Primiparous considered fast delivery, if they are less than 6 hours, and rapid - less than 4 hours. In multiparous - less than four and less than two hours, respectively. They can start as protracted slow opening of the cervix and the long stay of the fetus at the entrance to a small basin. Then their total duration is normal - 10-12 hours. However, the expulsion of the fetus in the period of childbirth still is shortened and is accompanied by too frequent and strong uterine contractions with minimal spaces between them.
Rapid and fast delivery - a serious pathology associated with impaired uterine function. Such delivery may be caused by increased excitability of muscle cells (this can be inherited). Another common cause - especially the nervous system of the woman, a tendency to neurosis and overstimulation in the absence of psychological readiness for labor. Metabolic disorders, increased production of thyroid hormone or adrenal glands, inflammatory gynecological diseases, severe toxemia, kidney disease can also cause rapid delivery. By rapid delivery may result in improper application of stimulant drugs. Among the risk factors for rapid delivery includes such birth in history of cervical insufficiency, the small size of the fruit combined with a wide pelvis and neuroses.
The first stage of labor, during which the cervix opens, in most cases lasts for a long time, but practically invisible to women. A sign of approaching childbirth become outpouring of water, an irresistible urge to push, feeling the baby's head in the birth canal and its promotion. Contractions begin rapidly and grow rapidly, accompanied by too frequent and strong uterine contractions with minimal spaces between them.
Rapid delivery are not without consequences for either the mother or the child. They can lead to injury and tearing of the birth canal, the divergence of the pelvic bone in the area of the pubic joints, premature detachment of the placenta, or violation of its branch in the third stage of labor - birth afterbirth. Uneven opening of the cervix and promotions of the fetus increases the risk of hypoxia and birth injuries, hematomas, internal hemorrhage. Rapid delivery is often accompanied by an increase in pressure, nausea and vomiting, rapid heartbeat.
They can not be prevented, but the course and the consequences can be mitigated - by using drugs that slow down generic activities that reduce the excitability and normalize the tone of the uterus. Several slow the advance of the baby through the birth canal can put mothers on one side or on all fours in a pose convenient for women and safe for the child.
Rapid delivery is often accompanied by an increase in pressure, nausea and vomiting, rapid heartbeat. They are fraught with stress, an increased risk of injury and subsequent complications - for both mother and child.
