病毒性心肌炎孕产妇分娩过程血流动力学变化的初步研究

目的　探讨病毒性心肌炎产妇 (VMC)剖宫产和阴道分娩过程中心脏血流动力学的变化。方法　VMC组不同分娩方式 (剖宫产者 2 6例 ,阴道分娩 6例 )分别与无心脏病 (NHD)组阴道分娩者 15例心排量 (CO)、心率 (HR)、每搏输出量 (SV)、心室射血时间 (VET)、射血速度指数 (EVI)等心功能指标在分娩过程中的变化进行比较。结果　VMC产妇不同分娩方式的两组 ,在分娩过程中心排量等各项参数的变化过程与NHD组均无统计学意义的差异 ,都表现为在胎儿娩出和胎盘娩出后心排量显著升高 ,而在产后 1小时内都已回变。结论　无明显心肌缺血性损伤且不伴恶性心律失常的病毒性心肌炎孕妇其心脏功能能很好地耐受正常阴道分娩的需要。

The preliminary study of hemodynamic changes in pregnant women with viral myocarditis during delivery

Objective To study the hemodynamic changes in pregnant women with viral myocarditis(VMC) during casearean section and vaginal delivery.Methods The study included 32 pregnant women with VMC (26 with cesarean section and 6 with vaginal delivery) and 15 normal pregnant women as controls.The parameters of cardiac function(CO,SV and VET)were measured during delivery.Results There was no significant difference in these parameters between two groups during vaginal delivery or casearean section,and no difference compared with those of non-heart disease group.All of their cardiac output increased significantly after the delivery of fetus and placenta and returned to normal within 1 hour after delivery.Conclusion The preliminary data suggest that pregnant women with VMC who have no evidence of myocardial damage or malignant arrhythmia could be performed with vaginal delivery.
