发布日期：2022-10-04 18:00:33编辑：美清

带环妊娠中生化妊娠占妊娠的4%上下，高过未带环者，故产生带环妊娠后，最先要作B超查验以外生化妊娠。若为宫腔内妊娠，则其流产发病率较高，产前后左右流血、胎死腹中、早产儿者也多。

带环怀孕的小孩可以要吗？

宫腔内节育器是一种安全性、简单、经济发展、合理的避孕的方法，备受众多女性钟爱，在我国有50%之上的女性在应用宫腔内节育器。殊不知，一切一种避孕方法的避孕措施通过率都未做到100%，宫腔内节育器的避孕措施通过率约在85%-90%上下，换句话说，大概有10%—15%的女性会产生带环妊娠或脱环妊娠。

带环后妊娠的缘故

1、节育器脱落。宫腔内节育器对孑宫而言是一种脏东西，它能促进宫缩，使节育器下沉脱落。伴随着时间流逝，孑宫慢慢融入了这类刺激性，排异性朋友降低，脱落率就减少了。据调查，脱落率以上环后一个月内为最大，约50%的脱落产生在前3个月内，之后各月保持稳定，大部分脱落是产生内行生理期。一般年纪轻、产次少或哺乳期间的女性，很有可能因孑宫全身肌肉延展性好及较比较敏感而易脱环；子宫颈口松驰或有子宫下垂者也易脱环。此外，节育器过大、过小或手术中未将其放进宫底也会使节育器脱落。

2、节育器下沉。节育器脱落到子宫口，而起不上避孕措施实际效果。

3、环的型号规格与宫腔内尺寸不宜，或环有歪曲、形变，起不上避孕措施的功效。

4、某些女性放置节育器后，子宫壁沒有造成相对应的机构反映，或精卵结合未遭受受精卵着床的阻拦，很有可能再孕期。

避免带环妊娠或脱环妊娠要留意以下几个方面

1、放置后尽可能歇息，不要在放置的三天内就走远路、体力劳动活以下蹲、扛重物品等，以防导致腹腔工作压力过大，将宫腔内节育器挤压。

2、放置宫腔内节育器的前三天与后两个星期内要防止行房，由于夫妻生活非常容易造成宫缩。

3、放置初期要留意节育器是不是脱落，在月生理期应仔细查询月经中是不是有避孕环滑脱。如避孕环放置后发生腰酸背痛、下腹坠痛、月经流血不干净等，应立即到医院作查验，是不是节育器脱落或下沉。并在宫腔内放置避孕环后第一、第三及第六个月各自到医院门诊复诊，之后也每一年最少找妇科大夫复诊一次。

4、发觉节育器脱落，如果没有其他忌讳，再度上环，一定要拆换号与种类。不断脱落者，要改成其他避孕的方法。

5、月历经期要当心孕期，应尽快去医院检查以诊断。

产生带环妊娠或脱环妊娠如何处理

带环妊娠中生化妊娠占妊娠的4%上下，高过未带环者，故产生带环妊娠后，最先要作B超查验以外生化妊娠。若为宫腔内妊娠，则其流产发病率较高，产前后左右流血、胎死腹中、早产儿者也多，并有挤压、危害胚胎发育过程的很有可能，且有报导发觉环形环套于胚体的。故大部分人认为对带环妊娠者以尽快停止妊娠为宜。因妊娠三个月之内的人工流产对身体危害较小，因此 ，执行人工流产越快越好。因独特缘故早已超出三个月者，也务必尽快到医院门诊，由医师给与中期引产等妥善处置。
