分娩活动是使产妇和胎儿机体产生特定变化的一种应激反应,其变化目的在于保持胎儿机体内环境的恒定,特点是对缺氧和酸中毒的敏感性增强。同时,胎儿的适应能力加强,可根据氧化还原反应来判断。
Childbirth is a stress response that produces specific changes in the maternal and fetal body. The purpose of the change is to maintain a constant fetal environment and to be characterized by increased sensitivity to hypoxia and acidosis. At the same time, the fetus’s ability to adapt to strengthen, according to the redox reaction to judge.
