海军飞行人员疗养前后红细胞和血红蛋白的变化及其相关性分析

Changes in red blood cells and hemoglobins of naval aviators before and after recuperation in the convalescent hospital and related analysis

目的探讨海军飞行人员疗养前后红细胞和血红蛋白的变化及其相互关系。方法分析海军85名机型一、59名机型二、42名机型三飞行人员疗养前后红细胞数量、血红蛋白含量变化,并采用直线相关回归法分析其相关性。结果疗养前后海军飞行人员红细胞数、血红蛋白含量均在正常参考范围内。疗养后红细胞数下降、血红蛋白含量升高。疗养后飞行人员红细胞数与血红蛋白含量相关性更密切,机型三飞行人员红细胞数与血红蛋白含量相关性比机型一、机型二飞行人员密切。结论不同机型和飞行任务影响飞行人员红细胞数和血红蛋白含量及其相互关系,疗养可以改善飞行人员血液质量。

Objective To investigate changes in red blood cells and hemoglobin levels of naval aviators before and after recuperation in the convalescent hospital and related analysis. Methods To analyze changes of red blood cell and hemoglobin counts in the naval aviators of type I aircraft （85 aviators）, type Ⅱ aircraft （59 aviators） and type Ⅲ aircraft （42 aviators） before and after recuperation in the convalescent hospital, and their relationship was analyzed by using linear regression method. Results Red blood cell and hemoglobin counts in the naval aviators both before and after recuperation in the convalescent hospital were all within normal ranges. Red blood cell counts decreased, while hemoglobin levels elevated, after recuperation. Closer correlation between red blood cell counts and hemoglobin levels could be noticed in the aviators, following recuperation in the convalescent hospital. The correlation between red blood cell counts and hemoglobin levels in type Ⅲ aviators seemed to be closer than that of the type Ⅰ and type Ⅱ aviators. Conclusion Different aircraft types and different flying operations had impact on red blood cell counts and hemoglobin levels, and recuperation could improve the blood quality of aviators.
