东北某野战医疗队高原驻训生理指标变化动态研究

A dynamic study of plateau physiological index changes of northeast field medical team

目的探讨初入高原地区医疗队员生理指标的变化规律,为部队在高原地区演习训练和卫勤保障提供有效的防治对策和科学依据。方法以某野战医疗队参加高原驻训的99名队员为研究对象,分别在不同的海拨高度(40 m、1 000 m、1 500 m、3 000 m、3 600 m、4 600 m)进行血压、心率及血氧饱和度指标的动态监测,并且在最高4 600 m海拨高度下,给予低流量吸氧30 min,观察吸氧前后上述生理指标的变化。结果医疗队员从平原进入高原后,在海拨3 000m以上地区血压、心率和血氧饱和度发生显著变化(P<0.05),并且随着海拔高度的增加,变化越显著;在低流量吸氧30 min后,血压、心率及血氧饱和度均得到改善(P<0.05)。结论在3 000 m以上高海拨地区,医疗队员生理指标变化显著,应采取相应的干预措施,给予一定的氧疗是有必要的,对于本身有高血压、心动过速或肺通气功能异常者应谨慎进入高海拔地区。

Objective To explore the change rule of physiological indexes of fledgling medical team during plateau military training,and the army medical support was performed as an effective prevention and treatment countermeasure as well as scientific basis. Methods High altitude military training of the 99 medical workers participated as the research object,in different altitudes（ 40 m,1 000 m,1 500 m,3 000 m,3 600 m,4 600 m） on blood pressure,heart rate and blood oxygen saturation index of the dynamic testing,and at the maximum 4 600 m altitude,the low flow oxygen was delivered for 30 minutes,then observed the changes of the physiological indexes before and after oxygen delivery. Results After the field medical team from plain approached into plateau,at an altitude of over 3 000 m the blood pressure,heart rate and blood oxygen saturation changed significantly（ P 〈 0. 05）,and with the altitude increased,change was more significant; in the low flow oxygen delivery after 30 minutes,blood pressure,heart rate and blood oxygen saturation were improved,that was statistically significant（ P 〈 0. 05）. Conclusion At over 3 000 m high altitude,physiological index changers are significant,the corresponding intervention measures should be taken,oxygen delivery therapy is necessary when there are hypertension,tachycardia,or abnormal pulmonary ventilation function. Therefore,people should be careful to enter the high altitude area.
