Labor

Many women are afraid of induction of labor. Is it justified? In fact there are well-established, proven methods of stimulating life. There are quite specific instructions on the use of such techniques. However, induction of labor is constantly cluttered with all sorts of legends and rumors. Why is that?

How is the generic activity

At birth there is an opening of the birth canal with simultaneous expulsion of the fetus. An indication of the normal course of labor is a dilatation of the cervix, which is measured in centimeters (full cervical dilation is 10 cm). The normal rate of cervical dilatation during labor about 1 cm per hour. If the expansion is slower, the new mother may need any stimuli.

The main indicators of the functional state of the uterus during childbirth is its tone and excitability. By lowering the tone of the uterus The tone of the uterus - the most important indicator for pregnant women   and cease attempts child can "get stuck" in a woman's birth canal. This condition is called uterine inertia. The intensity, duration and frequency of contractions insufficient birth canal expanded slowly. The weakness of the labor can be both primary and secondary, and it usually requires stimulation.

The primary weakness of labor

The primary weakness of labor arises from the very beginning of the birth and continues throughout the period of disclosure or until birth. Such a violation is more common in nulliparous women older than 30 years, in violation of the menstrual cycle The menstrual cycle - that occurs in different phases? Transferred inflammatory diseases of the genital organs, with large fruit, multiple pregnancy, polyhydramnios, early rupture of membranes, prolonged pregnancy, obesity, after a large number of births and abortions.

This happens most often due to disturbances in the central nervous system, which regulates all generic act, or because of the changes in the uterus (abnormal development, hyperextension, and so on).

The flow of labor in the primary weakness of labor varied: Quest can be quite common, but weak and short, or enough power, but rare. Long during labor may threaten both the mother and the fetus.

Secondary weakness of labor

Secondary weakness of labor is more common at the end of the disclosure of the birth canal and the expulsion of the fetal period. It occurs much less frequently than the primary. The cause of secondary weakness of labor are all the reasons that cause the primary weakness, but have a lower severity, so manifest later. The reason can be women and fatigue after long painful contractions.

Secondary weakness of labor manifests itself lengthening delivery times, the weakening and shortening labor, and sometimes their complete cessation. Promotion of the fetus through the birth canal dramatically slows down or stops. Such a condition can lead to penetration of the infection into the uterus and hypoxia (lack of oxygen) of the fetus.

Induction of labor, its types and contraindications to it

Induction of labor - it is the activation of labor during childbirth. The stimulation may be needed for primary and secondary generic weakness. Contraindication for stimulation is a mismatch between the size of the fetal head and the size of the pelvis of women, the presence of uterine scar after surgeries, fatigue mothers, the threat of uterine rupture, malposition, or placenta, stenosis (narrowing of the stable) of the vagina.

Induction of labor may be conducted in the form of opening membranes (amniotomy), the introduction of hormones that stimulate labor (oxytocin) or promote cervical dilatation (prostaglandins).

Amniotomy

Autopsy of membranes enhances the mechanical stimulation of the fetal head of the birth canal and stimulate the production of prostaglandins hormones that contribute to the disclosure of the cervix. Reveal the bag of waters with special tool - a painless and fairly safe procedure, but it is often insufficient.

Stimulation using oxytocin

Oxytocin - a synthetic analogue of the pituitary hormone that stimulates the contraction of muscle fibers of the uterus. During labor it is usually administered intravenously, selecting dose individually, as each woman responds to oxytocin on its own. Oxytocin stimulates contractions, but does not affect the opening of the cervix, so it is used together with drugs, muscle spasms (antispasmodic - no-shpoy, papaverine).

For giving birth needed constant supervision, since oxytocin can cause increased uterine activity, which can lead to poor circulation and hypoxia (lack of oxygen) of the fetus.

Stimulation using prostaglandins

Prostaglandins - hormones that have a pronounced effect on the uterus. There are many in the amniotic fluid Amniotic fluid - how important they are to the health of women and children?   and they are able to revitalize the muscles of the uterus and its neck. During stimulation administered in the form of a gel or a candle, at least - intravenously. Prostaglandins provide sufficiently many side effects such as nausea, vomiting, diarrhea, excessive stimulation of uterine contractions, and so on.

In order to not be afraid of induction of labor, you need to trust your doctor, who will take you labor, and, consequently, become better acquainted with him in advance.
