摘　　要：目的:分析动脉血气缺陷标本所占的比率、类型及其产生原因,探寻提高动脉血气分析前期质量控制的有效措施。方法:对该院2007年1月至2010年12月共314229份样本中的2594份动脉血气缺陷标本进行回顾性分析。结果:4年间血气缺陷标本占总样本数的0.83%;每年血气分析不合格标本所占比率与前一年度比较均呈下降趋势,差异有统计学意义(P<0.01)。2594份缺陷样本按原因分类,所占比率依次为:标本凝固(45.2%)、标本量少(22.3%)、气泡多(18.9%)、标识问题(10.3%)、渗入污染(3.3%)。标本凝固几乎占缺陷标本的一半,但呈逐年下降趋势,与2007年比较,2009年及2010年逐年减少(P<0.01),但标识问题、气泡多所占比率却呈上升趋势,与2007年比较,2009年及2010年均上升(P<0.01)。结论:血气缺陷标本所占比率逐年下降,标本凝固是标本缺陷的主要原因,应完善动脉血气标本采集的操作规范与流程,减少缺陷样本的发生。Objective： To analyze the occurrence rate and causes of arterial blood gas specimens defects, then improve the prophase quality control of arterial blood gas analysis. Methods： A total of 2594 arterial blood gas defect specimens were retrospectively analyzed among 314 229 samples from January, 2007 to December, 2010. Results： The overall occurrence rate of defect specimen was 0.83%. And this rate decreased year by year from 2007 to 2010 （P〈0.01）. The causes for defect specimen were as follows： coagulation samples （45.2%）, inadequate blood （22.3%）, with bubbles （18.9%）, identification problem （10.3%）, pollution 0.3%）. Almost half of the unqualified specimens were coagulation problems, but this problem decreased year by year （P〈0.01）, then the percentage of identification problem and bubble problem percentage were at a rising trend （P〈0.01）. Conclusion： The rate of arterial blood gas defects specimens decreased gradually from 2007 to 2010, coagulation was the main reason. Arterial blood gas specimen collection procedure should be strictly operated by nurses.
