660 times of measurement of biparietal diameter in combining with analytical computer were performed on 74 female subjects of 16-42 week age of pregnancy (9 times for each subjects) to determine the fetal age. Results showed a close relation of biparietal diameter and fetus age. The speed of growth of biparietal diameter was high initially then lower gradually, with the age of 16-30 weeks, BD grown up 3 mm each week, and with the age of 31-37 weeks: 2 mm and 38-40 weeks: 1 mm

192 pregnancy were hospitalized to monitor post-term infant with fetal age over 42 weeks and fetal condition suffered from Clifford syndrome. The results showed that: fluid index examination by ultrasound are selective method to diagnose fetal suffered from early Clifford syndrome. The cut-off value of 40 mm amniotic fluid index is considered as a Clifford’s syndrome marker. This is a good method of choice for monitoring the postterm infant

On 850 subjects, study was carried out on the correlation between the length of humerus and of femur (H/F) corresponding to the fetal age from 14 to 30 weeks. Results showed the reduction of H/F length ratio along the age because that the femur growth more quickly than the humerus. The ratio reduced from 0,99 in 19th week to 0,87 in 30th week. This correlation is very useful for antenatal diagnosis

Fundal height and abdominal circumference has been used for predicting fetal weight by many obstetricians for a long time. The results has proved: there are relatively relationship between, measurement values and fetal weight with the correlation coefficient (r=0.7). The error prediction was high, due to the misleading factor: abdominal thickness. This is differ from mother to others. This should be eliminated by using the actual uterine height (AUH) and actual uterine circumference (AUC) value. The results of this study demonstrated that: a close correlation between AUH (x1); AUC (x2); AUH+AUC (x3) and fetal weight (y) with correlation function and correlation coefficient as follow: Y=206.8x1-311.2; r>0.9; Y=79x2-3369.9; r>0.9; Y=57.6x3-3348; r>0.9; This appear to be a higher accurate method in fetal weight assessment.

74 pregnancies in National Institute of protection of Mother and Children’s Health were studied concerning the fetal weigh matching 8 parameters of ultrasonic measurement of the fetus. Data based on the ratio of weigh/height of each method were annalyzed. The ratio of the mean diameter of fetus abdomen and the weight is r # 0,8 give a high value of diagnosis with an error <200g (55%). This is an eligible and generally applicable method. The graphic of abdomen development showing the correlation of mean diameter of the fetus and the fetal weight has clinical application value for diagnosis

Fetal femur length/biparietal diamater ratio (FL/BPD) assessement with the use of ultrasonic fetal biometry on 875 selected normally gravids from 14 to 30 weeks in a carefully designed cross sectional study have given the results: A good correlation between this ratio and gestational age, with correlation coefficient r = 0.87, was found. The fitted correlation function: y = 0.0454 x + 0.2992, where y = FL/BPD x = gestational age. The mean and centile 5, 10, 50, 90, 95 values of FL/BPD obtained in this study should be considered as a based prediction for normal, and abnormal development of the fetus

Study on the correlation between the femur length and gestational age from 14-30 weeks. Determination of numeric value table of femur length in correlation with centesimal line 5, 10, 50, 90 and 95 to make a basis to built fetus’s femur length chart, applying to monitor normal or malformation status of fetus. The results: fetus’femur length have a closely correlation with gestational age belong to a second-class function: y = 0.0019x2 +0.2377x + 11.1892, r = 0.97, in which, x = gestational age, y = femur length. Based on this chart, the accuracy of the dating random error about 1 week. The earlier, the estimation of gestational age, the more accurate

816 cases of ectopic pregnancy in the Institute of Protection of Mother and Newborn from Jan 1999 to Dec 2002 were operated. Among them, 49% had a history of artificial abortion. Apart from other related factors such as the age, the frequency of delivery, gynecoobstetrical history, functional signs such as vaginal bleeding, which have suggesting value of ectopic pregnancy, the most indicating signs were abdomen pain and delayed menstrualation. 97% males are located in uterus neck duct. The rate of endoscopic surgery and the rate of conserved salpingo-uterine surgery were low

The biparietal diameters (BPD) chart may not be used universally to define pregnancy date. The results of this study proved obviously that the prediction of gestational age (GA) by using the BPD chart 1 (Vietnam) and BPD chart 2 (Europe) are significantly different: Approximately acurate prediction < 7 days: 75.2% (chart 1) and 20.8% (chart 2); Pregnancy dating error > 7 days: 16.8% (chart 1) and 79.2% (chart 2); Maximum error: 16 days (chart 1) and 28 days (chart 2); GA prediction lower than actual GA: 36% (chart 1) and 95.2% (chart 2). Chart 2 is less accurate than chart 1 as a predictor of gestational age in Vietnam

Low birth weight (under 2,800g) has been shown to be related to poor infant outcome both in terms of elevated mortality and morbidity. Early indentification of low birth weigh infants by mean of using the rule to measure chest and arm circumference at the time of infant discharge from the community health service or at home may enable limited the risk of new born. This can be determine, since arms, chest circumference has a good correlation with birth weight. The cut – off point of = 9cm in arm circumference and = 29cm in chest circumference was being used as a predictor of high risk in infant with low birth weight under 2,800g
