目的分析早孕期超声观察胎儿手部各结构可行性。方法回顾性分析2014年10月至2015年1月南充市中心医院进行超声检查的543例孕妇的临床资料,按照不同孕周分为A组(126例)和B组(417例)。A组:孕11~13+6周(胎儿手252只),B组:孕20~24+6周(胎儿手834只),在超声检查中多切面观察胎儿手部声像,比较两组胎儿手部各超声切面的显示率及每手平均扫查切面数。结果早孕期胎儿手腕姿势和掌骨的显示率与中孕期比较差异无统计学意义(P>0.05);早孕期胎儿手指的显示率高于中孕期,差异有统计学意义(P<0.05);早孕期每手平均扫查切面明显少于中孕期,差异有统计学意义(P<0.05)。结论早孕期对胎儿手部进行观察是可行的,有望提前胎儿手异常检出时间。
Objective To analyze the feasibility of various structures of fetus hands during the first trimester of pregnancy. Methods The clinical data of 543 pregnant women who underwent ultrasonography in Nanchong Central Hospital from October 2014 to January 2015 were retrospectively analyzed. Group A (126 cases) and group B (417 cases) were divided according to different gestational age. Group A: pregnant 11 ~ 13 + 6 weeks (fetal hand 252), Group B: 20 ~ 24 + 6 weeks pregnant (834 fetus hand), ultrasonography in multiple cross-section observation of fetal hand ultrasound, compared two groups Fetal hand ultrasound section of the display rate and the average number of sections per hand scan. Results There was no significant difference between gestational age and metacarpal in fetus in early pregnancy (P> 0.05). The rate of fetal finger in early pregnancy was higher than that in second trimester (P <0.05) The average scan section per hand was significantly less than the second trimester, the difference was statistically significant (P <0.05). Conclusion It is feasible to observe the fetal hand during early pregnancy and it is expected to detect the anomalous time of fetal hand in advance.
