Predictive value of antepartum non-stress test in multiple pregnancies.

Twenty-seven sets of twins in the last trimester of pregnancy underwent 122 antepartum non-stress tests (NST). The NSTs were evaluated by a cardiotocography score. The last test was performed less than one week antepartum. Fifty fetuses had a normal NST, 13 were small-for-gestational age, but only one of these required intensive neonatal care. Four fetuses had one or more pathological NSTs; all 4 were SGA, and these required intensive neonatal care. The pathological variables in the cardiotocograms were reduced variability, absence of spontaneous accelerations, and (late) decelerations. There was no perinatal mortality. Pathological NST was associated with a statistically significantly increased rate of neonatal morbidity, reduced intra-uterine growth and a low one minute Apgar score. For the evaluation of retarded intra-uterine growth, the predictive value of a normal NST was 95.7%, and the predictive value of a pathological NST was 75.0%. The assessment of fetal wellbeing in multiple pregnancy by non-stressed antepartum cardiotocography is of clinical value and seems to be a better predictor of perinatal morbidity than are serial estriol analyses and serial biparietal diameter measurements.

Predictive value of a single unstressed antepartum cardiotocogram in apparently uncomplicated pregnancy. Introduction of a new cardiotocography score.

Antepartum CTGs were recorded in 88 pregnant women in the 36th week of pregnancy, approximately. The CTGs were evaluated according to three different CTG scoring systems. A new CTG score in now presented. The three systems are compared according to their ability to predict retarded intra-uterine growth. Nine infants were born small-for-date; 8 of these had suspect CTG. In 7 of these cases reduced variability was present for more than 25% of the registration time. When variability is reduced for more than 25% of the registration time there is a statistically significantly higher rate of infants born small-for-date (p less than 0.001). Fifty per cent of those fetuses that did no move spontaneously during registration were born small-for-date. When accelerations were present, 94% of the infants were born normal-for-date. Low estriol and/or low hPL levels were found in 5 of 9 cases where the infants were born small-for-date. Low estriol/hPL and/or suspect CTG were found in all cases of infants born small-for-date. When estriol, hPL and CTG were normal, no infants were born small-for-date.

Significance of unstressed antepartum cardiotocography performed weekly in last trimester of apparently normal pregnancy.

Antepartum Cardiotocographs (CTGs) were obtained at weekly intervals from 28th-30th week of pregnancy onwards in 111 apparently normal pregnancies. A new CTG score was used to assess the 1196 CTGs obtained, 80 per cent of which proved normal. Minor pathology was seen in 19.1 per cent, while moderate or severe pathology was seen in only 0.9% of the CTGs. Of 16 babies born small-for-date, 15 had a pathological CTG on one or more occasions. There was a significantly greater incidence of small-for-date infants when two or more pathological CTGs were observed. Nineteen of 20 women whose babies developed late decelerations during labor had at least one pathological CTG. All infants with an Apgar score less than 5 and all acidemic fetuses had one or more pathological CTGs. All women who required cesarean section because of fetal distress during labor had pathological CTGs on two or more occasions. All cases in which accelerations of the fetal heart rate did not accompany movements (AFM) after the 36th week of pregnancy resulted in the birth of a small-for-date infant, while sporadic absence of AFM before the 36th week was of no importance.
