Poor fetal growth is an important cause of perinatal mortality and morbidity. Based on the hypothesis that early diagnosis of fetal growth problems leads to more appropriate management and therefore, improved outcome, a randomized controlled trial of ultrasound measurement was performed on 1,528 women booked through a hospital antenatal clinic. This compared a number of perinatal outcomes between the group who had a routine 2-stage examination (early dating and 34-week scan) and a group who had only a dating scan and then additional scans as generated by their clinical situations. No significant differences could be found between the groups when these perinatal outcomes were considered. These results mirror previously published randomized controlled trials. Selection of women for third trimester ultrasound examination for suspected fetal growth problems should be based on careful clinical assessment and should not be routine.
胎儿生长发育不良是围产期死亡率和发病率的重要原因。基于胎儿生长问题早期诊断可带来更恰当的管理从而改善结局这一假设，对通过医院产前诊所登记建档的1528名女性进行了一项超声测量的随机对照试验。该试验比较了接受常规两阶段检查（早期预产期确定和34周超声检查）的组与仅进行预产期确定超声检查然后根据临床情况进行额外超声检查的组之间的一些围产期结局。当考虑这些围产期结局时，两组之间未发现显著差异。这些结果与之前发表的随机对照试验结果一致。对于疑似胎儿生长问题而选择在孕晚期进行超声检查的女性，应基于仔细的临床评估，而不应作为常规检查。
