口服营养剂对急进高原军人缺氧保护作用的研究

Anti-anoxia effect of different enteral nutrition mode on soldiers who acutely ascended to high-altitude

目的:探讨高原肠内营养剂对急进高原战士相关指标的影响。方法:选择2012-11我院体检新兵20名空运至玉树(海拔4 200m),随机分为口服强化组(10例)和普通摄食组(10例),在普通饮食的基础上,两组分别给予高原肠内营养制剂及经口摄食,比较进入高原第1、3、7天两组血气分析、营养指标、心率等。结果:口服强化组研究对象在进入高原后第7天PaO2值较普通摄食组显著改善(P<0.01);2周后血清总蛋白较普通摄食组高(P<0.05)。两组研究对象进入高原后心率均加快,后随时间推移逐渐减慢,两组间数据无统计学差异。结论:在普通饮食的基础上给予肠内营养较普通饮食,能有效改善急进高原者的呼吸功能及营养状况,提高抗缺氧能力。

Objective.To research anti--anoxia effect of different enteral nutrition modes on soldiers who acutely ascended to high altitude. Methods. Twenty trainee were randomly divided ino two groups and were sent to Yushu （above sea level 4 200 m）. GYEN group（n= 10） were given plateau enteral nutrition （GY- EN） and ordinary diet,the control group（n=10） were given ordinary diet. The arterical blood gas ,nutrit- ure index,heart rate of two groups were measured and analyzed on day 1,3,7 after they arrived at high alti- tude. Results. PaO2, total serum protein in GYEN group were significantly higher than those in control group （P〈0.01 or P〈0.05）on day 7 and 2 weeks after they arrived at high altiude. There was no signifi- cant differences in the heart rate of two groups. Conclusion. GYEN could improve nutriture and preform anti-- anoxia effects.
