Patency of the vascular access device and the vein that houses the device is critical for the successful delivery of infusion therapy. Loss of catheter patency comes from decisions made during device insertion and from methods used for infusion, flushing, dressing, and removal. Loss of vein patency comes from insertion techniques, patient activity, anatomic and physiologic reasons, and the primary disease or underlying chronic diseases. This review provides the latest information on causes, reported incidences, management, and prevention of catheter and vein patency problems frequently encountered in all clinical settings.
血管通路装置及其所在静脉的通畅对于成功实施输液治疗至关重要。导管通畅性的丧失源于装置插入过程中所做的决策以及输液、冲管、换药和拔除所采用的方法。静脉通畅性的丧失源于插入技术、患者活动、解剖和生理原因以及原发性疾病或基础慢性病。本综述提供了有关在所有临床环境中经常遇到的导管和静脉通畅问题的原因、报告的发生率、管理和预防的最新信息。
