Sünnitekitegevusega

Sünnitekitegevusega refers to the physiological processes involved in childbirth. It encompasses the complex series of events that lead to the expulsion of the fetus and placenta from the mother's uterus. This process is typically divided into three stages: dilation and effacement of the cervix, birth of the baby, and delivery of the placenta.

The first stage, labor, begins with uterine contractions that cause the cervix to thin (efface) and open (dilate). This stage can vary greatly in length, often lasting several hours. The second stage, pushing, commences once the cervix is fully dilated and involves the mother actively bearing down with contractions to move the baby through the birth canal. This stage concludes with the birth of the baby. The third stage, the placental stage, involves the uterus contracting again to detach and expel the placenta and membranes from the uterus.

Hormonal changes play a crucial role in initiating and regulating labor. Oxytocin is a key hormone that stimulates uterine contractions. Prostaglandins also contribute to cervical ripening and contractions. The biomechanics of labor involve the interaction of the fetal head, pelvis, and uterine forces to facilitate passage. Monitoring fetal well-being and maternal vital signs is an integral part of managing the labor process. Complications can arise at any stage, necessitating medical intervention in some cases. The successful completion of sünnitekitegevusega results in the birth of a newborn.
