The abnormal Duration of the preliminary period, depending on the individual circumstances of each women may vary from 6 hours to 24–48 hours. In some women it can take several days.
Pathological preliminary period, in most cases, leads to the complication of the course of labour. Many women in childbirth labors proceeds abnormally. In particular:
Can develop the following consequences of abnormal flow of labor:
If you suspect that preliminary period runs abnormally, you should immediately contact the obstetrician-gynecologist. He should do an external examination. Palpation helps to determine high or low position of the fetus. If the fetus has not dropped, this tells about the presence of pathology of labor. Also about the disease can be judged by the presence of a strong tension in the muscles of the vagina, the immaturity of the uterus for childbirth and spasms.
At the heart of diagnostic pathology preliminary period is the conduct of clinical and laboratory research, allowing to conclude that the reduction acetylcholinesterase activity of erythrocytes, increase in the blood level of the hormones epinephrine and norepinephrine.
It is Possible to conduct an instrumental study. To do this cardiotocography. It is possible to record the strength and duration of contractions.
When the immature cervix and the absence of independent development of labor there is a picture of perenashivanie pregnancy. Therapy will be appointed on the basis of the pathogenesis of the disease. The goal of treatment will accelerate the maturation of the uterus. Can be used, such treatments.
If the patient experienced severe fatigue and increased nervousness, it as treatment prescribed medicated sleep. Also are prescribed sedatives.
The Positive effect of treatment is reflected in the sharp beginning of regular contractions. Or ripening the body for childbirth. When the uterus becomes “Mature”, the SAC is opened and within two hours of the start of regular contractions. If the birth activity does not start, then intravenously administered prostaglandins.
When ineffective treatment along with other complications (obstetric history, the large size of the fetus, breech presentation, OPG-gestosis, the beginning of fetal hypoxia) performed an emergency C-section.
There are two approaches:
Both methods have the goal of fixing labor. Successful outcome was observed in 85% of cases. When choosing a method include the following features pathology:
The approach, which consists in the observance of complete rest pregnant, she administered intramuscularly 0.015 g of morphine. Then called secobarbital inside 0.2 g. This option is quite effective. As a rule, after the injection of morphine the patient falls asleep within the hour. After 4-5 hours of rest, during which the body restores exhausted strength, the woman wakes up without any signs of childbirth or active labor.
If you choose the second path, i.e. the stimulation of oxytocin, you should avoid opening the membranes. Caesarean section is justified only in the most severe cases.
The Main preventive measures to prevent the pathology of the preliminary period are:
A Competent obstetrician should keep monitoring the women who are in the risk group for this pathology. Namely, first-time mothers under the age of 17 years and after 30 years, and women with diseases of some organs (liver, kidney, heart).
So, pathological preliminary period is one of the types of anomalies genericactivities. It occurs quite often. However, thanks to modern medicine 85% timely medical intervention births end happily. Therefore, the appearance of first disease symptoms should immediately contact a competent obstetrician-gynecologist. The anomalous effects of the preliminary period can be very serious, up to fetal hypoxia, the emergence of irregularities in its internal organs, death. Correctly prescribed treatment will help save the lives of both the mother and the child.
