Abstract:
Objective To investigate the relativity for weight of macrosomia predicted by ultrasound and clinical measurements . Methods 1 037 subjects who were delivered in May to November 2012 ,in Chongqing Health Center for Women and Children ,were collected and analyzed satistically .The parameters for the comparisons included maternal abdominal circumference (MAC) ,fundal height(FH) ,and fetal diameters measured by ultrasonic imaging such as biparietal diameter (BPD) ,head circumference(HC) ,femur length(FL) ,and abdominal circumference(AC) .The coincidence was calculated with real weights and compared with clinical predic-tions .Results When FH+ MAC 134 cm ,the accuracy of preliminary screening for macrosomia is the highest ,the area under the ROC curve is 0 .895 .Combining with the abdominal circumference(AC) by prenatal ultrasound ,the highest prediction rate of mac-rosomia is 75 .2% .when Fetal AC≥37 cm ,macrosomia incidence rate took 91 .7% .Conclusion Pregnant women with FH+MAC<134 cm ,whose incidence of Macrosomia is low .While if the FH+MAC≥134 cm ,combining with the prenatal ultrasound whose fetal AC>36 cm ,especially ≥37 cm ,the possibility of macrosomia is very high .
