深静脉穿刺置管是建立安全、快速、有效静脉通路的重要方法。颈内静脉因其解剖位置较为固定,容易穿刺,可快速补液,防止高渗药物对外周血管壁的刺激,血管并发症少,可监测中心静脉压,活动不受限制、留置时间长,被临床作为血管通道在临床广泛使用。国内文献报道,中心静脉脱管发生率为3.80%~13.67%~([1-4]),维持有效固定,防止非计划脱管发生是护理质量的重要指标之一。因此,为了防止静脉导管脱管,减 Deep venous catheterization is an important way to establish safe, rapid and effective intravenous access. The internal jugular vein because of its anatomical location is more fixed, easy to puncture, rapid rehydration, to prevent hyperosmolar drugs on the peripheral vascular wall stimulation, less vascular complications, monitoring of central venous pressure, activities are not limited to stay for a long time, was clinical As a vascular access widely used in clinical. Domestic literature, the incidence of central venous detachment was 3.80% ~ 13.67% ~ ([1-4]), to maintain an effective fixed to prevent unplanned derailment is an important indicator of quality of care. Therefore, in order to prevent venous catheter detuning, minus
