We evaluated the proficiency of obstetrics senior house officers, not formally trained in ultrasonography, in assessing fetal viability, the number of fetuses and gestational age. Of 366 women who had an ultrasound examination at the first antenatal visit, 7 (2.1%) had nonviable pregnancies and 7 pairs of twins were correctly identified. Of these women, 329 had a detailed anomaly scan at 18-20 weeks. No anomalies were detected at either scan. Of the booking scans performed by the senior house officers, 89.4% correctly assessed the gestational age of the pregnancy when compared to the anomaly scan (+/- 1 week). One in 10 of the scans performed by the senior house officers was inaccurate. This is important particularly when being used for risk assessment in serum screening for Down syndrome. At present the early ultrasound scan should be performed by more formally trained personnel.
我们评估了未接受过超声检查正规培训的产科住院医师在评估胎儿生存能力、胎儿数量和孕周方面的熟练程度。在366名首次产前检查时接受超声检查的女性中，7例（2.1%）为不可存活妊娠，7对双胞胎被正确识别。在这些女性中，329例在18至20周时进行了详细的畸形扫描。两次扫描均未检测到异常。与畸形扫描相比（±1周），住院医师进行的预约扫描中有89.4%正确评估了妊娠孕周。住院医师进行的扫描中有十分之一不准确。这一点在用于唐氏综合征血清筛查的风险评估时尤为重要。目前，早期超声扫描应由接受过更正规培训的人员进行。
