以气管隆突为评价标识评价盲法PICC置管效果的研究

Effect Evaluation of Blinding Manipulation of Peripherally-inserted Central Catheter by Using the Carina as Evaluation Mark

目的以气管隆突为标识评价PICC尖端位置,为盲法PICC置管提供临床依据。方法回顾性分析2013年3月至2014年4月期间在四川大学华西医院肿瘤中心对恶性肿瘤住院患者以气管隆突为评价标识行盲法穿刺PICC置管的效果。导管尖端位置的评价采用胸部X线摄片进行。统计分析采用SPSS 19.0软件,采用频数与百分率评价置管效果。结果共评价盲法PICC置管612例,导管尖端位于中心静脉的502例,未位于中心静脉的110例。导管异位情况分别为右心房38例、颈内静脉33例、无名静脉24例、腋静脉8例、锁骨下静脉7例。结论以气管隆突为标识评价盲法PICC置管效果较好,但仍有待进一步改进。

Objective To evaluate tip location of peripherally inserted central catheter （PICC） by using the carina as evaluation mark, so as to provide clinical references for blinding manipulation of PICC. Methods A retrospective analysis about the effects of tip location of PICC by using the carina as evaluation mark on inpatients with malignant tumour was conducted in tumour centre of the West China Hospital from March 2013 to April 2014. Chest X radiography was applied to evaluate the tip location of PICC. Statistical analysis was performed using SPSS software （version 19.0） and the outcomes were presented by frequency and percentage. Results A total of 612 cases of blinding manipulation of PICC were evaluated, of which, 502 （82%） were located in the central venous and 110 （18%） were located in the noncentral venous. The numbers of those with the catheter tips located in the non-central venous were 38 in the right atrium, 33 in the internal jugular vein, 24 in the innominate vein, 8 in the axillary vein, and 7 in the subclavian vein, respectively. Conclusion The effects of blinding manipulation of peripherally-inserted central catheter by using the carina as evaluation mark are relatively good. But it still needs to be improved.
