新生儿桡动脉采血与股静脉采血的成功率与副作用的差异研究

Research of difference of success rate and side effects of neonatal radial artery blood sampling and femoral vein blood collection

目的 比较新生儿桡动脉采血与股静脉采血的成功率与副作用.方法 选取2016年1月至2017年2月来我院行血液生化检查的新生儿248例,按随机数字表法分为两组,对照组124例新生儿,采取股静脉采血的方式,观察组124例新生儿,采取桡动脉采血的方式,比较两组一次性采血成功率、采血时间及不良事件发生情况.结果 观察组采血时间为（3.82±0.51）min,对照组采血时间为（6.82±1.16）min,差异有统计学意义（t=5.1734,P＜0.05）.观察组新生儿一次性穿刺成功率为97.58%,明显高于对照组的80.65%,且观察组新生儿的不良事件总发生率为6.45%,明显低于对照组的18.55%,差异具有统计学意义（P＜0.05）.结论 在新生儿血液生化检查中,采取桡动脉采血的方式,有利于提高穿刺成功率,缩短采血时间,同时可降低不良事件发生率.

Objective To compare the success rate and side effects of neonatal radial artery blood sampling and femoral vein blood collection. Methods Two hundred and forty-eight cases of newborns who underwent the blood biochemical exami- nation in our hospital from January 2016 to February 2017 were selected, and divided into two groups according to random number table method. The 124 cases newborns of control group were taken the way of femoral vein blood collection, while the 124 cases of newborns of observation group were taken the radial artery blood collection. Then the success rate, the time of blood collection and the incidence of adverse events were compared between the two groups. Results The time of blood collection in the observation group was （3.82±0.51） min, while in the control group was （6.82±1.16） min, the difference was statistically significant （t=5.1734, P〈0.05）. The success rate of one-time puncture in the observation group was 97.58%, which was higher than 80.65% of the control group; the adverse events incidence rate of the observation group was 6.45%, which was lower than 18.55% of the control group, the differcences were statistically significance （P〈0.05）. Conclusion In neonatal blood biochemical examination, the method of radial artery blood sampling is helpful to improve the successful rate of punc- ture, shorten the time of blood sampling and reduce the incidence of adverse events, which is worthy of clinical application.
