Childbirth - a physiological process, but every woman he usually takes in his own way.There are certain limits of physiological norm, going beyond that is considered an anomaly.For such an anomaly in labor are rapid delivery.
How is the physiological childbirth
Hippocrates believed that the physiological labor lasted no more than a day since the beginning of the fights (18 hours for the first birth and 12 hours for the multiparous).Currently, delivery continues at least for a long time - it helps to reduce maternal and child injuries.
during physiological childbirth are three periods:
- period of disclosure of the birth canal, or fights - it goes from 13-18 hours in nulliparous to 10-11 hours in multiparous;
- during expulsion of the fetus (attempts) - duration of 1-2 hours in nulliparous women to half an hour in multiparous;
- successive period - the birth of the placenta - the duration of half an hour both nulliparous and multiparous women.
Why are there rapid delivery
«Parturient" the queen is in the contraction of muscles (tone) and increased arousal.The excitability of the uterus - is the property of her muscles to contract under the influence of special substances that are released in the body of a woman giving birth under the influence of the cerebral cortex - the team of their separation comes when the fruit ripens.
Distinguish normal tone of the uterus, low and high.Increased tone of the uterus is considered a violation of labor.At the same time contractions become very strong, prolonged and frequent (more than five contractions in 10 minutes).Considerably shorter becomes the slow relaxation of the muscles of the uterus, they do not have time to rest and recharge energy.Deliveries in that case lasts no more than 1-3 hours, and sometimes less, then overstrain muscles of the uterus affects their full relaxation (atony).
Such rapid delivery is called, they are often seen in women with an increased excitability of the total (for example, nervousness, increased thyroid function).In this case violated the regulation of labor on the part of the central nervous system and the impulses coming from the uterus to the brain is insufficient controls its higher parts - the cerebral cortex.
How is the rapid delivery
Rapid deliveries begin suddenly, when nothing heralds their beginning.Immediately begin intense, frequent and prolonged struggle, which quickly lead to full disclosure of the birth canal.Woman in labor at the same time are usually too excited, which negatively affects its behavior during delivery, including on the implementation of a team of doctors.
Once depart amniotic fluid, immediately go into battle strong and frequent attempts.Many times women giving birth are sometimes quite isolated attempts to give birth to first child, and then the placenta.Often these genera caught a woman in the street, in stores, and where she has to give birth (birth, street).
hazards that may occur during rapid delivery
With strong and frequent muscle contractions of the uterus blood circulation in the uterus and placenta, the child receives less oxygen and nutrients - it may further affect the state of his brainbrain.With the rapid advancement of the fetal head through the birth canal soft skull bones do not have time to take the desired shape for the passage, with the result that the head undergoes rapid and strong pressure, it can cause birth defects Birth injuries - than they threaten your child? and intracranial hemorrhage.
women alike during childbirth threatens premature detachment of the placenta ruptures of soft tissues of the birth canal (cervix, vagina, perineum), which in turn can cause severe bleeding.In addition, rapid delivery may cause depletion of energy resources muscles of the uterus and its full atony (relaxed).As a result of uterine atony after childbirth is not reduced, the blood vessels of the uterus, placenta associated with the department continued to gape - a so-called atonic bleeding, which is very difficult to stop.Rapid genera also contribute uterine injury that leads to the development of various diseases in the postpartum period.
How to lead the rapid delivery
Maintaining rapid delivery aimed at reducing the activity of labor: the woman in childbirth is laid on its side and general anesthesia.Deliveries take in the status of women on the side.After delivery, a careful examination of the perineum in order to identify gaps.
In the case of "street" after receipt of a woman giving birth in a maternity hospital she was treated carefully vulva disinfectants and administered tetanus toxoid.
If a woman has previously been rapid delivery, it usually is hospitalized before the due date.
