摘要
Objective:To systematic evaluation by the dorsalis pedis artery puncture for bed patients blood gas analysis of application effect of impact.Methods:A randomized controlled trial of the effect of arterial blood extraction on blood gas analysis in PubMed,CNKI,Wanfang database and VIP database.After selecting the literature,extracting the data and evaluating the quality of the literature.Meta- analysis was carried out by RevMan 5.3 software.Results:Twelve randomized controlled trials were included and 1696 patients were enrolled.After meta-analysis,the arterial puncture can effectively improve the success of arterial puncture in patients with bed [Z = 5.78,95%CI(1.90,3.66),P<0.001],reduce the occurrence of hematoma [Z = 4.27,95%CI(0.19,0.54),P<0.001],reduce the mistaken into the vein [Z = 4.60,95%CI(0.08,0.36),P<0.001],reduce cyanosis [Z = 2.84,95%CI(0.23,0.81),P<0.008],the difference was statistically significant.Conclusion:Dorsalis pedis artery puncture can improve the success rate of blood gas analysis in bedridden patients,reduce the incidence of hematoma and the incidence of venous leakage,and can be widely used in clinical practice.
目的:系统评价经足背动脉采血在卧床患者血气分析中的应用效果。方法:检索PubMed、中国知网、万方数据库及维普数据库中关于经足背动脉采血在血气分析中的应用效果的随机对照试验(RCTs)。2名评价者独立对文献进行检索及筛选、提取相关数据,并对纳入文献的方法学质量进行评价后,采用RevMan5.3软件行Meta分析。结果:最终纳入12项随机对照试验,共计1696例患者。经Meta分析,经足背动脉穿刺使卧床患者动脉穿刺一次成功情况提高[Z=5.78,95%CI(1.90,3.66),P<0.001],减少血肿发生[Z=4.27,95%CI(0.19,0.54),P<0.001],减少误穿静脉的发生[Z=4.60,95%CI(0.08,0.36),P<0.001],减少青紫发生[Z=2.84,95%CI(0.23,0.81),P<0.008]差异均有统计学意义。结论:足背动脉穿刺可以提高对卧床患者动脉穿刺时一次成功的情况,减少血肿、误穿静脉及青紫的发生,可在临床推广。
