摘要
目的 探讨超声引导下PICC置入上腔静脉中下1/3处理想位置的体外测量方法,以提高导管置入长度的准确性,保证患者的安全。方法 选择2015年12月~2016年7月本院行PICC置管患者200例,随机分为对照组和实验组,每组各100例,对照组采用常规的“横L法”即从穿刺点至右胸锁关节再向下返折至第三肋间;实验组采用从穿刺点至右胸锁关节的长度加上根据身高确定的长度的数值,就是置入的长度,置管成功后予以胸片定位。结果 比较两组患者PICC置入长度的准确性,实验组PICC置入的准确性高于对照组（P〈0.05）。结论 PICC置管的测量方法,采用改良后的技术即从穿刺点至右胸锁关节再加上根据身高确定的增加数值即为置入长度,提高了导管置入上腔静脉中下1/3理想位置的准确性,减少了并发症,保证患者的安全。
Objective To study the ultrasound guided b PICC placement superior vena cava lower 1/3 processing to the location of the measurement method in vitro, in order to improve the accuracy of the length of catheterization, ensure the safety of patients. Methods 200 cases of patients with PICC line were chsoen from December 2015 to July 2016 in our hospital, were randomly divided into control group and experimental group, 100 cases in each group, control group using conventional ＂cross L method＂ that is, from the puncture point to right sternoclavicular joints again returned to the fold down to the third floor. Used to fight the length of the stemoclavicular joints from the puncture point and according to determine the value of the length of the height, is the length of the placement, after the success to the X-ray tube. Results To compare the two groups of patients with PICC placement accuracy, the length of the experimental group of PICC placement accuracy is significantly higher than control group （P〈0.05）. Conclusion The measurement method of PICC catheter, with modified technique namely from the puncture point to right stemoclavieular joint plus according to height increase value is in length, improve the superior vena cava lower 1/3 catheterization ideal location accuracy, reduce the complications and guarantee the safety of the patients.
