2、定動(dòng)脈血?dú)狻⒎胃桑瘽裰乇?、支氣管肺泡灌洗液總蛋白含量和凝血功能。結(jié)果:與正常對(duì)照組相比,生理鹽水霧化組和低分子肝素霧化治療組動(dòng)脈血氧合指數(shù)、肺干/濕重比值顯著降低(P<0.05),支氣管肺泡灌洗液總蛋白含量顯著升高(P<0.05),而低分子肝素霧化治療組較生理鹽水霧化組動(dòng)脈血氧合指數(shù)、肺干/濕重比值顯著升高(P<0.05),支氣管肺泡灌洗液總蛋白含量顯著降低(P<0.05);凝血酶原時(shí)間以及活化部分凝血活酶時(shí)間生理鹽水霧化組和低分子肝素霧化治療組間沒(méi)有顯著差異(P>0.05),但均較正常對(duì)照組延長(zhǎng)(P<0.05)。結(jié)論:低分子肝素霧化吸入治療可以改善肺換氣,提高氧合,
3、降低肺泡滲出,并且對(duì)凝血功能沒(méi)有明顯的副作用,可以在一定程度上緩解急性肺損傷。本研究為急性肺損傷的治療提供了新的思路和實(shí)驗(yàn)依據(jù)。關(guān)鍵詞:低分子肝素;霧化治療;急性肺損傷中圖分類(lèi)號(hào):R563;R965文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1673-6273(2014)15-2867.04TherapeuticEffectsofLowMolecularWeightHeparinNebulizationonAcuteLungInjuryXIENian—lin,CAOXiang~,YANSi-jun,DENGBo-rong,XUShao-gan(DepartmentofThoracocar
