1、CT增強(qiáng)掃描造影劑滲漏的預(yù)防及護(hù)理分析薛永春(四川省中江縣人民醫(yī)院四川德陽(yáng)618100)【摘要】CT是利用精確準(zhǔn)直的X線朿、γ射線、超聲波等,與靈敏度極高的探測(cè)器同圍繞人體的某一部位作一個(gè)接一個(gè)的斷面掃描,具有掃描時(shí)間快,圖像清晰等特點(diǎn),目前被應(yīng)用于多種疾病的檢查中。CT增強(qiáng)掃描就是在血管內(nèi)注入對(duì)比劑而進(jìn)行的掃描技術(shù),主要是經(jīng)靜脈快速注入含碘造影劑,使血中含碘量維持一定水平,增強(qiáng)器官和病灶的影像效果;可以發(fā)現(xiàn)平掃未發(fā)現(xiàn)的病灶,主要用于鑒別病變?yōu)檠苄曰蚍茄苄裕鞔_縱膈病變與心臟大血管的
2、關(guān)系,了解病變的血供情況以幫助鑒別良、惡性病變等;增加病灶的信息量,以便于對(duì)病灶定性分析甚至明確診斷。造影劑屬于藥物的一種,主要用于介入放射學(xué)操作中,用來(lái)顯示血管、體腔的內(nèi)部結(jié)構(gòu)或狀態(tài)。造影劑種類多樣,目前含碘制劑較為多用。造影劑滲漏可引起局部組織水腫、疼痛等癥狀,嚴(yán)重降低了CT增強(qiáng)掃描的成功率及效果。為此木研究中分析了CT增強(qiáng)掃描造影劑滲漏的原因并探討了預(yù)防和護(hù)理方法,旨在提高CT增強(qiáng)掃描的成功率、降低造影劑滲漏的發(fā)生率?!娟P(guān)鍵詞】CT;CT增強(qiáng)掃描;造影劑滲漏【中圖分類號(hào)】R472【文獻(xiàn)標(biāo)識(shí)碼】
