多普勒超声腔内心电一体化引导建立和维护中心血管通路专家共识

Expert consensus on the establishment and maintenance of central vascular access under electrocardiographyDoppler ultrasound guidance

中心血管通路装置是治疗临床重症、肿瘤、长期需要进行静脉输液患者的重要工具。选择适当的穿刺部位和血管,确保正确的导管头端位置,对维护其长期通畅率,降低感染、血栓形成、导管异位等并发症的发生率至关重要。应用多普勒超声行血管评估与穿刺,结合腔内心电定位导管头端位置,替代传统盲目穿刺及置管术后X线定位,可避免孕妇、新生儿及儿童等患者射线暴露损伤。将多普勒超声与腔内心电定位技术有机结合的一体化设备称为多普勒超声腔内心电一体化引导(EDUG),现已广泛应用于临床,成为辅助临床微创手术、介入治疗、急诊抢救和临床护理操作的新方法。中国医学装备协会心血管装备技术专业委员会联合中国介入医学产业技术创新联盟经皮血管通路创新中心、中国医师协会介入医师分会介入医学工程与生物技术专业委员会有关专家,结合临床实践形成专家共识,为医护人员提供参考。

Central vascular access is an important tool for patients with clinically severe condition,tumor,and long-term need for intravenous infusion.The placement and indwelling of vascular access in the appropriate vessels and the correct position of the catheter tip can maintain long-term patency and reduce complications such as infection,thrombosis and catheter displacement,etc.The application of ultrasound Doppler combined with electrocardiography to guide the operation and maintenance of vascular access,instead of the traditional blind venipuncture and chest X-ray post-procedural location,is able to avoid radiation exposure damage to patients,especially pregnant women,newborns and children.The device of ultrasound Doppler combined with electrocardiography is called electrocardiography Doppler ultrasound guiding(EDUG),which has been widely used in clinical practice and accepted a new method of minimally invasive surgery,interventional treatment,emergency rescue and nursing clinical operation of vascular access in China.The experts from Cardiovascular Equipment Technical Committee of China Medical Equipment Association,China Interventional Medical Industry Technology Innovation Alliance Percutaneous Vascular Access Innovation Center,Interventional Medical Engineering and Biotechnology Committee on Interventional Physician of Chinese Medical Association discussed the expert consensus together,combined with the clinical practice and scientific questions,which would be a reference for clinical physicians and nurses.
