分娩活动是胎儿通过分娩力、产道和胎儿三者之间相适应又相对抗的复杂性活动。通常在胎儿及产道基本正常的情况下,分娩的正常进行,主要决定于产力的强弱。其宫缩的强弱与间歇的长短,可直接影响胎儿的气体交换。宫缩过强,间歇过短,使胎儿宫内缺氧,甚至危及胎儿生命,因而在产程中需要密切观察胎心率(简称FHR)的变化,以便随时发现异常情况,及时给予处理,从而降低新生儿的死亡率。
Childbirth activity is the complexity of the fetus through the childbirth force, birth canal and fetal adaptive and antagonistic. Usually in the fetus and birth canal under normal circumstances, the normal delivery, mainly depends on the strength of the force. The contractions of the strength and intermittent length, can directly affect the fetus gas exchange. Contractions too strong, intermittent too short, so that fetal intrauterine hypoxia, and even endanger the life of the fetus, and therefore need to closely observe the labor process fetal heart rate (FHR) changes in order to detect abnormalities at any time, give timely treatment, thereby reducing Neonatal mortality.
