目的:探讨妊娠期高血压疾病(PIH)患者病情程度与血液动力学改变的关系。方法:用MP妊高症监测仪检测妊娠期高血压疾病患者血液动力学指标,并分析其与妊娠期高血压疾病患者病情程度的关系。结果:①PIH组平均动脉压(MAP)、动脉压差(DP)、外周阻力(TPR)、血液粘度(V)较正常妊娠组明显升高,差异有统计学意义(P<0.01);②MAP、DP、TPR、V等指标在妊娠高血压组即有升高,在轻度子痫前期、重度子痫前期时,上述指标均有显著改变,且随病情加重而更趋于明显。重度子痫前期组每搏输出量(SV)、心输出量(CO)、血管顺应性(AC)较妊娠高血压组明显下降,差异有统计学意义(P<0.05);③妊娠期高血压疾病孕妇血液动力学类型主要包括:低排高阻型(41.33%)、正常排高阻型(36%)、正常阻力型(12%)、高排低阻型(8.0%)、正常排低阻型(2.67%)。结论:妊娠期高血压疾病孕妇血液动力学类型以低排高阻型、正常排高阻型为主,检测妊娠期高血压疾病孕妇血液动力学指标对判断妊娠期高血压疾病的严重程度有重要价值。
Objective: To investigate the relationship between the severity of patients with gestational hypertension (PIH) and hemodynamic changes. Methods: The hemodynamic indices of patients with hypertensive disorder complicating pregnancy were detected by MP pregnancy monitoring instrument and their relationship with the severity of hypertensive disorders in pregnancy was analyzed. Results: ①The mean arterial pressure (MAP), arterial pressure (DP), peripheral blood pressure (TPR) and blood viscosity (V) in PIH group were significantly higher than those in normal pregnancy group (P <0.01) DP, TPR, V and other indicators of pregnancy-induced hypertension have increased, in mild preeclampsia, severe preeclampsia, the above indicators have significantly changed, and with the more serious and more obvious. The stroke volume (SV), cardiac output (CO), and vascular compliance (AC) in severe preeclampsia group were significantly lower than those in pregnancy-induced hypertension group (P <0.05) The main types of hemodynamics in pregnant women include low-row high-impedance type (41.33%), normal high-resistance type (36%), normal resistance type (12% Resistance (2.67%). Conclusion: The main types of hemodynamics in pregnant women with hypertensive disorder complicating pregnancy are low-resistance type and normal-resistance type. It is important to detect the hemodynamic parameters of gestational hypertensive disorders in judging the severity of hypertensive disorder complicating pregnancy value.
