宝妈到了预产期却还没生该怎么办？

发布日期：2024-06-28 10:46:28编辑：秩名


预产期到了还没生怎么办

很多孕妇都会遭遇到这个情况，预产期过了宝宝还是没动静。如果超过预产期怎么办？实际上预产期只是产妇预计生产的日期，并非精确的分娩日期，医生表示在预产期前后两周内分娩，都属正常。如怀孕24-36周间出生视为早产，在42周以后出生，则为逾期产。那么预产期到了还没生怎么办呢？一起来看看医生怎么说吧。
 
1、不要过于紧张，要注意胎动情况。一旦胎动每小时少于3次或在12小时内少于20次或胎动减弱，则需马上到医院作进一步检查，医生会根据情况决定分娩时机。
 
2、继续进行产检，并把孕早期的检查（如B超、验血、妊娠试验等）结果及胎动出现的时间、结果给医生，让医生再次核对孕周。
 
3、加强产前检查，缩短检查间隔时间，随时与医生取得联系，告知宫内胎动情况，同时B超随访羊水量。如果无异常，可在密切监护下继续妊娠。
 
如果预产期推迟到14天后，达到临床所谓过期妊娠时，由于部分孕妇的胎盘会出现老化、胎儿会出现缺氧窒息，所以对孩子的危害较大，应及时到医院采取措施。
 

到预产期不生的原因

医生表示预产期只是产妇预计生产的日期，并非精确的分娩日期，在预产期前后两周内分娩，都属正常。尽管如此，还是有不少产妇想了解到预产期不生的原因是什么。一起来听听医生的解析吧。
 
过期妊娠的病因尚不明确，但医生总结了几个可能引起过期妊娠的原因
 
1、雌激素水平低尽管临产的机制十分复杂，血中雌激素水平的高低与临产有密切关系，过期妊娠可能与血雌激素水平过低有关。但在大数量的过期妊娠中，并无雌激素水平低于普通正常妊娠的直接证明。
 
2、胎盘硫酸脂酶缺乏胎盘硫酸脂酶缺乏(placental sulfatase deficiency)是一种罕见的伴性隐性遗传病，本病由Ryan 1980年报道，患此症者虽然胎儿肾上腺产生了足量的16α-OH-DHEAS，但由于缺乏胎盘硫酸脂酶，无法将这种活性较弱的脱氢表雄酮转变成雌二醇及雌三醇，以致发生过期妊娠。
 
3、头盆不称过期妊娠中部分胎儿较大，胎头迟迟未入盆，宫颈未受到应有的刺激，使产程的开始推迟。这是较多见的原因。
 
4、遗传有少数妇女的妊娠期较长，数胎均出现过期妊娠，有时尚见于一个家族，说明这种倾向可能与遗传有关。
 

过了预产期如何催生

妊娠达到或超过42周(即超过预产期2周)称为过期妊娠。妊娠过期会使胎盘老化，从而使绒毛间隙血流量明显下降，形成梗塞，进一步使血流量减少，供应给胎儿的氧气和营养物质减少，使胎儿不再继续生长。这种情况下需要进行催生，以保证胎儿的健康而安全。那么有什么催生的方法呢？
 
1、运动催生法
 
准妈妈加强运动能促使胎儿入盆，同时还能锻炼盆底肌肉，增加产力。不过，出门运动的时候最好能找个“保镖”，以防突然发生“紧急情况”。医生表示散步能帮助胎儿下降入盆，松弛骨盆韧带，有利于顺利分娩；产前体操在国外非常流行，体操不但可以促使胎头入盆，而且可以增加骨盆底肌肉的韧性和弹性；爬楼梯可以锻炼大腿和臀部的肌肉群，并帮助胎儿入盆，使第一产程尽快到来。
 
