采用脉搏波法对不同高海拔地区妊娠妇女的血液动力学监测

目的：预测高原地区妊娠妇女血管舒缩的亚临床变化，及早发现妊高征患者，降低发病率。方法：利用北京易思医疗器械有限公司MP妊高征监测系统对西宁、海西、玉树三个不同海拔地区300例正常妊娠妇女进行血液动力监测。结果：由于海拔差异，其波型系数(K)、外周阻力(TPR)、心脏指数(CI)、血液粘度(V)、平均滞留时间(TM)、平均动脉压(MAP)、心率(HR)7项血液动力学参数出现不同程度偏差。结论：MP妊高征监测系统的7项功能参数的正常范围不适合高原地区妊高征的诊断。

Sphygmo-Detection of Hemodynamics in Women in Pregnancy at Different Altitude

Objective: To predict the sub-clinical changes of vasomotion in women in pregnancy at different altitudes. Methods: A total of 300 women in pregnancy, who were living in xining (2 260m), haixi (3 000m) and yushu (3 680m) area, were detected on hemodynamics using MP hypertension in pregnancy detecting system. Result: The indices such as K, TPR, CI, V, TM, MAP and HR were found to have a difference at various altitudes. Conclusion: The normal diagnostic value of K, TPR, CI, V, TM, MAP and HR defined by MP hypertension in pregnancy detecting system were invalid for the women living at high altitude.
