　　導(dǎo)致臍帶扭曲的真正原因，目前醫(yī)學(xué)上還沒有明確認(rèn)定，有些學(xué)者認(rèn)為是可能與臍帶發(fā)育不良，局部華通氏膠薄弱有關(guān)，華通氏膠薄弱，臍血管順縱軸扭曲，血管隨之扭曲變窄，使臍血流受阻，極易引起胎兒宮內(nèi)窘迫及猝死。另有學(xué)者認(rèn)為臍帶扭曲與孕產(chǎn)情況和胎兒性別有關(guān)，認(rèn)為經(jīng)產(chǎn)婦腹壁松弛，便于胎兒活動，男胎活動度大，易發(fā)生扭曲。還有一些學(xué)者主張是胎兒死亡后才產(chǎn)生扭曲現(xiàn)象。</p><p> 　　臍帶扭曲屬于一種子宮內(nèi)的突發(fā)狀況，到目前為止醫(yī)學(xué)上仍然無法提早偵測出征兆，不過可以通過加強圍產(chǎn)期的監(jiān)測，發(fā)現(xiàn)臍帶血流變化異常，及早挽救胎兒生命。</p><p><strong>　　臍帶扭曲的危害</strong></p><p> 　　過分扭曲的臍帶多在近胎兒臍輪部變細(xì)壞死，引起血管閉塞，胎兒因血運中斷而死亡。</p><p><strong>　　如何預(yù)防臍帶扭曲</strong></p><p> 　　1、數(shù)胎動：懷孕28周起，就要注意胎動變化，每日早晨、中午、晚上在左側(cè)臥位的情況下，各測一小時胎動。一旦發(fā)現(xiàn)胎動次數(shù)低于正常，應(yīng)及時檢查，挽救胎兒。</p><p> 　　2、買個胎心監(jiān)護(hù)儀：可以的話，買一個胎心監(jiān)護(hù)儀，一般200元左右，可以每天在家聽胎心監(jiān)護(hù)，做到及早發(fā)現(xiàn)孩子在肚子里的情況。</p><p> 　　3、左側(cè)睡覺：左側(cè)臥位可以減輕增大的妊娠子宮對孕婦主動脈的壓迫，可以維持正常子宮動脈的血流量。</p><p> 　　4、吸氧：如果臍血流值高的話，可以試試到附近的醫(yī)院吸氧，每天吸氧1小時，可以緩解胸悶情況，對胎兒缺氧也有一定的改善。</p><p> 　　5、不要久坐：長時間坐著工作，活動少，影響血液循環(huán)，骨盆受壓迫使子宮血液循環(huán)不暢，讓母體受到傷害而影響寶寶健康。</p> </div> <div id="g8hw4jw" class="y_ju"></div> <div
