Sift and check 6 kinds of methods of the odd-shaped foetus'
Foetus have four the intersection of situation and purpose examined to produce lie in, understand foetus to be healthy unusually, and do most appropriate handling while finding foetuses unusual, if because the reason of the mother's body causes foetuses to be unusual, if pregnant hypertension may result in growing slowly, will adjust the health status of the parent, let the baby's growth step have the normal track, but some inborn abnormal state is and unable to improve via adjusting parent's state. Can divide into the intersection of chromosome and unusual, gene unusually by inborn unusual part by foetus, structure foetus that unusual other other factor cause unusual. What is among them knows very well for most everybody Tang's, it is the chromosome that becomes abnormal, in addition sex chromosome abnormal condition that appear often too, but gene have the intersection of broad bean and disease, hemophilia while being common unusually. Structural to mean structure that can see unusual at the appearance, as if umbilicus expand, appear and harelip or four limbs imperfect, etc while being unusual, usually structural and unusual will amalgamate abnormal state with chromosome and gene, so, it is unusual that the doctor will follow the constitutive property observed sometimes, to infer the chromosome unusual disease that there may be. It is a pregnant woman of the first child over 34 that unusual tall dangerous group the foetus happens, because women become pregnant after being over 34, relatively high that the chromosome is transferred to the probability in the location while inseminating, therefore promoted foetus' unusual probability, in addition, had once had persons who had miscarried of foetuses unusually and repeatedly who have all been foetus unusual high dangerous group in the past. According to statistics, there is half in the abortive case perhaps because the chromosome is unusual, this has revealed" the thing competes it is selected, the survival of the fittest " Reason. Tang's' disease sifts for the first pregnancy period and carries on time: 11- Carry on the way in 13 weeks The sieve of Tang's' disease is examined and can be divided into pregnant early and pregnant middle period. Pregnant and early Tang's sifts and examines examining for shank thickness and pregnant woman serum of transparent stripe. The shank transparent stripe refers to skin of rear of foetus' shank and makes the space of the water accumulation, while scanning the ultra sound wave, the doctor will measure the space thickness between skin and tissue in detail, the unusual foetus of chromosome, its transparent stripe of shank will be obviously increased thick, especially Tang's' disease. Usually Tang's' disease is more incident on lying-in woman of advanced age, the medical literature has already verified the shank transparent stripe has been the thicker after the foetus, the higher unusual probability of the chromosome is. The pregnant woman examines serum analyze two kinds of biochemical serum, including " dissociating gonad hormone of human fine hair " With " pregnant plasma protein - A " ,Will count together pregnant woman's age and these two kinds of biochemical serum examining value and thickness of transparent stripe of foetus' shank, estimate the unusual risk of chromosome, if its probability of risk is higher than 1/270 after estimation, called high dangerous group, ones that propose further doing attacking are checked in order to confirm. Inspection of person who attack divide, puncture skill or go on the traditional amnion puncture skill on pregnant middle period for pregnant early early amnion. Can obtain the report after sifting the result examined for about 3 days in early days if pregnant. It is up to 70- 80% to detect the examining rate Expert say, it exceeds whom 100,000 pregnant womans participates in to be prospective to step international joint study, plan, reveal by report in one, pregnant in initial stage the ultra sound wave sifts and examines Tang's' disease (namely foetus' shank transparent stripe) Can be up to detecting the examining rate of 70- 80%, compared with only in accordance with detecting the examining rate or sifting 55- 65% examined and detecting the examining rate only with mother's blood of 20- 30% of mother's age, obviously increase and sift the accuracy examined. Measure foetus generally shank time of transparent stripe about 15 minute, but posture of foetus may not be certain while being improper measurement receive sometimes, it is just thickness of the accuracy that energy gets that must be careful to wait for. The test of funicular blood carries on time: Carry on the way before production in 20 weeks The intersection of foetus and except be able to go on, store when born in, in the pregnant course even can go on the funicular blood examine funicular blood. The inspection of belonging to and attacking the test of funicular blood, mainly guide via the ultra sound wave, via the pregnant woman's belly, the funicular blood which collects the foetus is for test. Such situations as chromosome, gene, biochemical function, ferroheme, blood coagulation function, oxygen deficiency state and virus that the foetus' funicular blood can check the foetus are infected. Though its accuracy is extremely high, can get the detailed survey report in 2 days, but it is that the umbilical cord invading the foetus to carry out the way directly collects the funicular blood, so the risk is extremely high. It is less likely to use that foetus' funicular blood is examined, if not urgency, seldom propose carrying on this test. Foetus' ultra sound wave carries on time: Carry on the way in the whole pregnancy period: Foetus' ultra sound wave is the test way that everybody knows very well, belong to the inspection of not attacking. Foetus' ultra sound wave can observe foetus' external structure, so mainly in order to check it is unusual whether the foetus has some constitutive property, the constitutive property that may be found unusually includes: Lip jaw split and spine expand, appear and the intersection of belly and wall split, either it is imperfect for trick to mean, if it is structural and unusual to find, will be according to unusually inferring the gene or chromosome that may have lack the part. Check not 100% accurately in ultra sound wave To it checks to be to come, conduct by water and other soft tissue, can't cross bone or separation of air ultra sound wave, so, it will still receive a lot of restrictions to check, if mother's belly adipose tissue is too thick, foetus' posture is unable to see some organs, may all cause unable interpretation. And the accuracy that will influence the ultra sound wave to check sort of of the amniotic fluid, if there is too much amniotic fluid may cause the image to be unclear, the amniotic fluid may at least hinder the sound wave from entering to pass, so, it has its error values that exists to examine that the ultra sound wave is sifted. Checking the report and can only be interpreted as " the unusual state of any foetus that indeed not sift detection while counting this week " of ultra sound wave ,Some unusual foetus might in can appear count or even born, big week, as if inborn the horizontal diaphragm defect, the urethra is played and split, have no anus disease etc., so, the ultra sound wave is not 100% of the accuracy. And can only watch the appearance in ultra sound wave, so is unable to diagnose with the ultra sound wave about foetus' IQ, eyesight, hearing,etc..