2、饮食催生法
 
医生表示，临产时食用冬苋莱粥和空心菜粥，能使孕妈妈更加顺利地分娩，不但加快了产程，也减少了妈妈的痛苦。
 
3、药物催生
 
如果其他方法不能使孕妈妈提早感到阵痛，那么只好用药物催产了。在使用催产素催产前，孕妈妈必须要接受一系列的检查和监测，来评估胎儿状况和胎盘功能。如B超检查能得知胎盘成熟度、羊水量、胎儿大小、脐带血流速度。医生可根据检查结果决定是否需要给准妈妈使用催产素；有经验的产科医师，可通过准妈妈宫颈指诊来评估子宫颈成熟度(子宫颈的柔软度和子宫外口的扩张度)，进而考虑是否早一点接受催生处理。
 

预产期不准该注意什么

在预产期提前让宝宝出生不利于其健康，而过期妊娠，不但不利于宝宝的生长发育，相反得给包包健康带来潜在的威胁。如果预产期不准，产妇应该注意些什么呢？准妈妈们一起来看看吧，多加留心，让宝宝顺利出生健康成长。
 
1、尽早住院，抛弃“妈妈腹中呆一天，胜过外面长三天”的错误观念。　
 
2、确定预产期是否真正过期。平时月经周期不很规则的孕妇更应顾及这个问题。这些孕妇可能由于排卵延迟，而使预产期相应推迟。所以按原先最后一次月经日期而推算的预产期并不是真正的预产期，若在那里随意引产可能会造成早产，影响宝宝的健康成长。此时，准妈妈应准确地向医生提供这次妊娠出现早孕反应、胎动的时间以及怀孕早期B超的检查结果。　
 
3、积极配合医生检查和治疗。一旦确诊妊娠已过期或即将过期，医生会进行一毓检查，了解胎盘功能和胎儿生长情况。若胎盘功能正常，短时间内，胎儿还在继续生长，胎儿面临的危险较小，医生会在严密监视下采取引产的方法；若胎盘功能不良，胎儿停止生长，则胎儿面临死亡的威胁，医生会在短期内进行手术终止妊娠，以确保母子平安。　
 
4、切忌自做主张，干扰医生决定。这样不仅可能延误治疗时机，而且还会影响医生的情绪，对已对宝宝都是极为不利的。
 

孕妇分娩前的症状有哪些

医生表示了解孕妇分娩前的症状表现，可以帮助准妈妈们做好分娩前准备。那么孕妇分娩前的症状具体表现为什么呢？一起来听听医生的解析吧。
 
有规律的痉挛或后背痛：这是子宫交替收缩和松弛所以引起的。随着分娩的时间的推进，这种收缩感会加剧。由于子宫颈的胀大和胎儿自生殖道中产出，疼痛是必然的，不过对胎儿有很大的好处。这种现象只是发生在分娩开始时。胎儿头沉入产妇骨盆，产妇感觉好象胎儿要掉下来一样。这种情况多发生在分娩前的一周或数小时。
 
阴道流出物增加：这是由于孕期粘稠的分泌物累积在子宫颈口，由于粘稠的原因，平时就象塞子一样，将分泌物堵住。当接近生产时，子宫颈胀大，这个塞子就不起作用了，因为分泌物会流出来。这种现象多在分娩前数日或在即将分娩前发生。
 
在分娩前的几天甚至几周里，假宫缩可能会做一些前期准备的工作，让你的子宫颈变软、变薄，也许还会使你的子宫颈稍微张开。如果你生过孩子，你的子宫颈在产程开始前，便有可能会打开1~2厘米。但要知道：如果这是你的第一胎，即使你怀孕40周，你的子宫颈张开了1厘米，也不能保证你马上就要生了。
 
随着分娩的临近，如果你的子宫颈开始张开，你可能会排出宫颈粘液栓——少量稠厚的粘液，在过去的9个月里，它起到密封子宫颈管的作用。这块粘栓可能会一次性成块地被排出，也可能会以增多的阴道分泌物的形式在几天内排出。
