Các giai đoạn chuyển dạ từ cơn co đến khi sinh

#manthai #thaisan #chuyenda Labor during childbirth is a completely normal physiological process of all pregnant women to help bring the fetus and its appendages out of the body. Each pregnant woman will have different signs of labor and monitoring the onset of labor will help this process take place safely and smoothly. Labor is a progression of many phenomena, the most important of which are labor contractions that gradually dilate the cervix and result in the fetus and placenta being delivered. The labor process is coordinated between the cycles of labor contractions and the dilation of the cervix, resulting in the fetus and placenta being delivered. The duration of labor varies from person to person and depends on many factors, such as the force of contractions, the birth canal, the mother's pelvis or the position of the fetus, the size of the fetal head. In women giving birth to their first child, labor usually lasts longer than in women giving birth to their second child because the cervix opens more slowly and the perineum is firmer, with an average time of 16 to 24 hours, while in women giving birth to their second child, it only takes 8 to 16 hours. The stages of labor include: Stage 1: Cervical effacement, this stage is calculated from the time of actual labor until the cervix is ​​fully dilated: the average time is 15 hours. This stage is divided into 2 periods: Latent period: 8 hours. Active period: 7 hours. Stage 2: Fetal expulsion from when the cervix is ​​fully dilated until the fetus is delivered. First child: 30 minutes - 2 hours, average 50 minutes. Second child: 15 minutes - 1 hour, average 20 minutes. Stage 3: Delivery of the placenta from the time the fetus is delivered until the placenta is delivered takes an average of 5-30 minutes. Pregnant women can know they are about to give birth through signs of labor such as: pink mucus, uterine contractions, amniotic fluid leakage and changes through vaginal examination... In short, if there is one of the above signs of labor, pregnant women need to go to the hospital immediately to monitor the progress of labor as well as be ready for emergency assistance if necessary.
