摘　　要：目的探讨危重症患者周围动脉和外周静脉血气分析的差异性。方法选择2017年10-12月我院急诊入ICU的危重症患者35例,同时采集周围动脉血和外周静脉血,行血气分析检验,将所得结果进行统计学分析。结果 35例患者动脉血和静脉血的pH值、二氧化碳分压、碳酸氢根浓度及碱剩余差异均无统计学意义(P>0.05);氧分压差异有统计学意义(P<0.001)。结论危重症患者的周围动脉与外周静脉的血气分析酸碱状态结果无显著性差异,对于采集动脉血标本困难、存在高风险且无中心静脉导管留置的患者可采用外周静脉血气分析快速了解患者的酸碱状态。Objective To investigate the difference of peripheral arterial and venous blood gas in critically ill patients.Methods 35 cases of ICU critically ill patients in our hospital from October 2017 to December 2017 were selected.Peripheral blood and peripheral venous blood were collected at the same time.Blood gas analysis was used to analyze the blood gas analysis.The results were compared by statistical software.Results There was no significant difference between the pH value of the arterial and venous blood,the partial pressure of carbon dioxide,concentration of bicarbonate and alkali remainder of the 35 cases.There was not statistically significant(P >0.05).There was a significant difference in oxygen partial pressure(P<0.001).Conclusion The blood gas analysis of peripheral arteries and peripheral veins of critically ill patients has no significant difference.Patients who have difficulty in collecting arterial blood samples with high risk and no central venous catheter indwelling can use peripheral venous blood gas analysis to quickly understand the patient's acid-base state.
