随着内镜技术的不断发展,各种镜下微创手术已不断成熟,尤其是经内镜在数字减影血管成像机(DSA)下进行的各种微创手术,如:胆总管取石术,食道、胆道、肠道、胰管等支架的置入术。术中护士除全程受到射线辐射外,还接触被携带各种病原菌患者污染的器械及分泌物,其中包括乙型肝炎、梅毒、艾滋病患者等。因此,逆行胰胆管造影 With the continuous development of endoscopic techniques, a variety of microscopic minimally invasive surgeries have matured, especially various minimally invasive surgeries performed under endoscopic digital subtraction angiography (DSA), such as choledocholithiasis , Esophagus, biliary tract, intestine, pancreatic duct and other stent placement. Intraoperative nurses in addition to the whole course of radiation exposure, but also to be exposed to carry a variety of pathogens contaminated devices and secretions of patients, including hepatitis B, syphilis, AIDS patients.
