颈外静脉PICC置管患者导管异位发生现状分析

Status quo of incidence of PICC misplacement in external jugular vein

目的：分析颈外静脉行PICC置管患者导管异位发生现状。方法选取2014年8月至2015年5月在吉林省某三甲医院肿瘤科行颈外静脉置管的患者97例作为研究对象，比较患者原发性导管异位与继发性导管异位的发生率，并将患者按穿刺部位分为左、右颈外静脉组，比较两组患者的导管异位发生率。结果97例颈外静脉置管患者，发生异位20例，发生率为20.6%，其中原发性导管异位17例、继发性导管异位3例；右颈外静脉置管发生导管异位12例，左颈外静脉置管发生异位8例，两组比较差异无统计学意义（ P〉0.05）。结论原发性导管异位发生率高于继发性导管异位发生率，故置管时更应注意预防原发性导管异位的发生；在本研究中，左、右颈外静脉置管发生异位率无明显区别，左、右侧颈外静脉对导管异位发生率可能无重要影响。

Objective To investigate the status quo of incidence of PICC misplacement in external jugular vein. Methods A total of 97 cases patients who received PICC in the Oncology Department of a third-level grade-A hos-pital in Jilin province from August 2014 to May 2014 were selected as the research objects. The incidences of primary and secondary catheter misplacement were compared. The patients were divided into left and right external jugular vein groups and the incidence of catheter misplacement of them were compared. Results Among the 97 cases of patients with PICC, 20 cases had misplacement, with the incidence of 20. 6%, including 17 cases of primary catheter misplacement and 3 cases of secondary catheter misplacement. There were 12 cases and 8 cases of catheter misplacement among the right and left external jugular vein groups respectively. Conclusions The incidence of primary catheter misplacement was higher than that of secondary catheter misplacement, so more attention should be paid to preventing the incidence of primary catheter misplacement in the process of PICC. In this study, there were no significant differences between the incidences of left and right external jugular vein catheter, showing they might have no significant influence on the inci-dence of catheter misplacement.
