ABSTRACT

SUMMARY Normal foetal heart rate (FHR) values were obtai- ned from a sample of patients with no pathology. There were 20 patients with normal laboratory analy- sis. Pregnancy age ranged from 27 to 39 weeks, with a mean and standard deviation of 33.25 #+ 3.11 we- eks. Uterine contractility and FHR registers were made

    ABSTRACT: Fetal heart rate (FHR) values and accelerations were determined in fetuses with restricted growth and development and were compared with those in a control group. The study design was open, prospective, comparative and exploratory.The sample consisted of 40 patients divided into two groups. Group 1 (problem group) was composed of 20 pregnant women diagnosed with restricted fetal growth and development. Group 2 (control group) consisted of 20 patients with normal pregnancies.Ultrasound was used to determine the biparietal diameter of the fetuses. FHR and uterine contractility were measured. The Apgar test was used to evaluate neonatal status. Neonates were weighed and measured.Basal FHR in group 1 was 5 beats higher with an amplitude of 3 beats less than in the control group. These differences were highly significant.Dispersion diagrams were drawn and linear regression was calculated for the parietal diameters of fetuses with restricted growth. The equation was y=0.547x+64.38 and the correlation coefficient was R2=0.3561. In the control group the equation for the linear regression was y=2.0344x+12.944 and the correlation coefficient was R2=0.9981.The means of the biparietal diameters of groups 1 and 2 were compared but no significant differences were found. The mean values for uterine height and abdominal perimeter for the two groups were 33.45cm and 101.15cm, respectively.The physical status of the newborns was evaluated using the Apgar test. At 1min, two neonates were depressed with an Apgar score of 6. Twelve neonates were vigorous with scores ranging from 7 to 9 and the six remaining neonates were not tested. At 5min, scores ranged from 7 to 9.When the two groups of neonates were compared, the weights and heights of those in group 1 were 243g and 2cm lower and these differences were significant (p

    ABSTRACT: Basal values of fetal heart rate (FHR) and amplitude of the accelerations were determined in patients with prolonged pregnancy and were compared with those in a control group. The study design was open, prospective, comparative and exploratory.The sample consisted of 40 patients divided into two groups. Group 1 (problem group) was composed of 20 patients with prolonged pregnancies. Group 2 (control group) consisted of 20 patients with a normal pregnancy.Ultrasound was used to determine parietal diameter. FHR and uterine contractility were measured for 2 h.Basal FHR and the amplitude of the accelerations in the two groups were compared. In group1, FHR was 3 beats higher and the difference between the means was highly significant. The difference in amplitude was not significant.In two FHR recordings, Type II Dips of moderate amplitude were registered during a reactive pattern.Dispersion diagrams were drawn and the linear regression of the biparietal diameter values of group 1 fetuses was calculated. The equation was y=2.2183x + 7.6909 and the correlation coefficient was R2=0.8877. In group 2 (normal distribution) the linear regression equation was y=2.0344x + 12.944. The correlation coefficient was R2=0.9981.The means of the biparietal diameters of the two groups were also compared but no significant differences were found. The mean values for uterine height and abdominal perimeter were 37.15cm. and 109.10cm, respectively.The physical status of the newborns was evaluated using the Apgar test at 1 and 5 minutes. Three children were born depressed with a score of 2. Three other children were not tested. Fourteen showed a score in the range of 7–8. At 5min their score was 9. Two neonates remained depressed.The weights of the neonates in the two groups were compared and those in group 1 were 418g heavier. The difference between mean weights was significant. Height was not significantly different.
