The force required to remove the frameless 0-suture IUD anchoring system: comparison between pre- and postmenopausal women

OBJECTIVE: The objective of this short communication is to measure and compare the force needed to remove the implanted "0-suture" GyneFix intrauterine contraceptive device (IUD) and the "0-suture" FibroPlant trade mark -LNG intrauterine system (IUS) from the uterus of pre- and postmenopausal women. STUDY DESIGN: A nonrandomized comparative study in 119 pre- and postmenopausal women. A dynamometer (Pesola) was used to measure the removal force in newtons. RESULTS: The results of this study show a mean removal force of 8.5 and 9.5 newtons, respectively (range, 3-11 and 4.5-11), in pre- and postmenopausal women, which is significantly different (p = 0.003). CONCLUSIONS: The force needed to remove the IUD/IUS anchored in the myometrium of the uterine fundus of pre- and postmenopausal women is higher than the removal force found in previous studies in which the IUD consisted of a slightly thinner anchoring thread (00 instead of 0 suture). The statistically significantly different removal force between the two groups has no clinical implications. The difference may reflect the increased compactness of the uterine tissue in the postmenopausal uterus.     

米索前列醇在绝经后妇女取出IUD的临床应用

宫内节育器(IUD)具有安全、有效、简便、经济、长效等特点,是育龄妇女较为理想的避孕工具。绝经后妇女因卵巢功能减退,雌激素水平低,生殖器官萎缩,特别是宫颈萎缩,穹隆消失,给取出IUD造成一定困难。自2003年开始,已绝经的老年妇女来我站取IUD明显增加,为了减轻其痛苦,降低取IUD     

未婚未产女性GyneFixIN宫内节育器取出困难16例临床分析

目的 探讨未婚未产女性吉妮环取出困难的原因、处理方法及预防措施。方法 术前阴道放置米索前列醇0.4mg，术中运用异丙酚无痛取环。采用回顾性分析其取器困难的原因，以探讨预防措施。结果 16例均顺利取出，宫口未见节育环尾丝。术中出血量少于10ml。术后无并发症。结论 未婚未产女性应尽量避免采用节育环避孕，且尾丝不宜过短。积极治疗妇科炎症是预防节育环取出困难得重要措施。     

卵巢妊娠17例的临床分析

原发性卵巢妊娠是一种罕见的异位妊娠,其发病率为1/(900～6 000),占异位妊娠的0.36%～2.74%。本文对我院近年来收治的异位妊娠病例进行回顾性分析,现报道如下:     

Experience with Lippes loop and copper-T intrauterine devices in rural Bangladesh

Experience with IUD use among rural Bangladeshi women within two programmatic efforts demonstrates that the Copper-T IUD suited the needs of younger, lower-parity women better than Lippes Loop. The differential performance by the device was especially marked within the program that offered a broad selection of contraceptive methods and occurred mainly because of lower rates of expulsion and lower rates of discontinuation for bleeding and pain among the Copper-T users. Nevertheless, the easy availability of a wide choice of methods during the second program successfully encouraged dissatisfied IUD discontinuers to try other methods of contraception.     

固环胶囊对宫内节育器大鼠血浆及子宫组织内皮素含量的影响

目的研究固环胶囊治疗宫内节育器致出血副反应的疗效及其作用机理。方法对宫内节育器大鼠模型灌服固环胶囊,10 d后取血和子宫组织,检测内皮素的含量。结果固环胶囊有升高宫内节育器大鼠模型血浆及子宫组织内皮素的作用,与模型组比较有显著性差异(P<0.05)。结论固环胶囊可能通过调节机体内皮素的含量而收缩血管,减少子宫局部血流量,从而达到治疗置器后月经过多、经期延长的目的。     

社区放置宫内节育器围绝经期妇女调查分析

目的提高放置宫内节育器（简称IUD）围绝经期妇女的自我保护意识和生殖健康水平，并探索建立科学的生育关怀长效机制。方法自2003～2005年，对居住本辖区内的1690名45～49岁放置IUD妇女上门采用问卷方式予以放环情况调查，针对不同情况和对象给予每年1～2次的个性化分类指导和随访干预。结果通过对286名对象的跟踪随访和干预，使67．9％的环超有效期对象取、换环；83．3％不了解环型的对象检查了环；70．6％绝经未取环的对象已取环，总的随访干预落实率达到70．6％。结论通过该项目的实施使我们进一步认识到：一是计划生育后续服务的重要性；二是促进妇女自我保护意识；三是必须开展以人为本的计划生育优质服务，并建立长效机制。     

剖宫产术中放置吉娜IUD后产褥出血量及恶露持续时间的观察

目的:观察剖宫产术中放置吉娜固定式宫内节育器(GyneFix PP IUD)对产时、产后出血、恶露持续时间及子宫复旧的影响。方法:对200例剖宫产放置吉娜IUD和204例剖宫产未放IUD妇女产时、产后出血量,产后恶露持续时间进行比较,并B超复查产后42天、90天时子宫复旧情况及吉娜IUD的状况。结果:两组产后出血量、恶露持续时间无显著差异,子宫复旧正常。在产后42天复查时吉娜脱落率为4％。86％的妇女可在宫颈见到吉娜尾丝。结论:剖宫产术即时放置吉娜IUD是安全的,未增加产后出血量及恶露持续时间,不影响子宫复旧,为产后即时避孕提供了新的选择。     

剖宫产妇女放置两种IUD临床效果观察

目的 :观察剖宫产妇女放置新型GyneFixIN宫内节育器 (IUD)的临床效果。方法 :采用随机对照临床研究方法 ,对 195例有剖宫产史的健康妇女于月经后或人工流产术毕即时放置GyneFixINIUD 99例 (吉妮组 )及TCu2 2 0CIUD 96例 (TCu2 2 0C组 ) ,于放器后 1、3、6、12和 2 4个月随访 ,以生命表法统计两种IUD的终止情况。结果 :吉妮组使用 2年脱落率和因症取出率分别为每百妇女 1.0 1和 2 .0 2 ,明显低于TCu2 2 0C组的每百妇女 10 .4 2和 8.33(P <0 0 1)。结论 :GyneFixINIUD无支架 ,铜表面积大并固定于子宫底 ,更适合有剖宫产史妇女放置
