Generally, the total labor process is divided into three stages: the first labor process begins with uterine contraction, and the cervix gradually never opens to 10 cm. Primiparas generally need10 ~12 hours, which is much faster for multiparas.
The second stage of labor is from the opening of the cervix 10 cm (also called full opening) to the delivery of the fetus. Generally, the primipara completes it within1~ 2 hours, and the multipara is faster.
The third stage of labor is that the fetus is delivered to the fetal membrane and the placenta is completely discharged, which can be completed in a few minutes to 10 minutes. The total stage of labor ≥24 hours is called delayed labor. The first stage of labor should be over 10 hour, the second stage of labor should not exceed 2 hours, and the third stage of labor should not exceed 30 minutes. Otherwise, it is an abnormal situation and should be intervened to promote the progress of labor.
