同一时间段内动、静脉血血红蛋白含量的相关性分析

Correlation analysis of hemoglobin content in artery and vein at the same time

目的分析动脉血气分析与静脉全血细胞分析测定HGB(hemoglobin,HGB)浓度的相关性。方法随机抽取77例动脉血标本与84例静脉血标本分别于ABL835血气分析仪和Sysmex XE-5000全血细胞分析仪检测并比对其测量结果;随机抽取同时采集动、静脉血并对应进行动脉血气分析和全血细胞分析的394例患者,分析其检测HGB结果的相关性。结果 Sysmex XE-5000全血细胞分析仪精密度高于ABL835血气分析仪,而血气分析仪检测动、静脉血HGB结果均略高于全血细胞分析仪,且差异均有统计学意义(P均<0.05);动、静脉血两种方法检测结果均呈明显正相关(r=0.997,r=0999,P均<0.05)。同一时间动、静脉血HGB全血细胞分析测量结果高于血气分析结果,二者差异有统计学意义(P<0.05),且两种方法检测结果呈高度正相关(r=0.992,P<0.05)。结论准确的动脉血气分析HGB结果可暂时替代静脉全血细胞分析HGB结果,并推断动脉中HGB含量低于静脉血约2 g/L。

Objective To analyze the correlation of hemoglobin （HGB） concentration detected by the arterial blood gas analysis and venous whole blood cell analysis. Methods 77 cases of arterial blood samples and 84 cases of venous blood samples were randomly selected and then detected respectively with ABL835 blood-gas analyzer and the Sysmex XE-5000 hematology analyzer, and the results were compared. The arterial and venous blood samples of 394 cases were drawn randomly at the same time. Then the HGB results correla-tion of these samples who undergone the blood-gas analysis and the whole blood cell analysis were analyzed. Results The precision of Sysmex XE-5000 hematology analyzer was higher than ABL835 blood-gas analyzer. The HGB results from blood-gas analyzer were all slightly higher than the hematology analyzer , and the differ-ences all had statistical significance（Pall〈0.05）. The arterial and venous blood HGB results of two methods all shown positive correlation （r=0.997, r=0.999, Pall〈0.05）. The HGB result of whole blood cell analysis was higher than blood-gas analysis at the same time, and the difference had statistical significance（P〈0.05）, The results of two methods shown positive correlation （r=0.992, P〈0.05）. Conclusion The precise results of HGB by arterial blood-gas analyzer can temporarily replace the results of hematology analyzer , and arterial blood HGB content is less about 2 g/L than venous blood according the extrapolation.
