两种桡动脉采血方法的对比研究

Two kind of radial arteries pick the blood method the contrast research

目的：提高桡动脉穿刺一次成功率，降低血标本凝血发生率，减轻患者痛苦。方法：600例患者随机分为A、B两组，A组采用1ml注射器进行动脉穿刺采血，B组采用2ml注射器连接7号头皮针进行动脉穿刺采血。观察并比较两组桡动脉穿刺采血一次穿刺成功率、标本凝血发生率及患者疼痛程度。结果：A组一次性穿刺成功率明显高于B组（P值〈0．01），A组凝血发生率低于B纽（P值〈0．01），A组患者疼痛程度低于B组（P值〈0．01）。结论：采用1ml注射器进行动脉穿刺相比2ml注射器连接7号头皮针进行动脉采血，能减轻患者的疼痛，降低血标本凝血发生率，提高穿刺率降低，且价格相对便宜，是桡动脉穿刺理想的穿刺方法，值得推广。

Objective：Improve the success rate of gathering blood from the radial artery,to reduce the incidence of coagulation, and reduce the pain of patients. Methods： 600 patients accepting puncturing for blood sample collection from radial artery were ran- domly divided into A and B group. A group used /ml injector and B group used 2ml injector connected No. 7 scalp needle. Then one time puncturing success rate,incidence of coagulation and pain scale were observed and compared. Results： The success rate of A group was much higher than that of B group（P〈0.01）. The incidence of coagulation and pain scale of A group were lower than those of B group（P〈0.01）. Conclusion：Puncturing the radial artery with lml injector was better than 2ml injector connected No. 7 scalp needle in increasing the success rate of gathering blood, reducing the incidence of coagulation and pain of patients, while it was cheaper. This method is worth to spread
