet was put into the posterior fornix)till expulsion of the fetus for maximum 24 hours.
Follow up
Subjects were asked about onset and degree of pain and examined every 4 hours for blood pressure , pulse and temperature, and were examined vaginally every 4 hours to assess progress of cervical opening and presence of vaginal bleeding up to fetal expulsion .
Once fetal expulsion occurred, the patient received a dose of oxytocin , 10 U in 500 mL of lactated Ringers by iv infusion till delivery of the placenta. Removal of the placenta by surgical dilatation and evacuation was performed immediately in case of heavy bleeding ,or if it was retained following fetal expulsion more than half an hour (as recorded by E Alston RM, 2012).
Antibiotic therapy prescription as a part of the hospital protocol was given to all women post abortive before discharge and antibiotic plus treatment for inhibition of lactation drug was prescribed as a home treatment .
hemoglobin level was done for all women before ,and 12 hours after complete expulsion.
Data collection include the demographics ( the women's age, gestational age, gravidity, parity and previous misscariage) , number and timing of misoprostol doses and the induction-expulsion time interval.
All women were followed for side effects such as nausea, vomiting , diarrhea and fever and reported.

Sample Size Calculation
According to a recent study the median time to expulsion in the vaginal misoprostol and buccal misoprostol groups was 12 and 15 hours respectively with difference 3 hours in time interval
A power calculation estimated that in order to detect an effect size of 0.3 of the regression of time interval of abortion with misoprostol via vaginal compared to buccal route among women indicated for abortion in the second trimester of pregnancy with a p value < 0.05 and 95% power, a sample size of 180 patients (90 for each group) is needed. G*Power software was used for sample size calculation

Analysis of the data was performed by SPSS, version 8 for windows (10). Categorical and ordinal data were presented as ratios, whereas continuous data were presented as means + standard deviation.
