    Does coupling of uterine contractions reflect uterine dysfunction?
    (Health & Medical Publishing Group, 1994) Ferreira, C. J.; Odendaal, H. J.
    In a cohort analytical study 47 primigravidas in spontaneous normal labour at term were divided into two groups depending on the presence or absence of coupled uterine contractions during active labour. During monitoring with a pressure tip intra-uterine catheter, 24 patients developed coupled contractions and 23 had a normal contraction pattern. There were no statisfically significant differences between the two groups with regard to maternal age, gestational age, maternal height, fetal weight, head circumference and pelvic size. Patients who developed coupled contractions had a longer duration of labour, a higher uterine activity integral and an increased incidence of caesarean section for failure to progress. Because coupling of uterine contractions may be indicative of dysfunctional uterine activity, and hence a prolonged first stage of labour, failure to progress during labour in these patients should be interpreted with caution in order to avoid the incorrect diagnosis of cephalopelvic disproportion.

    Intraiiteriene dood tydens monitor van die fetale harttempo
    (Health & Medical Publishing Group, 1980) Odendaal, H. J.
    Stressed and non-stressed antenatal fetal monitoring was carried out 9,520 times in 5,932 high risk-patients. Intrauterine death occurred in 48 patients. In 19 patients the fetus died within 1 week of monitoring but before the onset of labour; the results of monitoring had been normal in 14 of these. Abruptio placentae was the cause of 6 of these deaths. Many of the other causes of intrauterine death were also acute complications such as haemorrhage due to placenta praevia, amniotic fluid infection, and cord prolapse. True false-negative test results were rare, and were seen most often in patients with preeclampsia, diabetes and haemolytic disease. Twin pregnancies also caused a problem, as double recording of the heart rate of the normal fetus could create a false sense of security.

    Intraiiteriene dood tydens monitor van die fetale harttempo
    (HMPG, 1980-05) Odendaal, H. J.
    Although the fetal heart rate was being monitored in 16 378 patients during labour, intra-uterine death occurred in 13 cases (0,08%). These fetuses had birth weights of more than 1 000 g. In one patient monitoring was discontinued long before delivery, and fetal death occurred when a partially dilated cervis prevented quick delivery of the fetus which presented by the breech. In all the remaining patients an abnormal fetal heart rate pattern preceded intra-uterine death. Fetal death was probably unavoidable in 4 patients, even with monitoring. Abnormal fetal heart rate patterns were recorded in 2 of these, but the fetuses were estimated as being too small to be delivered by caesarean section. However, they weighed 1 160 g and 1 120 g. The 3rd patient had severe fetal bradycardia on admission and intra-uterine death occurred soon afterwards. The 4th patient refused caesarean section for a prolapse of the umbilical cord, and a vacuum extraction was attempted when the cervix was not yet fully dilated. Severe variable decelerations occurred in 5 of the 8 patients in whom intra-uterine death could have been avoided. Severe bradycardia was present in 3 patients immediately before fetal death, but it may have been present in more patients because the fetal heart rate was not recorded in all cases until death had occurred.

    Results of the in vitro fertilization programme at Tygerberg Hospital, phases II and III
    (Health & Medical Publishing Group, 1986-03) Kruger, T. F.; Van der Merwe, J. P.; Stander, F. S. H.; Menkveld, R.; Van den Heever, A. D.; Kopper, K.; Odendaal, H. J.; Van Zyl, J. A.; De Villiers, J. N.
    Phases II and III of the human in vitro fertilization programme at Tygerberg Hospital are presented. In phase II, 42 laparoscopies were performed and oocytes were obtained from 76% of the follicles aspirated, but with a fertilization rate of only 37%. The viable pregnancy rate per embryo transfer was 4%. Important changes took place in the programme, which led to a fertilization rate of 77% in phase III. Of the 78 patients subjected to laparoscopy, 65 (83%) reached the embryo transfer stage, resulting in a clinical pregnancy rate per embryo transfer of 23%, and with a 19% pregnancy rate per laparoscopy. The changes, methods and results of phases II and III are discussed.

    Severe fetal tachycardia after administration of hexoprenaline to the mother : a case report
    (Health & Medical Publishing Group, 1991) D'Hooghe, T. M.; Odendaal, H. J.
    A fetus developed extreme supraventricular tachycardia (210/min) after intravenous hexoprenaline 10 μg was administered to the mother for intrapartum fetal distress. Urgent caesarean section resulted in the birth of a male baby with a reduced Apgar score; the infant survived after being ventilated for 24 hours.
