To find the similarities and dissimilarities between the activity of the human smooth muscles in the cervix and in the uterine corpus at the onset of induced labour.
Electromyographic activity was measured in 14 primiparous women after amniotomy. The data were sampled and stored digitally in real time. For statistical analysis, the first 20 min of recordings following amniotomy were analyzed. The ratio between the mean activity at a given time and the mean activity over the whole 20 min was used for the comparison between the cervical and uterine activity.
The analysis of correlation showed that the electromyographic activity in the cervix differed from that in the uterine corpus in the majority of the enrolled cases.
The muscular activity in the cervix is independent of that in the uterine corpus at the onset of induced labour.
找出引产开始时子宫颈和子宫体中人类平滑肌活动的异同。
对14名初产妇在破膜后进行肌电图活动测量。数据实时采样并数字存储。为进行统计分析，对破膜后最初20分钟的记录进行分析。用给定时间的平均活动与整个20分钟的平均活动之比来比较宫颈和子宫的活动。
相关性分析表明，在大多数纳入病例中，宫颈的肌电图活动与子宫体的不同。
引产开始时，宫颈的肌肉活动独立于子宫体的肌肉活动。
