經(jīng)驗(yàn)麻麻告訴你如何用聽(tīng)診器聽(tīng)胎心

 1819年法國(guó)內(nèi)科醫(yī)生發(fā)明了用木材制作的鐘式聽(tīng)診器，2年后開(kāi)始應(yīng)用這種木制鐘式聽(tīng)診器，直接通過(guò)孕婦的腹部聽(tīng)到了胎心搏動(dòng)的聲音，轟動(dòng)了世界。

從此以后，專(zhuān)家學(xué)者及醫(yī)生們經(jīng)過(guò)不懈的努力，完善了胎心聽(tīng)診器。20世紀(jì)初，Delee-Hillis胎心音專(zhuān)用聽(tīng)診器問(wèn)世。到了1964年，超聲多普勒效應(yīng)的應(yīng)用，讓醫(yī)生能夠更早地通過(guò)孕婦體表監(jiān)測(cè)到胎心。

健康的胎心，其搏動(dòng)聲類(lèi)似枕頭下放了一個(gè)機(jī)械小鬧表的聲音發(fā)現(xiàn)胎心音的醫(yī)學(xué)史胎兒在子宮內(nèi)有胎心音，發(fā)出類(lèi)似鐘表的“嘀嗒”聲，速度快而規(guī)律。

從孕18～20周開(kāi)始，用聽(tīng)診器可以經(jīng)孕婦腹壁聽(tīng)到胎兒心臟的搏動(dòng)音。有經(jīng)驗(yàn)的醫(yī)生，也可用普通聽(tīng)診器聽(tīng)到胎心。

胎心搏動(dòng)快慢與胎兒所處狀態(tài)關(guān)系密切(胎心的變異性)。胎兒清醒活動(dòng)時(shí)，胎心增快；胎兒處于安靜睡眠狀態(tài)時(shí)，胎心減慢。

今天在群里大家無(wú)意間聊到聽(tīng)胎心的事情，一聊才發(fā)覺(jué)好多媽媽買(mǎi)了聽(tīng)診器但是怎么也找不到胎心，到生的時(shí)候也沒(méi)用上。如果真用不上我覺(jué)得數(shù)胎動(dòng)也是很好玩滴，嘿嘿。言歸正傳。

如何用聽(tīng)診器聽(tīng)胎心?下面是我搜集的大家的小方法以及注意方式哦，歡迎大家補(bǔ)充：

1、懷孕還短得媽媽不要著急哦，那時(shí)候是很難聽(tīng)到的，最好是能等到27W+1D的時(shí)候，這樣比較容易找到。

2、相信平時(shí)媽媽們都有摸摸小寶寶的習(xí)慣，做撫摸胎教。聽(tīng)胎教的時(shí)候找到寶寶的背部（這個(gè)就能看出來(lái)你經(jīng)常摸不摸寶寶哦，嘿嘿），把聽(tīng)筒貼在胎兒背部，只要找到正確的位子，一般就可以聽(tīng)到媽媽們期待的聲音了哦。（不過(guò)寶寶背部沒(méi)貼著肚肚就難了哦）

3、聽(tīng)胎心的時(shí)候的姿勢(shì)：最好是平躺或者坐著，媽媽有所動(dòng)作，寶寶也會(huì)跟自己變換動(dòng)作哦。自己尋找一下，有時(shí)候躺著寶寶背部在下面媽媽摸不到，就坐著試試~

4、注意哦，聽(tīng)胎心的時(shí)候家里一定要安靜哦，相信大家都知道為什么哦~聽(tīng)診器的聲音其實(shí)很微弱的，所以大家要注意哦~

上面是我搜索的很多媽媽的方法，大家可以推薦一下自己的方法哦。不過(guò)醫(yī)院其實(shí)每月都有看胎心的。不著急的媽媽也可以到醫(yī)院的時(shí)候監(jiān)測(cè)哦~希望所有媽媽和寶寶們都漸漸康康滴~
