[The clinical significance of accelerations in intrapartum fetal heart rate monitoring (author's transl)].

Fetuses failing to exhibit accelerations in antepartum fetal heart rate (FHR) testing are considered to be at risk. However, until now the prognostic value of intrapartum FHR-accelerations is not known. The occurrence or absence of accelerations during the last 30 minutes preceding delivery was compared in 812 intrapartum FHR-records with FHR-score (3), umbilical cord artery pH, one and five minute Apgar score values. When accelerations were absent during the last 30 minutes before delivery, severe neonatal depression was observed in 10 per cent of neonates as compared to 5 per cent when accelerations were present. This difference is statistically significant. If accelerations were observed, no correlation was found between rate of FHR increase, amplitude, or duration of accelerations, and fetal or neonatal state.

[Course of twin pregnancies after foetal death in utero (author's transl)].

Premature foetal death in utero of a twin with continued pregnancy and birth after a lapse of at least 12 hours, is a relatively rare occurrence. This was recorded at the University Gynecological Clinic in Basel in 13 women within the last nine and a half years, representing a frequency rate of 0.07% in relation to the total number of births, or 6.8% of all twin births. The special circumstances governing these cases are described and compared with reports published in medical literature on similar cases.

[Twin pregnancy and twin birth, a retrospective (1970-1976) and prospective (1977-1978) study (author's transl)].

Twin pregnancy entails an enhanced hazard especially for the newborn, with regard to both perinatal mortality and neonatal morbidity. The authors deal with the following points in the first part of the article: 1. The classical concepts concerning the distribution of twin pregnancy with regard to enzygotism and dizygotism, and the importance of the modus of placentation. 2. Pathophysiology of twin pregnancy, making three factors responsible for prematurity and hypotrophy of the twins: Lack of sufficient space in the uterus, insufficient uteroplacental exchange and inability of the cardiovascular system to become adapted to the situation. In the second part of the article, conclusions are drawn with regard to the course of pregnancy as well as the twin birth. The main problems listed here emphasise the importance of the following points: -systematic, early ultrasound examination and more frequent controls for keeping a better check on the course of pregnancy and birth, -complete and strict rest in bed around the 31st week of pregnancy to combat prematurity and hypotrophy, -induction of labour before the due date and more liberal application of the indications leading to Caesarian section to combat perinatal mortality and morbidity. Subsequent to the practical application of these conclusions within a prospective study conducted from 1977 to 1978, the authors achieved a mortality decrease from 5.6% to 3.2% (WHO definition).

[Intrapartum fetal heart rate patterns and fetal outcome: prediction of newborn depression (author's transl)].

A statistically significant correlation exists between patterns of fetal heart rate (FHR) and neonatal state. However, the prognostic value of alterations of FHR for the individual has not been established. In 812 deliveries, we analyzed FHR tracings of the 30 minutes preceding delivery and correlated 6 characteristics of baseline, 10 of floating line and 6 of oscillation type with the incidence of severe acidosis (pH of umbilical cord artery less than or equal to 7.10) and low Apgar scores (one minute Apgar score less than or equal to 6). The exact risk for neonatal depression was calculated for each pattern of FHR. A high rate of depressed infants could be expected when the following alterations of FHR were seen during the last 30 minutes before delivery:--mild tachycardia, severe bradycardia,--severe variable decelerations, uniform late decelerations,--oscillation frequency less than 2 per minute independent of oscillation amplitude.

Significance of oscillation frequency in intrapartum fetal monitoring.

Until now, no statistical data have been available on the significance of the frequency of FHR oscillations. In order to evaluate the relation between oscillation frequency and neonatal outcome, the last 30 minutes of 812 FHR records were analyzed with respect to the number of 812 FHR records were analyzed with respect to the number of oscillations per minute only. Close correlations were found between slow oscillations below 2 per minute and the arterial cord pH as well as the Apgar scores after 1 and 5 minutes, respectively. No relation could be established between any oscillation frequency above 2 per minute and the measures of the neonatal outcome. In discussing the results, slow oscillations are suggested to be identical with the sinusoidal FHR. Emphasis is made that for an appropriate pattern recognition, true beat-to-beat recording is required, avoiding any averaging procedure.
