摘要
目的:观察产后哺乳妇女首次排卵日,了解产后哺乳妇女卵巢变化及子宫体复旧情况,为产后哺乳妇女避孕节育措施的应用提供科学数据。方法:连续腹部B超探查101例产后哺乳妇女子宫体复旧、卵巢变化及排卵情况,辅以基础体温(BBT)测量及宫颈粘液评分。结果:53例(52.5％)B超监测到大于1.8cm卵泡,平均在产后154天(5.1个月),其中32例(60.4％;32/53)卵泡大于1.8cm后萎缩,结合BBT及宫颈粘液评分,提示排卵多为黄体功能不全。产后4个月内B超监测首次排卵为10.9％(11/101),4个月后排卵率为41.6％(42/101)。给婴儿添加辅食时间与月经复潮时间及首次排卵时间呈显著正相关(n=100,r=0.4764,P<0.01及n=53,r=0.5554,P<0.01)。产后61～90天(B组)子宫体明显比42～60天(A组)减小,91～120天(C组)及121～150天(D组)均明显比A组和B组减小(P<0.05～0.01),而151天以后各组(E组、F组及G组)间比较均无明显差异,但均明显小于A、B、C、D各组(P<0.01)。卵巢B超测量,产后151～210天(C组)及210天以上(G组)两组均明显比A组和B组增大。结论:添加辅食对产后月经复潮及排卵有较大影响。建议产后妇女在母乳喂养为主的情况下,自行选择避孕措施以产后60天为宜,落实具体实施情况应在产后4个月开始;延长母乳喂养时间是一种有效的避孕方法。产后哺乳妇?
Objective;To monitor the first ovulation,uterine involution and alteration of ovary in post-partum women,and to provide science data for contraception in postpartum lactating women. Methods : Form January 1996 to December 1998, one hundred and one postpartum women continuously monitored ovulation,uterine involution and alteration of ovary by ultrasound,and basal body tempera-ture(BBT) and cervical mucus were investigated. Results : There were 53 (52. 5% , 53/101 )subjects monitored by ultrasound. The first ovulation (follicle>1. 8cm in diameter)was observed and the mean time of ovulation was 154 days(5.1 moths)postpartum. Follicles in 32 of 53 monitored ovulation were atrophic. referring to BBT and cervical mucus,60. 4% of the first ovulation had Luteal phase defects. There were 11 subjects (10. 9% , 11/101) who were monitored the first ovulation during the first 4 months postpartum and 42 (41. 6% , 42/101)ovulation were monitored after 4 months postpartum. Significant positive correlation was found among the time of supplementary feeding,the time of the first menses(n=100,r=0. 4764,P<0. 01)and the time of the first ovulation(n= 53,r = 0. 5554,P< 0. 01). From 42-60d to 121-150d postpartum,uterine involution was slow (from 6. 35cm × 5. 66cm ×4. 17cm to 5. 17cm × 4. 17cm×3. 32cm,P<0. 05-0. 01). The size of the ovary during 151-180d postpartum was larger than that of before 150d postpartum,the means of the left ovary length and width were from 2. 18cm×1. 61cm on 42-60d to 2. 36cm×1. 75cm on 151-180d(P<0. 01)and that of the right were from 2. 30cm×1. 65cm on 42-60d to 2. 49cm×1. 78cm on 151 ×180d(P<0. 01). Conclusion: The frist menses and the first ovulation were influenced by supplementary feeding in postpartum lactating women. Uterine involution was slow before 4 months postpartum and then returned to the non-pregnant uterus. The size of ovary was increased 5 months postpartum,and it may be related to ovulation. It is suitable to start selecting birth control methods by oneself 60 days postpartum and to pr
