CONTEXT
Blind insertion of central venous catheter has many implications. Better options should be sought to perform this procedure.
AIM
To evaluate various options for positioning central venous catheter tip.
SETTINGS AND DESIGN
This is institutional based randomized prospective controlled study.
MATERIALS AND METHODS
In this prospective study depth and position of central venous catheter were evaluated in 150 patients in intensive care unit. Three different methods: Pere's, landmark, and endocavitory (atrial) ECG control were used.
STATISTICAL ANALYSIS
Twoway ANOVA test was applied on SPSS version 16 to test the significant difference between the three groups.
RESULTS
Patient characteristic and demographic data were similar in the three groups. The average depth of central venous catheter by Pere's, landmark, and endocavitory (ECG) technique were 14.20 ± 0.69 cm, 12.08 ± 0.98 cm, and 8.18 ± 0.74 cm, respectively.
CONCLUSION
The correct position of central venous catheter by endocavitory (atrial) ECG appears not only to reduce the procedure related complications but also post procedure manipulation of catheter tip detected by post procedure chest X-ray.
背景
中心静脉导管的盲目插入有诸多影响。应寻求更好的方法来进行该操作。
目的
评估中心静脉导管尖端定位的各种方法。
设置与设计
这是一项基于机构的随机前瞻性对照研究。
材料与方法
在这项前瞻性研究中，对重症监护病房的150例患者的中心静脉导管的深度和位置进行了评估。使用了三种不同的方法：佩雷氏法、体表标志法和心腔内（心房）心电图控制法。
统计分析
在SPSS 16版本上应用双向方差分析来检验三组之间的显著差异。
结果
三组患者的特征和人口统计学数据相似。佩雷氏法、体表标志法和心腔内（心电图）技术放置中心静脉导管的平均深度分别为14.20±0.69厘米、12.08±0.98厘米和8.18±0.74厘米。
结论
通过心腔内（心房）心电图确定中心静脉导管的正确位置，似乎不仅能减少与操作相关的并发症，还能减少术后胸部X线检查发现的导管尖端的术后调整。
