預(yù)產(chǎn)期推遲是什么原因？相信孩子在預(yù)產(chǎn)期當(dāng)天出生的情況并不多見(jiàn)，而事實(shí)上許多寶寶都是在預(yù)產(chǎn)期前后出生的。對(duì)于一些沒(méi)有生育經(jīng)驗(yàn)的爸爸媽媽來(lái)講，若是到了預(yù)產(chǎn)期寶寶沒(méi)有任何反應(yīng)的話，他們一定是心急壞了。他們會(huì)擔(dān)心寶寶是否有危險(xiǎn)，寶寶是否缺氧，寶寶是否發(fā)育不好，寶寶是否------

那么，是什么原因造成的預(yù)產(chǎn)期推后呢？預(yù)產(chǎn)期過(guò)了還沒(méi)生要怎么辦才好呢？對(duì)于準(zhǔn)爸爸準(zhǔn)媽媽來(lái)講，學(xué)習(xí)一些有關(guān)的分娩常識(shí)是很有必要的，為了寶寶能夠平安順利出生，為了孕媽媽能夠順利分娩，這些知識(shí)真的是很有必要提前掌握的哦。

預(yù)產(chǎn)期推遲是什么原因

預(yù)產(chǎn)期推遲是什么原因？

一、胎頭未入盆

如果胎兒個(gè)頭較大，胎頭沒(méi)有及時(shí)入盆，對(duì)宮頸的刺激不夠，產(chǎn)程因而會(huì)延長(zhǎng)。

二、胎兒發(fā)育異常

懷有無(wú)腦畸形胎兒或羊水過(guò)多時(shí)，子宮不能受到有效刺激，引發(fā)規(guī)律性宮縮，因而遲遲不生。

三、孕晚期活動(dòng)少、營(yíng)養(yǎng)攝入多

孕晚期準(zhǔn)媽媽的活動(dòng)量少，營(yíng)養(yǎng)攝入量太多，是誘發(fā)過(guò)期妊娠的原因之一。

四、預(yù)產(chǎn)期不準(zhǔn)

預(yù)產(chǎn)期并不是標(biāo)準(zhǔn)的生產(chǎn)日期，到了預(yù)產(chǎn)期還不生很常見(jiàn)。臨床統(tǒng)計(jì)，只有53%左右的孕婦在預(yù)產(chǎn)期那一天分娩。就醫(yī)學(xué)觀點(diǎn)來(lái)看，預(yù)產(chǎn)期前2周或后2周內(nèi)分娩，都屬于適期分娩，為正?，F(xiàn)象，孕媽媽不必?fù)?dān)心，再等待幾天看看。

五、遺傳因素

有少數(shù)婦女的妊娠期較長(zhǎng)，數(shù)胎均出現(xiàn)過(guò)期妊娠，有時(shí)尚見(jiàn)于一個(gè)家族，說(shuō)明這種傾向可能與遺傳有關(guān)，超過(guò)預(yù)產(chǎn)期2周要入院處理。
