ABSTRACT
Objective The incidence rate of complication during central venous catheterization through internal jugular vein (IJV) and subclavian vein (SV) puncture. Methods Clinical controlled trials about IJV and SV puncture were collected and related literatures were screened according to the criteria of inclusion. The literatures underwent Meta analysis and subsequent analysis of sensitivity. Results A total of 18 literatures were included. Meta analysis indicated that statistical difference existed in the related infection rate [RR=1.74, 95%CI (1.32, 2.30)] and arterial puncture [RR=3.19, 95%CI (1.70, 5.99)], but not in the one-time-puncture success rate [RR=1.06, 95%CI (0.90, 1.24)] between IJV and SV puncture. Conclusions The rate of related infection and arterial puncture was higher by IJV than by SV puncture. But we could not confirm if any difference existed in the one-time-puncture success rate between the two methods. The results still needs evaluation by high-quality randomly controlled experiments.
