目的:研究B超应用于产科胎儿异常诊断的疗效。方法:对2010—2011年间本院所收治的1000名孕妇进行B超检查,检查时孕妇采取仰卧位,充分暴露腹部,用探头在腹部进行横断、纵断等多角度扫查。结果:经过B超检查,本组1000例孕妇中发现8例畸形胎儿,并且经过分娩或病理检查证实诊断正确。本组胎儿的畸型发生率为0.80%,而相关文献资料记载,畸形胎儿的发生率为0.73%。结论:。由于B超的实施,使得许多畸形胎儿被早期发现并及时将妊娠终止,近些年来,畸形胎儿之中神经管畸形的发生率有所降低,这与孕妇的早期B超检查与筛查有着密切的关系。 Objective: To study the efficacy of B-ultrasound in the diagnosis of obstetric fetus abnormalities. Methods: A total of 1000 pregnant women admitted from 2010 to 2011 in our hospital underwent B-mode ultrasound examination. The pregnant women were supine in the supine position and the abdomen was fully exposed. Transverse, longitudinal and other multi-angle scanning were performed on the abdomen with a probe. Results: After B-ultrasound, in this group of 1000 pregnant women found in 8 cases of fetal malformations, and confirmed by childbirth or pathological examination confirmed. The incidence of malformations in this group of fetuses was 0.80%, while the relevant literature records, the incidence of malformation fetus was 0.73%. in conclusion:. Due to the implementation of B-ultrasound, many abnormal fetuses are found early and terminate the pregnancy in time. In recent years, the incidence of neural tube defects among the deformed fetuses has been reduced, which is closely related to the early B-ultrasound and screening of pregnant women Relationship.
