【摘要】：目的:观察坑道内半密闭环境对人体的影响,为进驻坑道提供防护依据,以减少环境对人体的负面效应。方法:用血液分析仪、全自动生化仪及特殊蛋白分析仪对12名受试者按试验前、中、后3次进行血液指标监测及两次重点复检。并对自觉症状作问卷调查。结果:39项血液指标3次监测均为正常或基本正常的有33项,占84.6%。乳酸脱氢酶有7例在试验期间高于正常值。受试者有半数以上人员有轻度头昏、头痛、胸闷、乏力等自觉症状,其中关节痛较为明显。结论:血液指标监测结果及出现的自觉症状大多数较轻,且出坑道后1~4 d消失,认为坑道内半密闭环境在短期内对人体基本无明显不良影响。对乳酸脱氢酶结果偏高及关节痛症状需要进一步探讨。
[Abstract]:Aim: to observe the influence of semi-sealed environment on human body in tunnel, and to provide protective basis for entering tunnel, so as to reduce the negative effect of environment on human body. Methods: blood indexes were monitored by blood analyzer, automatic biochemical analyzer and special protein analyzer in 12 subjects before, during and after the test, and the blood indexes were monitored and re-examined twice. Self-conscious symptoms were investigated by questionnaire. Results: 33 (84.6%) of 39 blood indexes were normal or basically normal. Lactate dehydrogenase (LDH) was found to be higher than normal in 7 cases during the test period. More than half of the subjects had mild dizziness, headache, chest tightness, fatigue and other conscious symptoms, among which joint pain was more obvious. Conclusion: most of the monitoring results of blood indexes and self-conscious symptoms were mild and disappeared 1 day after the passage. It was concluded that the semi-sealed environment in the tunnel had no obvious adverse effect on human body in a short period of time. The results of lactate dehydrogenase were higher and the symptoms of arthralgia needed to be further discussed.
