某部高原抗震救灾官兵返回平原后的血液学指标变化

Hematological changes in officers and soldiers returning to plain from high altitude after earthquake relief work

目的:了解高原脱适应者的血液学变化。方法:选取某部参加玉树抗震救灾任务110 d后返回平原的1 077人,分别于返回当日、第15天、第40天取手指末梢血;另取未到高原的健康人群133人为对照组,用KX-21血液分析仪检测分析。结果:白细胞(WBC)、红细胞(RBC)、血红蛋白(HGB)、红细胞压积(HCT)、平均红细胞体积(MCV)、平均血红蛋白含量(MCH)及血小板(PLT)计数明显高于对照组(P<0.05),PLT明显低于对照组。随着从高原返回平原的时间延长,各项检测值逐渐向对照组接近。结论:高原短期暴露人群从高原返回平原后,处于高原脱适应期的血液学指标恢复更慢。

Objective：To observe the hematological changes in people with high altitude deadaptation.Methods： A total of 1 077 subjects completing 110-day Yushu earthquake relief mission were admitted in this study（experiment group）,and their finger peripheral blood were determined for routine blood test with the KX-21 blood analyzer at day 1,15 and 40 after returning to plain from high altitude.A total of 133 healthy individuals living in plain areas were served as the control group.Results： The white blood cell（WBC）,red blood cell（RBC）,hemoglobin（HGB）,hematocrit（HCT）,mean corpuscular volume（MCV）,mean corpuscular hemoglobin content（MCH） and platelet（PLT） count in experiment group were significantly higher than those in control group（P0.05）,and the PLT was significantly lower than that in control group.With the lengthening of time after they returned to the plain from the plateau,the test values were gradually closer to the control group.Conclusion： After returning to plain from the plateau,the people under short-term exposure to high altitude will have slower hematological recovery in the high altitude deadaptation period.
