目的分析在生化检验中采用血气分析的动脉剩余血以减少重症患者检验性失血的可行性。方法采用固体肝素锂锌平衡的动脉血气针采集动脉血，将剩余动脉血用于生化检验（试验组），并且在对静脉血进行采集并用于生化检验（对照组），对这两组的检测结果和患者的失血量进行对比和分析。结果两组方法在总蛋白和直接胆红素以及肌酐等上进行比较，试验组优于对照，差异显著，具有统计学意义（P﹤0.05）。结论使用血气分析的动脉剩余血进行生化检验，结果准确，可以有效地减少重症患者的失血量。“,” objective to analyze the residual of blood gas analysis in biochemistry inspection artery blood to reduce the serious patients examine the feasibility of blood loss. Methods using solid heparin lithium zinc balance of arterial blood gas needle acquisition arterial blood and the remaining arterial blood used for biochemical test (test group), and the venous blood were col ected and used in biochemical test (control group), the test results of the two groups were compared with patients with blood loss and analysis. Results in the two groups in terms of total protein and direct bilirubin and creatinine were compared, the treatment group is superior to the contrast, the significant difference, statistical y significant (P ﹤ 0.05). Conclusion using arterial blood biochemical inspection remaining blood gas analysis, results are accurate, can effectively reduce the patients with severe blood loss.
