摘要 目的探讨正确的PICC尖端位置,确保导管功能和患者安全。方法以气管隆突为标识的导管尖端"中心静脉"定位,包括上腔静脉和卡沃-心房交接处两部分。上腔静脉和卡沃-心房交接处在标准后前位胸片上,界定为气管隆突之上3cm和气管隆突之下5cm的区域。导管尖端位于这一区域内判定为"中心静脉",导管尖端未在这一区域内判定为"非中心静脉"。置管护士和放射科主治医师同时、独立评价所有导管尖端,两人评价不一致的导管尖端,由放射科副主任医师进行第三方评价,并以第三方评价结果为准。导管尖端定位情况采用百分率描述。结果位于中心静脉的导管占76.8%(229例),位于非中心静脉的导管占23.2%(69例)。异位部位由高到低分别为:无名静脉23例,颈内静脉21例,右房16例,锁骨下静脉5例,腋静脉4例。结论以气管隆突为评价标识的导管尖端评价结果显示,床旁盲穿PICC中心静脉定位率不甚满意。建议开展设计严谨的导管异位影响因素及预防干预方面的研究,尽量提高导管中心静脉定位率。
