中心静脉穿刺新进针点的可行性研究

目的 通过对一种新的颈内静脉置管与高位前路颈内静脉置管进行比较,评价其可行性.方法 选择心脏手术病人60例,随机分为2组,每组30例,Ⅰ组一种新的途径行颈内静脉置管,Ⅱ组高位前路颈内静脉穿刺置管.观察记录总穿刺成功率、一次试穿成功率、置管成功率及并发症.观察中心静脉导管位置,并均于术后x线摄胸部平片.结果 Ⅰ组穿刺总成功率100%,一次穿刺成功率93.33%,均显著高于Ⅱ组(93.33%和60.00%)(P<0.01),Ⅰ组患者无误穿动脉、气胸、血胸及导管异位等并发症发生.结论 该新的穿刺方法具有操作容易、安全性大、穿刺置管成功率及一次穿刺成功率高等特点,是经皮中心静脉置管有实用价值的方法之一.

The clinical study of catheterization of internal jugularvein (IJV) from the new point

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.
