Clinical observation of Zhang point in the subclavian vein puncture / 中国医师进修杂志

ABSTRACT

Objective To observe the clinical effect of Zhang point in subclavian vein puncture. Methods One hundred patients underwent deep vein catheterization were selected, ASA grade of Ⅱ- Ⅲ. The patients were divided into 2 groups according to puncture method with 50 cases each, the patients in group A used traditional puncturing method, and the patients in group B used Zhang point puncture method. The total success rate, success rate of the first trial and incidence of complication were recorded. All the patients received the bedside chest X-ray examination to observe the location of central venous catheter after surgery. Results The total success rate and success rate of the first trial in group B were significantly higher than those in group A100%(50/50) vs. 88%(44/50) and 96%(48/50) vs. 76%(38/50), the incidence of complication was significantly lower than that in group A 4% (2/50) vs. 20%(10/50), there were statistical differences (P<0.05). Conclusions Using of Zhang point is very simple in subclavian vein puncture catheterization, with a higher success rate and a less complication rate.
