新生儿采用足背动脉定位采血法的可行性研究

Feasibility study on positioning blood sampling through dorsal artery for newborns

目的探讨足背动脉定位采血法的可行性,为新生儿动脉采血提供更多方法及部位选择。方法将120例需动脉采血的新生儿采用摸球法随机分成对照组和观察组各60例。观察组采用足背动脉定位采血,对照组采用桡动脉定位采血,比较两组一次性穿刺成功率、采血针充盈时长、采血后按压时间、标本溶血以及血肿发生情况。结果两组新生儿一次性穿刺成功率及标本溶血率差异无统计学意义(P>0.05),观察组采血针充盈时长、采血后加压止血时间及血肿发生率低于对照组,比较差异有统计学意义(P<0.05)。结论新生儿动脉采血可选用足背动脉定位法。

Objective To study the feasibility of positioning blood sampling through dorsal artery to provide evidence for more methods and positions of arterial blood sampling for newborns.Method Divide 120 newborns who need blood sampling into observation group（n=60）and control group（n=60）by catching balls randomly.Collect blood through dorsal artery in observation group and through radial artery in control group.Compare the one-time success rate of puncture,filling time of sample collection needles,compressing time after blood collection,sample hemolysis and hematoma between two groups.Result There is no significant difference on one-time success rate of puncture and sample hemolysis between two groups（P〉0.05）.Filling time of sample collection needles,compressing time after blood collection and incidence of hematoma is lower in observation group than in control group.The difference is significant（P〈0.05）.Conclusion Artery blood sampling for newborns can through dorsal artery positioning.
