富氧水预防急性高原反应的疗效观察

目的研究富氧水对急性高原反应的预防作用。方法将80名青年战士等分为两组,使用双盲法,在海拔3700 m某地,实验组服用富氧水,对照组服用安慰剂。在其抵达海拔5300 m驻地后第3天,采用《急性高原反应的诊断和处理原则》(中华人民共和国国家军用标准,GJB-1098-1991)对其进行急性高原反应评分;第7天,采用《高原习服评价指标与方法》(中华人民共和国国家军用标准,GJB-4301-2002)对其进行高原习服基础生理指标测定。结果服用富氧水后,急性高原反应发病率明显降低,两组相比统计学差异非常显著(P<0.01)。结论富氧水可提高人体在缺氧条件下的血氧饱和度,降低急性高原反应的发病率,缩短人体在高原缺氧条件下习服的时间。

Curative Effect of Heavy-oxygen-enriched Water on Obviating Acute Altitude Reaction

Objective To observe the curative effect of heavy-oxygen-enriched water(HOEW) on obviating acute high altitude reaction.Methods The study was double-blinded,randomized and placebocontrolled.Eighty youth were divided into trial group and control group.In the way to the habitat,they drank either HOEW or placebo until the third day after they arrived.Acute high altitude reaction score were recorded using military standard GBJ 1098-1991 "Principle of Diagnosis and Treatment on Acute High Altitude Reaction"and basic altitude acclimatization were determined using military standard GJB 4301-2002"Estimated Index and Method on High Altitude Acclimatization".Results Compared with that in the control group,acute high altitude reaction rate in the trial group reduced significantly(P<0.01).Conclusion HOEW can boost SaO2 in hypoxic environmental,degrade acute high altitude reaction rate and enhance acclimatization.
