摘　　要：目的:探讨不同质量控制方法对减少动脉血气标本采集量的效果。方法:第一阶段对2个ICU病区(A组和B组)的护士进行诊断性失血的相关培训,第二阶段将A、B两组使用的动脉血气针规格由3 ml更换为1 ml,另一个病区的护士(C组)作为对照组。两种方法进行干预后,分别记录各组动脉血气标本采集量并进行比较。结果:第一阶段中,A组平均标本采集血量为(1.33±0.33)ml,略少于C组的平均采血量(1.38±0.35)ml,差异无统计学意义(P>0.05);B组平均标本采集血量为(0.88±0.25)ml,明显少于C组和A组,组间差异均有统计学意义(P值均<0.01)。第二阶段将血气针规格由3 ml更换为1 ml后,A、B两组采集的平均标本血量分别为(0.74±0.15)ml和(0.69±0.16)ml,和同组第一阶段相比,差异均有统计学意义(P值均<0.01)。结论:动脉血气针由3 ml到1 ml的更换能有效地减少诊断性失血量。Objective：To explore the effects of different quality control methods to decrease the amount of sample collected for blood gas analysis.Methods：During period 1,each nurse in two ICU wards was instructed about diagnostic blood loss.During period 2,3 ml arterial blood gas needles were replaced by 1 ml needles in group A and group B,and another ward（group C） served as the control group.After intervented with two methods,the measurements of collected sample amount were recorded and compared separately.Results： During period 1,the average sample volumes from group A were（1.33±0.33）ml,less than those from group C slightly,there was no statistical difference（P0.05）.The average sample volumes from group B was（0.88±0.25）ml,less than from group C and A obviously,and the difference between each group was significant（P0.01）.During period 2,after the 1-ml needles instead of the 3 ml needles,the average sample volumes from group A and B were（0.74±0.15）ml and（0.69±0.16）ml,compared with the same group during period 1,there was statistical significance（P0.01）.Conclusion：The replacement of the arterial blood gas syringe specification from 3 ml to 1 ml could reduce the amount of diagnostic blood loss availably.
