紧急避孕技术应用进展   总被引:18,自引:0,他引:18  
1 紧急避孕 (emergencycontraception ,EC)的定义紧急避孕是指无保护性交后为避免妊娠而临时采取的紧急补救方法。妇女在发现避孕失败或没有避孕措施的性交后可以使用。过去称为“事后避孕”或“晨后避孕” ,均不确切 ,因为补救方法一般在性交后 72h以内或更长些时间内可以使用 ,不一定限于性交后立即使用 ,而且紧急避孕只能偶尔使用 1次 ,不能作为常规。其目的是防止非意愿妊娠 ,而不同于流产[1] 。2 紧急避孕技术应用进展早在公元前 15 0 0年 ,古埃及人就有关于紧急避孕的记载 ,当时的技术多为科学知识与巫术…  相似文献

目的观察目前临床上最常用于紧急避孕的三种方法(米非司酮、毓婷和含铜宫内节育器)用于紧急避孕的临床疗效、不良反应和可接受性。方法采用前瞻性的研究方法,接收符合标准、要求避孕,并愿意参加本课题研究的268例育龄女性。紧急避孕的方法由妇女知情选择,米非司酮组(90例)采用低剂量(25mg)米非司酮单次口服;毓婷组(91例)首次口服毓婷1片(0.75mg),间隔12h后再服1片;含铜宫内节育器(IUD)组(87例),宫内放置Tcu380A--IUD。结果三种方法的有效性分别为86.3%、90.0%和100%,三组均无明显不良反应,仅米非司酮组经期延长显著多于其他两组。米非司酮为处方药,同时发生经期延长的比例高于非处方药的毓婷,因此可接受性不如后者。而对于已经生育妇女,含铜IUD是最有效且可接受性强的紧急避孕方法,但可致盆腔感染则不适用。结论三种避孕方法均安全有效,但在实际应用中,要综合考虑病人的情况,在征得病人同意的情况下合理选择紧急避孕方式。  相似文献

探讨小剂量米非司酮150mg、50mg及25mg应用于紧急避孕的效果.对避孕失败或无避孕措施的性交后72h内就诊的健康妇女6o0例,随机分成3组.Ⅰ组:单次口服米非司酮150mg.Ⅱ组:单次口服米非司酮50mg.Ⅲ组:单次口服米非司酮25mg.结果:Ⅰ组200例.3例妊娠.Ⅱ组200例,4例妊娠.Ⅲ组200例,3例妊娠.均明显低于预期妊娠数(3组相应预期妊娠数分别为17.O30、15.000、14.868),两者之间存在显著差异(P<0.01).避孕有效率Ⅰ组为82.3%、Ⅱ组为73.3%、Ⅲ组为79.8%,3组之间无显著差异.服药后下次月经周期的改变,3组中以Ⅰ组变化较大;Ⅱ、Ⅲ组变化较小,Ⅰ组与Ⅱ、Ⅲ组之间存在显著差异(P<0.01),但3组总共有80.3%月经周期无改变,从总体上看对月经影响较少.仅有4.8%的人有轻微的副反应.表明150mg、50mg或25mg米非司酮作为性交后72h内的紧急避孕是有效的.建议用25mg米非司酮作为紧急避孕药.  相似文献

为探索米非司酮作为紧急避孕的合适剂量,本研究对避孕失败或未避孕同房72 h 内要求紧急避孕的660例妇女,随机单次服米非司酮10 m g 或25 m g。结果:10 m g 组321例中妊娠3例,25 m g 组339例中妊娠4例,均明显低于预期妊娠数,组间差异不明显。避孕有效率分别为88.24% 和83.43% ,副反应轻微。两组分别有14.15% 和21.19% 的服药者周期延长3天以上,组间差异显著(P< 0.05)。本研究提示10 m g 和25 m g 两种剂量的米非司酮皆为合适的紧急避孕剂量。对月经的影响而言10 m g 组优于25 m g 组。  相似文献

Intrauterine contraceptive devices (IUDs) have not suffered from the same negative influences in the developing world as in the first world. The method has too many basic advantages to be gainsaid including, most importantly, that it has the lowest lifetime cost of any effective method of contraception, and that user compliance is not an issue once the device is in place.

However, the global community is not immune from trends that are seen in selected industrialized countries. Today, better methods of contraception are requested and the discomforts associated with earlier models of IUD, which were once acceptable, are less so today. Faced with the side-effects of oral contraception and the high cost in developing countries, many women who have completed their families undergo surgical sterilization as the only long-term method available to them, notwithstanding severe cultural and economic reservations about doing so.

