許多孕婦其實對於胎盤的周胎成熟度是沒有概念的,不知道胎盤的盘成成熟度和孩子的發育會有什麽關係。胎盤1級和2級對於胎兒來說都是熟度可以正常發育的,如果胎盤出現3級的周胎情況,說明胎盤正在老化 ,盘成有可能會造成胎兒缺氧的熟度情況 。31周胎盤成熟度2級其實也是周胎正常的,不用過於擔心 。盘成

我們都知道 ,熟度胎盤的周胎每個級別對應不同孕周,一般情況下,盘成孕28周之前都屬於0級 ,熟度這時候胎盤還未成熟,周胎吸收能力比較弱;孕29到36周屬於1級,盘成這時候胎盤基本成熟 ,熟度吸收能力是四個級別中最好的;孕37到40周屬於2級,這時候胎盤比較成熟,吸收能力開始下降 ,但是還能給胎兒提供足夠的營養成分和氧氣;孕40周以上屬於3級 ,這時候胎盤已經成熟,並開始老化 ,吸收能力已經沒有了,而且3級的胎盤已經無法給胎兒提供營養和氧氣,胎兒隨時都會有缺氧的可能 。

正常來說,孕31周的胎盤成熟度應該是1級的 ,當然了,如果孕婦在孕期補鈣過量了 ,那麽也可能會導致胎盤提前早熟。也就是說,孕31周的胎盤2級也是正常的,孕婦先不要擔心 ,隻要保持胎盤的成熟度不再升級 ,就不用擔心胎兒會提前出來。至於怎麽保持胎盤的成熟度 ,這個可以到醫院谘詢醫生 ,醫生會給到你有用的建議。

一般來說 ,胎兒在孕37周以上就已經算是足月的胎兒了 ,這時候的胎兒隨時都有可能會分娩出來。而在孕28到36周之間分娩出來的胎兒才算是早產兒 ,通常情況下,早產兒都是由於外在因素導致胎兒動了胎氣 ,從而提前分娩出來的,而胎盤是屬於內在因素。也就是說,如果胎盤真的在胎兒還沒足月就已經到達3級,那麽為了胎兒以及孕婦的安全起見,就算剖腹產也要把胎兒取出來 。
所以說831周胎盤2級會早產嗎?答案是不一定的,雖然說胎盤2級的吸收能力沒有1級的強,但是胎盤2級也不會對胎兒造成影響,隻要胎盤繼續保持這個成熟度,直到胎兒足月並分娩出來就可以了。當然 ,如果胎盤在胎兒未足月之前就已經無法保持胎盤2級成熟度,那麽為了避免胎兒出現缺氧問題,就算剖腹產也要把胎兒取出來。
