摘要
目的探讨进驻海拔5 000 m以上地区对青年心肺X线的影响。方法对进驻海拔5 000 m以上地区1年及返回平原1年的同一群体144名青年在高原现场拍摄正、侧位X线胸片并与上高原前相比较。结果上高原1年后心脏长径及心脏面积缩小,差别有高度显著性(P<0.001);心脏宽径,心脏深径及心脏体积增加,差别有高度显著性(P<0.001);右心房宽径,右心房高径、左室壁厚度、肺面积、升主动脉横径、主动脉结横径、肺动脉干横径、肺动脉段突度及右肺下动脉横径增加,差异均有高度显著性(P<0.001)。返回平原1年后,以上各X线指标较上高原前均增大,差异有高度显著性(P<0.01)。结论进驻海拔5 000 m以上地区对进驻青年心肺血管形态影响较大,返回平原1年后难以恢复到上高原前水平。
Objective To explore the cardiopulmonary X-ray changes on young soldiers garrisoning to the regions with a 5000 meters＇ altitude. Methods A total of 144 youths, who had garrisoned to regions of 5 000 meters above the sea level for one year and then returned to plain for one year, were taken orthophoric and lateral chest roentgenograms. The results were then compared with the chest roentgenograms which were taken before their going to the high altitude areas. Results After garrisoning at high altitude for one year, the length diameter of heart reduced significantly （ P 〈0. 001 ） ; width diameter, depth diameter and volume of heart increased significantly （P 〈0. 001 ）; some parameters, such as wide diameter of right atrium, height diameter, thickness of left ventricular wall, area of lung, transverses diameter of aortic knob, transverse diameter of pulmonary trunk, protrusion of pulmonary artery section and transverse diameter of fight inferior pulmonary artery, increased significantly （ P 〈 0. 001 ）. After returned to plain for one year, the above mentioned indexes increased significantly when compared with those before entering high altitude area （P 〈 0.01 ）. Conclusion There is severe infection on the cardiopulmonary configuration of young soldiers garrisoned to the regions of 5000 meters above the sea level, and it can not resume after they return to the plain for one year.
