探讨人工流产术后使用短效口服避孕药的临床意义。

选取在本院行人工流产术的健康妇女200例，随机分为观察组(n＝100)与对照组(n＝100)(分组征得患者本人的知情同意)。观察组于人工流产后第1天开始口服短效避孕药(去氧孕烯炔雌醇片)，每天1片(含去氧孕酮150 μg 、炔雌醇30 μg)，连服21 d为一个周期，停药8 d，随后开始第2周期(剂量同前)，共服用6个周期；对照组采用其他方法避孕(如安全套等)。两组均于人工流产术后开始口服抗生素抗感染与宫缩剂止血(口服7 d)。观察两组阴道出血量及持续时间：从人工流产术后的第1天开始记录；超声评价：于人工流产术后第20天行超声检查，了解子宫内状况(是否占位等)和子宫内膜恢复情况；有无盆腔炎，如腹痛、发热、阴道分泌物异常等；月经周期的恢复情况：包括月经是否规律、经量等，观察期为6个月；避孕效果：再次妊娠率；避孕药的不良反应：包括恶心、头痛、乳房胀痛、阴道点滴出血、体重改变等。

人工流产术后，观察组阴道出血量及持续时间、子宫内状况、月经周期恢复情况、避孕的效果优于对照组(P<0.05)；两组盆腔炎的发生率比较，差异无显著意义(P>0.05)。口服短效避孕药无明显不良反应。

人工流产后使用短效口服避孕药安全、有效，能明显减少术后阴道出血量及缩短阴道出血持续时间、迅速使子宫内膜修复、恢复月经周期，避孕效果显著。由此可见，人工流产后使用短效口服避孕药，是人工流产后计划生育服务(post－abortion family planning care，PAFPC)的核心内容，在促进妇女生殖健康方面有重大意义，值得推广。

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.

Using oral contraceptive after abortion is effective and safe, which significantly prompts the reproduction health of women.
