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。
Objective To investigate the changes of cardiac hemodynamics during cesarean section and vaginal delivery in viral myocarditis (VMC). Methods Fifteen patients with vaginal delivery in the VMC group underwent different mode of delivery (26 in cesarean section and 6 in vaginal delivery) were compared with those in vaginal delivery without heart disease (NHD) group. The changes of cardiac output (CO), heart rate (HR), stroke volume SV), ventricular ejection time (VET), ejection rate (EVI) and other cardiac function indicators during labor were compared. Results There was no significant difference between the two groups in the mode of delivery of VMC during labor and the change of parameters of cardiac output during delivery. The changes of cardiac output were significantly different between the delivery of the fetus and the placenta , But within 1 hour after childbirth have changed back. Conclusions Pregnant women with no viral myocarditis without obvious myocardial ischemic injury and without malignant arrhythmia can well tolerate the need of normal vaginal delivery.
