目的探究分析高原环境下末梢血和静脉血血常规结果之间的差异。方法同时采集210例健康藏族居民的末梢和静脉血标本,对末梢血和静脉血标本进行0 h、2 h、4 h、8 h、24 h、48 h、72 h的血常规检测,并对检验结果进行统计学比较分析。结果 210例末梢血和静脉血即刻检测的血常规结果比较,差异有统计学意义(P<0.05)。末梢血与静脉血WBC、RBC、HGB、MCV、MCH、MCHC、PLT结果有高度的相关性,相关系数分别为0.982、0.987、0.994、0.988、0.992、0.982、0.919、0.832。高原环境室温保存的静脉血48 h时MCV、MCHC,72h时HCT、MCV、MCH、MCHC、PLT结果与即刻检验结果比较,差异有统计学意义(P<0.05),各时间段WBC、RBC、HGB结果与即刻检验结果比较,差异无统计学意义(P>0.05)。结论高原环境低压高寒缺氧,人群的末梢循环差,静脉血标本血常规检验结果相对稳定,建议采集静脉血为宜,偏远牧区室温静脉血标本48 h血常规检测可得到良好稳定的结果。
Objective To explore the differences between routine blood and venous blood results in plateau environments. Methods Peripheral and venous blood samples were collected from 210 healthy Tibetan residents at the same time. Blood samples were collected at 0 h, 2 h, 4 h, 8 h, 24 h, 48 h, 72 h, The test results were statistically analyzed. Results 210 cases of peripheral blood and venous blood immediately detected blood routine results, the difference was statistically significant (P <0.05). The peripheral blood and venous blood WBC, RBC, HGB, MCV, MCH, MCHC, PLT results were highly correlated, the correlation coefficients were 0.982,0.987,0.994,0.988,0.992,0.982,0.919,0.832. There were significant differences in HCT, MCV, MCH, MCHC and PLT between MCV, MCHC and MCHC at 72 h after venous blood stored at high altitude in 48 h (P <0.05), WBC, RBC, HGB results compared with the instant test results, the difference was not statistically significant (P> 0.05). Conclusion Low altitude hypothermia and hypoxia in the plateau, poor peripheral circulation in the population, blood routine test results of venous blood samples relatively stable, it is advisable to collect venous blood is appropriate, remote Wenchu warm 48 h routine blood samples can be obtained good and stable results.
