1、頜面部CT增強掃描造影劑外滲的預防及護理方偉華孫琦(通訊作者)董敏俊陶曉峰(上海交通大學醫(yī)學院附屬第九人民醫(yī)院放射科上海200011)【摘要】目的:探討頜面部CT增強掃描造影劑外滲的預防及發(fā)牛外滲后的正確護理方法。方法:72例頜面部CT增強掃描造影劑外滲病人的臨床資料,回顧性分析CT增強造影劑外滲的處理及預后。結果:72例頜面部CT增強滲出患者中,按掃描類別分,CTA掃描滲出例數(shù)占58.33%,常規(guī)增強占29.17%,功能成像增強占12.5%;按造影劑類別分,分別應用4種造影劑滲出患者無統(tǒng)計學差異(P>0.05)o按CT造影劑注射速率分
2、,速率為4.0?5.0mI的占54.17%,速率為2.0?3.0ml的占19.44%,速率為3.0?4.0ml的占26.39%;按造影劑劑量分,注射劑量70?100ml的滲出例數(shù)大于劑量≤70ml的例數(shù);按滲出面積分,輕度造影劑外滲(造影劑滲出小于10ml)的占77.78%,中度造影劑外滲的占16.67%,重度造影劑外滲的為5.56%;按腫脹范圍分,腫脹范圍1?3cnn的占75%,4?10cm的占19.45%,超過:LOcm的占5.56%。經(jīng)積極處理及針對性護理,經(jīng)隨訪證實均未出現(xiàn)后遺癥。結論:CT增強掃描造影劑外滲的原因是多方面的,采
3、取積極的預防措施是減少或避免造影劑外滲發(fā)牛的重要方法,關鍵是有針對性的及時護理。【關鍵詞】頜面部;外滲;CT增強;造影劑;護理【中圖分類號】R472【文獻標識碼】B【文章編號】2095-1752(2016)05-0237-03ThepreventionandnursingofCTenhaneedcontrastagentextravasationinMaxillofacial.FangWei-hua,SunQi,DongMin-junjaoXiao-feng.DepartmentofRadiology,ShanghaiNinthPeople&
