作者将阻抗脉波换能器安装于子宫体体部内膜面上,测定宫缩和间歇期子宫体部血流量的变化,结果表明分娩初至中期,宫缩时的血流量较间歇期减少10～30%,而分娩后期及破膜后或引产时减少达50%。分娩时体位对子宫血流量及胎心率有影响。如一孕40周5天,孕妇临产入院,宫口开大4cm,宫缩间歇3分钟时,侧卧位宫缩初期子宫体部血流量一过性增加,随宫缩增强血流量减少,宫缩高峰稍过时血流量呈最低值,随宫缩减弱血流量开始增加,至后半期出现一过性增加。其后需经30
The authors will impedance pulse transducer mounted on the endometrial surface of the uterine body to measure uterine contractions and intermittent changes in blood flow, the results show that early to midpartum, contractions blood flow decreased compared with the intermission 10 to 30%, and postpartum and rupture of membranes or induction of labor reduced by 50%. Childbirth position on the uterine blood flow and fetal heart rate impact. Such as the first 40 weeks of pregnancy for 5 days, pregnant women admitted to hospital, open the mouth of the cervix 4cm, contractions intermittent 3 minutes, the lateral uterine contractions of the early uterine body blood flow increased transiently, with contractions and increased blood flow decreased contractions Peak blood flow was slightly lower when the peak, with the contraction of the weakened blood flow began to increase, to the latter half of a transient increase.
