head circumference
1.The position of conus medullaris terminal had a negative correlation with gestational age,body weight,head circumference and body height.
2.Methods: (1) Study the relationship between ultrasonic measurement of the fetal biparietal diameter (BPD), head circumference (HC), femur length(FL), abdominal circumference(AC) and neonatal birth weight in 280 cases.
3.They received ultrasound scan at about 28th weeks and 38th weeks to measure fetal head circumference(HC),abdomen circumference(AC),femoral bone,humeral bone length(FL,HL)and biparietal diameter(BPD).
4.Methods One hundred and eighty four pregnant women whose sum of the fundus height plus abdominal circumference was more than one hundred and forty were chosen,the biparietal diameter (BPD),abdominal circumference(AC), femoral length(FL),head circumference(HC) of these fetuses were measured with ul trasound;
5.Methods Fetal biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and fetal thigh soft tissue thickness (FTSTT) were measured by ultrasonography and analyzed with neonatal birth weight in 178 cases.
6.Methods Fetal biparietal diameter(BPD),head circumference(HC),abdominal circumference(AC),femur length(FL),fetal liver length(FLL) and fetal liver area(FLA) were measured by ultrasonography and analyzed with neonatal birth weight in 160 cases.
7.Methods: Fetal biparietal diameter(BPD), head circumference(HC), abdominal circumference(AC), femur length(FL), fetal thigh soft tissue thickness(FTSTT), fetal liver length(FLL) and fetal liver area(FLA) were measured by ultrasonography and analyzed with neonatal birth weight in 360 cases.
8.Methods:Biparietal diameter(BPD),head circumference(HC),abdominal circumference(AC),femur length(FL),liver length(LL),and femur soft tissue thickness in 400 fetuses were measured with B ultrasound,and the relationship between these data and baby birth weight was analyzed.
9.Methods Five body indices of a total of 1 757 AGA neonates converged from 12 cities in China were caculated with computer,which were the gestational maturation,the Quetelet Index(QI),Rohrer Index (RI),Recumbent length Croun Rump length Index(BRI),Recumbent length/Head circumference(BL/HC),Mid-Arm circumference/Head circumference(MAC/HC) ration; and the relative longitudinal regularity,variation,percentile of each index.
10.Birth weight,head circumference,birth length and 1 min Apgar score in offspring from intervention group were statistically higher than that of control group(P<0.01).
