诊断值和怀孕期间B超胎儿畸形的冲击   [CLC] R435.1个文档代码] B [文章编号] 2095-6851(2017)01-0-01   检查胎儿的成长是非常重要的,以减少与我国先天残疾儿童的数量,目前的B超检查是检查使用最广泛的方法之一。B超检查是安全,高效,操作简单,考官不会伤害自己腹中的宝宝,检查所需的低成本优势,检查怀孕期间胎儿的应用非常广泛[1]。作为一种有效的诊断方式,B超具有更准确地确定胎儿发育异常,减少误诊率具有重要意义。对于临床妊娠的B超诊断价值的胎儿畸形的研究,选择1220箱子孕妇在我院B超检查,检查结果进行统计,现报道如下。   1。材料和方法   1.1一般资料。选择2016年3月--2016 2009年11月,B超检查的孕妇在我院1220案件,年?g20-36岁,平均26.9±1.8年岁。这些788箱子产妇初产的432例产妇的。222案件胎龄12-19周,20-27周398案件,369案件28-36周,37-40周231案件。由于超声波检查超声波声波b胎儿造成一定的影响,从而使小于12周的胎龄的妇女为研究对象不影响胎儿的生长。   1.2种方法。用来监测B-麦迪逊测试产生的SA-8000实时彩色多普勒超声波诊断装置中,所述探头频率为3.5-5。为0MHz,检测,检测孕妇躺在床上,开始从胎儿头部检查检测探头,直到羊水和胎盘附着部位,胎儿是否观察到身体的各个器官的生长在正常状态下,即如果任何可疑的情况,有必要再次仔细检查部,其中,从多个角度反复观察部位的发展,由胎儿畸形主治医师准确的分析的最终判断发生在哪里。   1.3个疗效标准。如果胎儿出现兔唇,四肢短,无脑儿,脑积水,先天性心脏疾病和开放性脊柱裂,以确定是否胎儿畸形标准。   1。统计分析。使用SPSS15数据进行了分析。0统计软件采用χ2检验,P相比 <0.05 for a s

tatistically significant difference   2。result   58 cases were detected, the detection rate 4.75%, wherein the gestational age 12-19 weeks 9 patients gestational age 20-27 weeks in 26 cases, 14 cases of gestational age 28-36 weeks, 37-40 weeks gestational age eight cases, no missed cases, gestational age 20-27 weeks more sensitive than other gestational period (P <0.05), the specific data in Table 1。After 58 cases of fetal malformation in 27 cases of cleft lip, short limbs in 11 cases, three cases of children without brain, hydrocephalus, 6 cases of congenital heart disease in 7 cases, 4 cases of open spina bifida, in which 58 cases of pregnant women were communication and consultation stop pregnancy, abortion and check the results after the diagnosis of B-match。   3 Conclusion   Currently the development of clinical diagnosti

c techniques become more mature, there are more advanced ways of diagnosis。Check the fetus during pregnancy villus biopsy puncture a conventional manner, into the fetal blood vessels that sampling inspection or puncture fetal amniotic cells is checked by using genetic methods, generally have higher inspection result reliability, but there are also problems caused by a significant impact on maternal and fetal health [2]。With the development of science and technology, the current B-ultrasound technology is also more and more widely used to diagnose fetal malformation go, you can analyze fetal growth and development in various organs of the body parts of the current stage by B-imaging analysis , to determine whether fetal malformation has a good reference value appears。The trials   Fetal organ development and growth characteristics in different periods are not the same, so the B-test is performed when the need to take into account these differences were observed and analyzed targeted。As in the gestational age less than 12 weeks, the fetus's body is small, each physical organs are not yet fully differentiated, if B-ultrasound at this stage, subject to a number of factors interference, resulting in inaccurate test results, while also the threat of an impact fetal development, it is generally less than 12 weeks gestational age is not recommended maternal B-ultrasound [3]。12-18 weeks, differentiate fetal skull substantially completed at this time can be observed whether the fetus through the B-hydrocephalus, brain child symptoms。20-36 weeks maternal amniotic fluid has been very adequate, range of motion and the time the fetus is also increased, which contributes to the accuracy of detection, improve the detection rate, multi-dimensional image data by detecting B-acquired have been able to fully reflect fetal growth and development conditions at this stage [4]。After 28 weeks, significantly faster growth of the fetus, with a significant increase in volume than before, can be found by detecting whether the B-fetal organs physiological problems, but this time the problem of fetal malformations obviously not observed the probability of missed over the previous gestational age increases, the need to check again in late pregnancy diagnosis。37 weeks after the re-examination is to determine whether the fetus has major deformities。If diagnosed in the early fetal deformities require consultation with women and their families were induced abortions, to prevent the latter causing serious psychological and physical harm。In this experiment, 20-27 weeks gestational maternal fetal malformations detection rate significantly higher than other groups (P <0.05), while 58 cases of fetal malformations in pregnant women were pregnant after stopping communication and consultation, examination results after induction with B ultrasound diagnosis consistent, indicating the accuracy of B-ultrasound。   references   [1] in Dai Qing。B-detecting fetal abnormalities application [J] nuchal translucency thickness screening in early pregnancy。Chinese Journal of Modern Medicine, 2014, 24 (25): 84-86。   [2] Jianjun, Jianghong Fang, Geng Shujun, etc。Trimester ultrasound screening for simple single
