阴道置PGE_2栓剂可作中期妊娠引产,但前列腺素在妊娠时使用对心血管的影响尚不明瞭,尤其对妊娠合并心脏病者更不清楚。目前高血压或心血管疾患是使用PG栓剂的相对禁忌症。本文研究中期妊娠用PGE_2阴道栓剂引产时心输出量的变化。共选择10例,胎龄15～23周,其中3例是死胎。测定心输出量是通过超声多波勒计算仪测出主动脉直径乘血流速度及心率而计算出。测定对象取15度半卧位。在用药及用药后宫缩间隙中进行,2分钟内作3次测定,所得平均值作为心输出量。每隔3～4小时阴道置PGE_2栓剂一次,每次20mg,最少
Vaginal PGE 2 suppository for mid-term pregnancy induced abortion, but the prostaglandin in pregnancy when the impact on cardiovascular is not clear, especially for pregnant women with heart disease even more unclear. Currently, hypertension or cardiovascular disease is a relative contraindication to the use of PG suppositories. This study was to investigate the changes of cardiac output during induction of labor with PGE 2 vaginal suppository in the second trimester. A total of 10 cases were selected, gestational age 15 to 23 weeks, of which 3 cases of stillbirth. The cardiac output was measured by measuring the diameter of the aorta by blood flow velocity and heart rate using an ultrasound Doppler calculator. Determination of objects to take 15 degrees semi-recumbent position. Contraindications in the contractions after medication and medication, 3 times within 2 minutes for determination, the average as the cardiac output. Every 3 to 4 hours vaginal PGE_2 suppository, each 20mg, at least