The development of the frameless device is a response to the growing need to develop high-performing, long-acting, reversible and acceptable contraceptives with a high continuation of use and to respond to the urgent need to reverse the legacy of neglect of immediate postabortal family planning.  相似文献

Study Objective and DesignUnintended pregnancy rates in the United States remain high among adolescents. Emergency contraception (EC) provides the only option for pregnancy prevention after unprotected sex. To better define the population of adolescents who request and use EC pills, we performed a post hoc analysis of an over-the-counter simulation study of EC pills.SettingTeen reproductive health clinics in 5 cities.ParticipantsAdolescents between the ages of 13 and 17 years who requested EC.InterventionsSingle-tablet levonorgestrel 1.5 mg.Main Outcome MeasuresWe calculated the correlations between age and baseline sexual and contraceptive behaviors. χ2 Tests were used to compare behaviors of first-time and repeat EC users.ResultsOverall, the most commonly reported contraceptive methods ever used were condoms, oral contraceptives, none, and withdrawal; the most common method ever used in each age group was no method for 13- to 14-year-olds and condom for 15-, 16-, and 17-year-olds. The percentage of participants who had never used contraception before requesting EC decreased with age (53% [20/28] of 13- to 14-year-olds vs 15% [10/65] of 17-year-olds). First-time EC users were more likely to report no previous contraceptive use compared with repeat EC users (42% [88/208] vs 10% [13/135]; P < .001). Regardless of age, the most commonly reported reason for requesting EC was nonuse of any contraceptive method (ie, “unprotected sex”).ConclusionAdolescents who requested EC most commonly reported ever-use of contraceptive methods that rely on user adherence or no method at all, with younger adolescents more likely than older adolescents to have used no previous method. The provision of EC presents an opportunity to provide education and access to highly effective, long-term contraceptive methods.  相似文献

Objective

Emergency contraception (EC) includes hormonal pills (levonorgestrel or ulipristal acetate) and the copper IUD (Cu-IUD). The Cu-IUD is more effective for EC than hormonal pills but remains underused, possibly because of lack of knowledge or interest. The objective of this study was to examine knowledge of and interest in the Cu-IUD for EC among Canadian women seeking EC.

Methods

The study used a cross-sectional convenience survey of English-speaking women presenting for EC at two sexual health clinics in Toronto. The anonymous paper-based survey was completed in the waiting room. The main outcome measures were women’s knowledge of and interest in the Cu-IUD for EC. Demographic and reproductive health data were also collected.

Results

Between January and December 2013, 124 surveys were completed. Mean age of respondents was 26 years (SD ± 6.9). Most were single (85%), and over one half had completed postsecondary education. Overall, 77% had heard of the Cu-IUD, but only 21% were aware of its use for EC. Over 50% were aware that the Cu-IUD is hormone-free and may be used for long-term contraception. Women were less familiar with the window of administration of the Cu-IUD for EC (26%) and its efficacy (6%). In total, 23% (28 of 124) of women were interested in the Cu-IUD, including eight women scheduled to receive one that day.

Conclusion

Women presenting for EC were unaware of the Cu-IUD but were moderately interested in it once informed. Public education and routine counselling about the Cu-IUD at EC visits may increase the uptake of this method.  相似文献

人工流产妇女的紧急避孕知识水平及其影响因素分析   总被引:5,自引:2,他引:3  
赵双玲  楼超华  高尔生 《生殖与避孕》2000,20(6):360-367,378
本文分析了上海市三所妇幼保健院606名人工流产妇女的紧急避孕知识。结果表明:妇女对紧急避孕法的客观需求高,但知识水平低。妇女有关紧急避孕的知识主要来源于书报杂志和亲友。28.5%的对象知道紧急避孕法,多数知道的是激素类紧急避孕药,但其中只有14.9%知道其使用有效时间为性生活后72 h以内。知晓者的平均知识得分不足满分的一半。知识来源于计划生育宣教资料的对象知识水平较高。文化程度低的妇女不仅知晓率低,其紧急避孕的知识水平也低。结果提示:为减少非意愿妊娠和人工流产,迫切需要加强紧急避孕的知识宣传。应用通俗易懂的语言详细说明方法的适用情况、优缺点和注意事项。计划生育部门在知识的传播中应起重要作用。  相似文献

三种不同剂量的米非司酮作为紧急避孕药的研究   总被引:5,自引:2,他引:3  
本文对三种不同剂量的米非司酮作为紧急避孕药进行了比较研究.240例健康妇女被随机分配在三种剂量组:10mg、50mg和600mg.服药后有1例失败.此例为10mg组,同房与服药时间相距为84.5h.三组恶心与呕吐等副反应发生率基本相似.但对月经周期影响各不相同.剂量越小对月经周期的干扰越小.引起月经延迟(比预计月经迟≥4天),10mg、50mg和600mg三组分别为21例(28.4%),34例(42.5%)及45例(60%),平均延迟时间600mg组为9.8土11.1天,明显大于10mg和50mg组(2.3土0.8天,5.7±11.3天).同时在月经不同时相服药对月经干扰也不一样.在黄体期服药者延迟月经的例数多,天数长.以上结果提示,小剂量的米非司酮10mg与600mg米非司酮一样可以作为紧急避孕药使用,而且副反应小.但如何克服服用米非司酮作为紧急避孕药后月经的延迟仍是一个值得研究的问题.  相似文献
