中心静脉穿刺新进针点的可行性研究

Objective To evaluate the feasibility of a new approach to internal jugular vein (IJV) catheterization. Methods Sixty patients undergoing cardiac surgery were randomly divided into two groups (n=30). In group Ⅰ, a new method was used. In group Ⅱ, IJV catheterization from a high medial approach. The overall succcess rate of puncture, the success rate of puncture at first attempt, the success rate of cannulation and complication were recorded. Chest X-ray was taken for confirmation of the position of catheter in subclavian vein. Results The overall success rate of puncture was 100% and the success rate of puncture at first attempt was 93.33% in group Ⅰ, which is significantly higher than those in group Ⅱ(P<0.05). No complication occurred in group Ⅰ including arterial puncture, pneumothorax, hematothorax and difficult catheter placement. In group II there were 3 arterial punctures. Con-clusion This new method is a reliable and safe technique in patienst as compared with the high medial approach.
