1、臨床醫(yī)學(xué)論文?肝素治療胎兒生長受限臨床應(yīng)用探討【摘要】目的:探討肝素用于治療胎兒生長受限(FGR)的臨床療效及安全性。方法:將74例胎兒生長受限患者隨機分為3組,分別使用低分子右旋糖肝加復(fù)方丹參(對照組)、普通肝素(UFH)、低分子肝素(LMWH)治療。治療前、治療后1周及終止妊娠前,行彩色超聲檢查,監(jiān)測胎兒生長情況和臍血流變化侗時監(jiān)測各項凝血指標(biāo),記錄新生兒情況并進行隨訪。結(jié)果:(l)UFH組、LMWH組治療后宮高、胎兒股骨長、頭圍、腹圍增長値均高于對照組,差異有顯著性(P<0?05),LMWH組胎兒雙頂徑增長顯著高于對
2、照組(P二0.031)。(2)兩肝素組治療后臍動脈收縮期最大血流速度(S)與舒張末期血流速度(D)的比値(S/D比値)、搏動抬數(shù)(PI)、阻力指數(shù)(RI)與對照組比較均明顯降低,差異有統(tǒng)計學(xué)意義(P<0?05),而兩肝素組間比較無統(tǒng)計學(xué)差異(P>0.05)。(3)UFH組、LMWH組治療后新生兒胎齡、出生體重、身長、胎盤重量均較對照組明顯增加(P<0?05),而兩肝素組問無顯著差異(P>0?05);新生兒窒息、胎死宮內(nèi)、新生兒死亡發(fā)生率、早產(chǎn)發(fā)生率和新生兒畸形發(fā)生情況各組間無統(tǒng)計學(xué)差異(P>0.05);對照組足月小樣兒發(fā)生
3、率明顯高于兩肝索組(P二0.005),而肝素組之間則無顯著差異(P>0?05)。對照組與LMWH相比,新生兒轉(zhuǎn)重癥監(jiān)護病房(NICU)幾率明顯升高(P二0.003)。(4)各組孕婦治療前后各項凝血功能檢測値比較,差異均無顯著性(P>0.05),產(chǎn)后出血量及產(chǎn)后出血發(fā)生率相比差異亦無統(tǒng)計學(xué)意義。結(jié)論:肝素可改善胎盤血流,使胎兒體重增加,減少足月小樣兒的發(fā)生率,且不增加產(chǎn)后出血發(fā)生機會,對母親及胎兒都較安全。LWMH治療FGR,新生兒轉(zhuǎn)NICU幾率明顯低于對照組,效果優(yōu)于普通肝素,且使用方便,產(chǎn)婦易于接受,更適于推廣?!娟P(guān)鍵詞
