To assess the clinical value of using oral contraceptive pills(Mircette) in a short-term effect after abortion.

200 cases with early pregnancies were randomly divided into the observed group(n=100) and the control group(n=100) (Informed consent was obtained from all participants). The mircette(desogestrel 150 μg, ethinyl estradiol 30 μg) were used at the first day after abortion in the observed group in the first stage (1#qd po, for 21 days), and the next following stage would start at the eighth day of first stage completion (prescribed as the first period). Six periods were observed. The other contraceptive methods instead of taking oral contraceptive were used in the control group(eg.condom). The antibiotics and uterotonic were used in both groups for 7 days. The following items were observed, ① The time and amount of bleeding after aborting were recorded. ②Ultrasonic evaluation was used for the status of uterine at 20 th days. ③ Symptoms of pelvic inflammatory, as bellyache, fever, abnormity of vaginal secretion, and so on. ④ menstral cycle: 6 months were observed.⑤Pregnant rates were recorded.⑥The side effects of oral contraceptive, including nausea, headache, bubby pain, bleeding of vaginal, and change of avoirdupois.

The average amount of post-abortion bleeding in the observed group was less than that in the control group (P<0.05). The average bleeding time of the observed group was shorter (P<0.05). The status of uterine, menstruation and effects of oral contraceptive in the observed group were better than that in the control group. The rate of pelvic inflammatory disease had no significant(P>0.05). There were no obvious side effects in the observed group.
