Evaluation of symphysis fundus measurements in a large antenatal clinic.
The obstetrical records were reviewed for all patients that had delivered over a 3-month period. From this group of 1455, a sample of 386 was taken that had a singleton pregnancy, had booked before 24 weeks' gestation and had attended the antenatal clinic at least twice. The study group comprised 65 patients with less than expected symphysis fundus growth and a control group of 249 in whom growth seemed adequate. The remaining 72 subjects' files were either incomplete or the interobserver variation of the symphysis fundus measurements at the end of pregnancy seemed too high.
Deficient intra-uterine growth, as shown by the symphysis fundus measurements, was significantly associated with both low birthweight (< 2500 g) (odds ratio 3.02) and intra-uterine growth retardation (IUGR) (odds ratio 3.43), but no association was found with perinatal mortality. The sensitivity for detecting IUGR was 42%.
Symphysis fundus measurements, as made in our antenatal clinic, seem of limited value. We propose that the number of observers be restricted in order to decrease the interobserver variation.
在一家大型产前诊所评估耻骨联合上缘测量值。
回顾了在3个月期间内所有分娩患者的产科记录。在这1455名患者中，选取了386名单胎妊娠、在妊娠24周前登记且至少两次到产前诊所就诊的患者作为样本。研究组包括65名耻骨联合上缘生长低于预期的患者，对照组为249名生长似乎正常的患者。其余72名受试者的档案要么不完整，要么妊娠末期耻骨联合上缘测量值的观察者间差异似乎过大。
耻骨联合上缘测量值显示的宫内生长不足与低出生体重（<2500 g）（比值比3.02）和宫内生长受限（IUGR）（比值比3.43）均显著相关，但与围产儿死亡率无关联。检测IUGR的敏感性为42%。
在我们的产前诊所进行的耻骨联合上缘测量似乎价值有限。我们建议限制观察者数量，以减少观察者间差异。
