【摘要】 本实验共用家兔38只,对产后、分娩过程中及不同孕期的子宫肌电进行了体表法记录并同步描记宫内压。同时还采用埋植电极于子宫肌的直接记录法与体表法进行了同步对比记录。结果表明在产后和分娩过程中体表法能记录到与直接法相似的具有特定波型的子宫肌电,并且子宫肌电活动的变化可反映子宫功能的变化孕期在29天以前的家兔体表法记录不到子宫肌电。更多还原

【Abstract】 Electrical activity of uterine smooth muscles was investigated by means of abdominal skin-electrodes in 38 rabbits during the periods of pregnancy, parturition and postparturition, At the same time, the internal record, by implanting electrodes in the myometrium, was employed in order to compare with the external record, The intrauterine pressure was simultaneously recorded through a rubber balloon. The results showed that electrical activity with special pattern could been recorded by the external record in postparturition and during labor and that the variation of uterine function could been reflected by the changes of the electrical activity.更多还原
