Ultrasonic researches
It is difficult to present modern obstetrics without ultrasonic researches. It and the harmless method, allowing to spend dynamic supervision over a current of pregnancy and a fruit condition. Standard it is considered 3-fold ultrasonic research at normally proceeding pregnancy on terms of 10-12 weeks, 20—22 weeks, 30 32 weeks of pregnancy. However often in addition ultrasonic research spend to the moment of an establishment of pregnancy (on early terms) and at receipt on childbirth (38—39 weeks). During pregnancy it is possible to consider any complications as the additional indication to carrying out of ultrasonic research.
With use gauges ultrasonic researches has considerably raised.
So, egg in a uterus cavity can be seen on term of 2-3 weeks; the little body of an embryo from 4—5 weeks, embryo palpitation is registered from 4—5 weeks; from 7 weeks it is possible to observe separate movements of a fruit; a head as separate formation, it is possible to see from 8 weeks; from 9 weeks it is possible to see legs and embryo handles; in 12 weeks the brain, a backbone, the person, a thorax, a stomach are visible; from 14 weeks brushes and stops, heart, a bladder are clearly visible.
In the first trimester it is possible to establish such pathologies as , absence of an embryo in the egg, the frozen embryo, defects of development of a head, anomaly of finitenesses.
The basic information on revealing of congenital and hereditary diseases of a fruit is given by ultrasonic research in the second trimester of pregnancy in terms from 16 till 28 weeks when all bodies and fruit systems are generated and accessible to detailed research practically.
At ultrasonic researches of a fruit define also its position in a uterus. Usually at pregnancy (in 95—96 %) the kid lays «a head downwards» — head prelying. If till 32 weeks of pregnancy to you make the diagnosis prelying — be not afflicted.
The kid still can change the position till this time.
It will be more difficult to make it if pregnancy is accompanied or .
Definition of a condition of a fruit is very important at pregnancy before sorts. Thus an estimation of rosto-weight parametres , placenta research , (research of movement of blood in vessels of an umbilical cord, a uterus, fruit vessels), diagnostics of abnormal positions of a fruit can be solving at a choice of terms and methods .
At placenta research define its thickness and structure, maturity degree. Degree of a maturity of a placenta is a condition of a placenta, characteristic for this or that term of pregnancy. There are 4 degrees of a maturity of a placenta: About, I, II, III. With each week of pregnancy the placenta grows, its thickness increases for maintenance with all necessary developing kid. By 36-37th week placenta growth stops, the placenta by the pregnancy end starts to "grow old". If degree of a maturity of a placenta advances norm, speak about «placenta presenilation».
