目的调查飞行人员血清总胆红素指标水平分布情况,以研究血清总胆红素水平与飞行疲劳、飞行小时、飞行强度、飞行耐力等相关因素关系,并进行成因分析。方法追踪近3年健康检查中1 239名飞行人员血清总胆红素指标水平分布情况,并将结果用2统计分析。结果 3年健康检查血清总胆红素分布情况对比示异常率差异无统计学意义;血清总胆红素异常好发于20～30岁,与其他年龄段差异有统计学意义(P<0.05);血清总胆红素异常者中,当班飞行人员好发,与飞行轮休人员和从未飞行的人员相比较差异有统计学意义(P<0.001),提示血清总胆红素指标水平分布与飞行小时存在负向关系,与初飞学员是否上机参加空中飞行差异有统计学意义(P<0.05)。结论单纯胆红素增高无临床实际意义,体检医师只凭血清总胆红素指标异常判断该飞行人员身体暂不合格结论显然有失科学依据;飞行人员医学鉴定标准尚需进一步完善。
Objective To investigate the level distribution of serum total bilirubin in pilots to study the relationship between serum total bilirubin level and flight fatigue, flight hours, flight intensity, flight endurance and other related factors, and analyze the causes. Methods The distribution of serum total bilirubin level in 1 239 pilots during the past three years was traced and the results were analyzed by 2 statistical methods. Results There was no significant difference in the distribution of total bilirubin in the three-year health examination. The abnormal serum total bilirubin occurred in 20-30 years old, which was significantly different from other age groups (P <0.05) ; Among the patients with abnormal serum total bilirubin, there was a significant difference in the flight attendants (P <0.001), compared with those on the flight crew and those who never flew, suggesting that the level of total serum bilirubin There was a negative correlation between hour and hour. There was a significant difference between the first flight and the first flight when participating in aerial flight (P <0.05). Conclusions Simple hyperbilirubinemia is not clinically significant. It is obvious that medical examiners only temporarily fail to pass the conclusion that the serum total bilirubin index is abnormal and the scientific evidence is in doubt. The standards for medical identification of pilots need to be further improved.
