Abstract

BACKGROUND

Arterial blood gas analysis (ABGA) plays a vital role in emergency and intensive care, which is affected by many factors, such as different instrumentation, temperature, and testing time. However, there are still no relevant reports on the difference in discarding different blood volumes on ABGA values.

METHODS

We enrolled 54 patients who underwent thoracoscopic surgery and analysed differences in blood gas analysis results when different blood volumes were discarded from the front line of the arterial heparin blood collector. A paired t test was used to compare the results of the same patient with different volumes of blood discarded from the samples. The difference was corrected by Bonferroni correction.

RESULTS

Our results demonstrated that the PaO2, PaCO2, and THbc were more stable in the 4th ml (PaO2 = 231.3600 ± 68.4878 mmHg, PaCO2 = 41.9232 ± 7.4490 mmHg) and 5th ml (PaO2 = 223.7600 ± 12.9895 mmHg, PaCO2 = 42.5679 ± 7.6410 mmHg) blood sample than in the 3rd ml (PaO2 = 234.1000 ± 99.7570 mmHg, PaCO2 = 40.6179 ± 7.2040 mmHg).

CONCLUSION

It may be more appropriate to discard the first 3 ml of blood sample in the analysis of blood gas results without wasting blood samples.

摘要

背景

动脉血气分析（ABGA）在急诊和重症监护中起着至关重要的作用，它受到许多因素的影响，如不同的仪器、温度和检测时间。然而，关于丢弃不同血量对ABGA值影响的差异仍无相关报道。

方法

我们纳入了54例行胸腔镜手术的患者，分析从动脉肝素采血器前端丢弃不同血量时血气分析结果的差异。采用配对t检验比较同一患者不同血量丢弃样本的结果。差异经Bonferroni校正。

结果

我们的结果表明，第4毫升（PaO2 = 231.3600 ± 68.4878 mmHg，PaCO2 = 41.9232 ± 7.4490 mmHg）和第5毫升（PaO2 = 223.7600 ± 12.9895 mmHg，PaCO2 = 42.5679 ± 7.6410 mmHg）血样中的PaO2、PaCO2和总血红蛋白（THbc）比第3毫升（PaO2 = 234.1000 ± 99.7570 mmHg，PaCO2 = 40.6179 ± 7.2040 mmHg）血样中的更稳定。
