体重百分数对颈外静脉置入PICC准确性的影响研究

Influence of Weight Percentage on the Accuracy of PICC via External Jugular Vein

目的探讨体重百分数对颈外静脉置入PICC体外长度测量准确性的影响.方法 102例经颈外静脉置入PICC的患者随机分为对照组和观察组各51例,测量2组患者身高、体重,计算实测体重占标准体重的百分数.对照组患者采用常规方法获取PICC的置管长度,观察组患者根据不同体重百分数采用改良PICC置管长度测量法,比较2组PICC导管置入上腔静脉的成功率、体重百分数对体表测量长度的影响及与实际置入长度的偏差.结果观察组PICC管置入上腔静脉的中下段的例数比对照组高,2组置管成功率比较,差异有统计学意义(P<0.01).结论颈外静脉置入PICC根据患者体重百分数分别采用不同测量方法,使导管长度更准确,操作更为安全.

Objective To evaluate the influence of weight percentage on the measuring length accuracy of PICC via external jugular vein.Methods 102 patients who received PICC catheter via external jugular vein were randomly divided into 2 groups： control group and observation group,with 51 in each group. Firstly,their height and weight were respectively measured,and then the standard weight of patients and the percentages between actual and standard weight were calculated. The traditional method was used to get the PICC tube length for control group.Weight percentage of patients in the observation group was calculated with the improved method. Then we compared the difference in PICC catheters＇ success rate,the deviation between weight percentage＇ influence on the length of body surface measurement, and actual insertion length between two groups.Results The number of PICC tube implanted in the mid and inferior segment of the superior vena cava in the observational group was more than the control group. The success rate of catheterization in the observational group was higher than the control group（P0.01）.Conclusion Different measurement method should be adopted for different patients according to weight percentage after PICC via external jugular vein, which may make the pipe length more accurate and operation safer.
