摘要
为探讨正常孕妇和妊高征患者的血液动力学参数,采用无创妊高征血液动力学监测系统(MP-PIH),序贯监测孕早、中、晚期正常孕妇30例,非孕妇60例,妊高征(轻、中、重度)患者46例。非孕妇和正常孕妇属正常排,微循环、流量、流速、流态正常,两者无明显差异。妊高征正常排:CI(2.85±0.39)L.min-1/m2,ALK(0.04±0.01)1/s,ALT(19.56±2.46)s,TM(28.23±3.55)s,与正常孕妇无显著差异。高排低阻:CI(4.84±0.41)L·min-1/m2,ALK(0.06±0.01)1/s,ALT(11.42±0.95)s、TM(16.48±1.35)s。心排量>4L·min-1/m2,表明心肌代偿性加强收缩,血流速加快经微循环直捷通路,缺乏与组织细胞间的营养、代谢交换。低排高阻:CI(2.09±0.28)L·min-1/m2,ALK(0.03±0)1/s,ALT(26.78±4.02)s,TM(38.65±5.76)s。心排量<2.5L·min-1/m2,血流量少,流速慢,微循环淤血,组织细胞缺血、缺氧。
Objective:To investigate the hemodynamic parameters in normal pregnant women and the women with PIH.Design:Hemodynamic parameters including cardiac function and microcirculation were prospectively studied in 30 normal pregnancies and 46 cases of PIH.Results:Parameters of normal pregnancies:CI(3 00±0.74)L.min -1 /m 2,microcirculation ALK(0 04±0.01)1/s,ALT(19.51±4.81)s,TM(27 92±7 16)s.They were in normal range.Women with PIH:①In patients with normal cardiac output,CI(2 85±0.39)L.min -1 /m 2,ALK(0.04±0.01)1/s,ALT(19.36±2.46)s,TM(28.23±3.55)s.There was no significant difference when comparing with normal pregnancy group.②In patients with high output,CI (4.84±0.41)L.min - 1/m 2,ALK(0.06±0.01)1/s,ALT(11.42±0.9)s,TM(16.48±1.35)s.It meant that high output was the cause of compensatory myocardiac hypercontractility pushing the blood into the direct pathway with insufficient nutrition and oxygen providing tissues and cells.In patients with low output:CI(2.09±0.68)L.min - 1/m 2,ALK(0.03±0)1/s,ALT(26.78±4.02)s,TM(38.65±5.76)s.It meant that the low blood flow into microcirculation and blood stasis causes hypoxemia and ischemia of tissues and cells.Conclusion:An understanding of hemodynamic parameters,especially,the changes of microcirculatory blood flow would be helpful in deciding fluid therapy,as well as potentially useful in prevention of cardiodysfunction and pulmonary edema. \ \
