onset of labor is the appearance of regular contractions, which begins under the influence of cervical dilatation.Also, this process contributes to the pressure and weight of the membranes.Gradual expansion continued for 8-14 hours and ends amniorrhea and full disclosure.Then the expulsion of the fetus directly.
woman's uterus is a hollow organ composed of muscle tissue.Around the throat is a ring of muscle - the cervix.Throughout pregnancy, it is closed.The entrance is protected by a mucous plug, which is a barrier for the penetration infections.The cervix is quite dense, takes the form cylinder 3 cm in width and about the same length.In the center of the cervical canal passes.After 32-34 weeks of pregnancy occurs gradually cervical dilatation, softening it.
For internal inspection of cervix misses fingertip.The fruit begins to descend in the pelvis, thereby creating a certain pressure on the cervix, which contributes to its further disclosure.By 36-38 weeks the cervix
With each contraction under the influence of hormones occurs first cervical dilatation on a finger, then two.At the time of delivery of the full expansion of 10 centimeters in diameter.With this degree of disclosure of the head and torso of a baby can pass through the birth canal.
total in the first stage of labor divided into three phases:
Also during the active phase usually occurs rupture of membranes by increasing intrauterine pressure.The liquid volume of about 150-200 ml.In a normal amniotic fluid should be clear and bright.If cervical dilatation of 6-8 centimeters of water not recovered spontaneously, it is usually the obstetrician makes amniotomy - opening membranes.
Throughout the first stage of labor is carried out constant monitoring of the condition of the mother and fetus.Keep an eye on the progress of labor, lack of complications, well-being pregnant (heart rate, blood pressure, discharge from the genital tract, temperature), cervical dilatation.
for timely diagnosis of fetal hypoxia during labor and the prevention of possible fetal death is held constant kardiomonitorny control.The most commonly used indirect cardiotocography, where the frequency of the heart rate is measured by means of ultrasound.
The fact that the birth canal of women prepared indicates cervical dilatation on the finger and more.It determined by this manual method, which is called an internal examination.His conduct in the sterile gloves, and entrance to the vagina is treated with a disinfectant solution.The midwife may thus determine the readiness of the cervix, a condition of amniotic fluid, the baby's position and height of the head state.
If the cervix is not disclosed, and the woman approached term births, in this case do stimulation.Also it is usually carried out after 40 weeks of pregnancy, the placenta is aging and can not fully carry out its functions.Artificial preparation os carried out in two ways: medication and non-drug.
first method is used only in a hospital, with the cervix is carried out with the help of medicines:
Drug-free methods can be used alone, but be very careful:
In some cases requires hospitalization of women in pre-hospital to prepare for the upcoming birth.Doctors hold it in-depth laboratory, clinical and instrumental examination to select the timing and delivery methods.
