目的探讨高性能战斗机飞行员血清铁浓度和红细胞指标变化的机制. 方法将来我院疗养的39名高性能战斗机飞行员作为观察组,72名歼-7、歼-8和强-5飞行员作为对照组,并比较两组飞行员血清铁浓度、红细胞指标的变化. 结果高性能战斗机飞行员较对照组飞行员血清铁浓度、血红蛋白量、红细胞平均血红蛋白含量、平均红细胞血红蛋白浓度均降低,且有统计学意义(t=3.50～7.95,P<0.01);而红细胞计数升高,且有统计学意义(t=3.01,P<0.01). 结论高性能战斗机飞行员因承受较大的加速度、缺氧、热负荷及应激,可能会引起血清铁浓度降低,红细胞计数代偿性升高,从而导致血红蛋白、红细胞平均血红蛋白含量、平均红细胞血红蛋白浓度下降,缺氧耐受力降低.因此.及早采取干预措施,及时减轻飞行疲劳和提高飞行耐力,对于保障飞行安全有重要意义.

Objective To explore the mechanism of serum iron and red blood cell changes in high performance fighter pilots. Methods Thirty-nine high performance fighter aircraft pilots were selected as test group while other 72 fighter and attacker pilots were in control group.The serum iron and red blood cell index were compared between groups. Results Pilots in test group showed significantly lower serum iron,hemoglobin,mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration than those of other pilots' in control group (t=3.50-7.95,P<0.01) but red blood cell was counted significantly higher (t=3.0 1,P<0.01). Conclusions Changes happened on high performance fighter aircraft pilots indicate that they are undertaking higher working loads such as acceleration,hypoxia.heat and stress.And these would be the reasons of resulting in lower serum iron,higher compensatory red blood cell indices,and lower hemoglobin,mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration,subsequently the poor hypoxia tolerance.Therefore,intervention measures are suggested with timely erythrocyte indices monitoring in order to release fatigue and ensure safety.
