Pregnant woman needs 5-7 in pregnancy commonly second supersonic examination, more perhaps.
The examination with have 3 times important is indispensable:
11-13 week + NT of 6 days of early pregnancy and the sieve with fetal and serious unbalanced structure are checked.
Systematic sieve checks 18-24 Zhou Zhongyun, it is systematization of fetal whole body discharges abnormal examination.
29-32 week late pregnant is fetal grow development evaluates sexual examination, hold compensatory sex concurrently to discharge abnormal to check a function.
The frequency of supersonic examination, the need with main obstetric and clinical basis increases with the demand of fetal disease state.
2, is antenatal supersonic check can does check give all and fetal deformation?This is the error of sex of a common sense, pregnancy is supersonic the examination is impossible that check gives all and fetal deformation, some deformation also are not single censoring can discover, need dynamic observation, say antenatal is supersonic so platoon abnormal is not all-purpose.
The reason has the following sides: ① antenatal is supersonic the effect that suffers a variety of elements, be like fetal quantity of the position inside palace, pose, amniotic fluid, pregnant woman is fat equipment of ply, examination, the interference of different level is become like quality, reduce the accuracy of the examination. ② supersonic examination basically is aimed at structural sex disease, cannot be forecasted to functional sex disease and judge. Disease of ③ part structure is dynamic development process, not be single censoring can discover, the likelihood needs for many times to check. For example: Pregnant is terminal appear " double bubble is asked for " , block of ability clew duodenum, early in pregnant examination is normal; Partial midriff hernia just has show to late pregnancy; Still have pathological change of congenital heart valve, stricture or the process that closedown may be an advance gradually are spent again in developing. The experience of ④ examination doctor and the recognition level to the disease.Say so, doing know the inside story of the countersign when systematic sieve is checked or fetal heart is checked to agree with a book, should inform pregnant woman and family member antenatal namely supersonic impossible check gives all and fetal deformation, but the working principle of supersonic doctor is as far as possible the visible deformation that goes discovering existence.
3, are 4 dimension supersonic be antenatal supersonic the superlative degree or the most advanced examination?This is a serious commonsensible sex error! Because 4 dimension are supersonic not more supersonic than 2 dimension more advanced, or more be helpful for abnormal examination, its are the biggest the advantage is to let do not know supersonic pregnant woman and family member to understand supersonic.
What is 4 dimension supersonic?
Collect 2 dimension tangent plane to undertake the computer rebuilds continuously, form three-dimensional and stereo into picture, dynamic and three-dimensional it is 4 dimension, saying 2 dimension are supersonic so is a foundation, 2 dimension graph is clear, 4 dimension ability is clear. 2 dimension are supersonic it is to exceed unripe doctor to discharge abnormal to check commonly used technology and main measure, even if is to make 4 dimension supersonic, the time of 95% is to seeing 2 dimension, say supersonic examination basically relies on 2 dimension so, 4 dimension are supersonic be assist or complement, can let exterior deformation be clear at a glance, let do not know supersonic person to also can be understood supersonic. Another action of 4 dimension kisses namely child ligament, accurate mom and accurate father see the hand of the appearance of darling, darling and foot for the first time, should have how gratified.
In view of policy of Yo of our country prepotent actor, discover serious deformation is fetal, can change gravid outcome.
For example: To the serious deformation of fetal structure, after be born cannot Jiao Zhi's deformation, include 6 big deformation, can choose induced labor, but the inspection that requires hospital of two 3 armour confirms as a result; If serious transmissibility disease is 3 body of 3 body of 3 body of 21- , 18- , 13- , special syndrome of accept family name; If single gene hereditary disease is DMD, hemophiliac, can stop gravid. Option reachs a household in pregnant woman.
Do not suggest pregnant woman and family are a few righter do not affect live quality or the blemish that after be born, can effect a radical cure completely, make extreme choice. We should respect life.
