血管內(nèi)介入的基礎(chǔ)知識(shí)

1、術(shù)前準(zhǔn)備,患者常規(guī)備皮過敏試驗(yàn)（碘）左側(cè)肢體建立輸液通道各種監(jiān)護(hù)裝配留置導(dǎo)尿,導(dǎo)管室內(nèi)所需物品,心電、呼吸監(jiān)護(hù)設(shè)備氧氣供給系統(tǒng)各類急救藥品及設(shè)備鎮(zhèn)靜藥、解痙藥、肝素、魚精蛋白及尿激酶等,血管造影所需器械,穿刺針（套管針）血管擴(kuò)張器（血管鞘）Y 閥（二相、三相）三通高壓輸液袋延長(zhǎng)管導(dǎo)絲（.032-.035) （泥鰍導(dǎo)絲，交換導(dǎo)絲）造影導(dǎo)管,Procedure - Seldinger Technique (1)

2、步驟-Seldinger 技術(shù),The skin is prepared and punctured穿刺部位備皮The femoral artery and inguinal ligament are located 股動(dòng)脈位于腹股溝韌帶處The needle with stylet is angled parallel to the course of the femoral artery 套管針的針頭傾斜平行進(jìn)入到股

3、動(dòng)脈內(nèi),Procedure - Seldinger Technique (2)步驟,Artery is punctured (double or single wall technique) 穿刺動(dòng)脈Stylet is removed and needle withdrawn until blood flow occurs移動(dòng)套管針將針頭回撤直到看到回血Cannula removed 移動(dòng)套管Wire inserted 導(dǎo)絲插入
