Transplacental passage of ketamine after intravenous administration.

This study was designed to measure how fast and at what concentrations ketamine would enter the foeto-placental circulation, when administered intravenously to 10 healthy mothers immediately before forceps delivery, which was indicated by a delayed second stage of labour. It is shown that ketamine very rapidly passes the placenta, and that ketamine levels in cord blood exceed the levels in the maternal venous blood as early as 1 min 37 s after the injection. The ketamine levels in cord blood reach a maximum in the period 1 min 37 s to 2 min 5 s after the injection. Later they show a tendency to decline. A short-lasting, marked elevation of blood pressure was produced by the ketamine anaesthesia. Two of the newborn showed low Apgar scores at 1 min. In one of them this was probably attributable to the anaesthesia.

Oxytocin infusion during second stage of labour in primiparous women using epidural analgesia: a randomised double blind placebo controlled trial.

OBJECTIVE: To determine whether the high rate of forceps delivery associated with the use of epidural analgesia could be reduced through giving an intravenous infusion of oxytocin during the second stage of labour. DESIGN: A randomised, double blind, placebo controlled trial. SETTING: Delivery suites in three hospitals. SUBJECTS: 226 Primiparous women with adequate epidural analgesia in whom full dilatation of the cervix had been achieved without prior stimulation with oxytocin. INTERVENTION: An infusion of oxytocin or placebo starting at the diagnosis of full cervical dilatation at an initial dose rate of 2 mU/min increasing to a maximum of 16 mU/min. MAIN OUTCOME MEASURES: The outcome of labour was assessed in terms of the duration of the second stage, mode of delivery, fetal condition at birth, postpartum blood loss, and the incidence of perineal trauma. RESULTS: Treatment with oxytocin was associated with a shorter second stage (p = 0.01), a reduction in the number of non-rotational forceps deliveries (p = 0.03), and less perineal trauma (p = 0.03) but was not associated with any reduction in the number of rotational forceps deliveries performed for malposition of the occiput. No adverse effects on fetal condition at birth or in the early puerperium were seen in association with the use of oxytocin. CONCLUSIONS: The use of an oxytocin infusion may reduce the high rate of operative delivery associated with epidural analgesia provided that the fetal occiput is in an anterior position at the onset of the second stage of labour but within the dose range studied does not seem to correct malposition of the fetal occiput.

Controlled comparison of induction versus expectant care for prelabor rupture of the membranes at term.

This randomized clinical trial compared oxytocin induction of labor with expectant care for 48 hours after prelabor rupture of the membranes at term. Women at term with prelabor rupture of the membranes for at least 8 hours were assigned at random to induction with oxytocin or to expectant management for 48 hours followed by induction if necessary. Of 168 eligible women, 123 (73%) agreed to participate. More women in the induction group (23%) than in the expectant group (10%) had operative delivery, either cesarean section or instrumental vaginal delivery. In the induction group 41% received analgesia versus 24% in the expectant group (p < 0.005). There was no difference in the rate of maternal and neonatal infection between groups and sepsis was not observed. The active policy of oxytocin induction exposed the mother to a higher risk of operative delivery and a less comfortable labor than the 48 hours expectant care option.

[Pregnancy and labor in juvenile primigravidae].

A report is given on 100 juvenile primigravidae delivered in the period from 1965 to 1973. Course of pregnancy, delivery, postpartum period, rate of premature infants, and perinatal mortality are evaluated. EPH gestosis was observed in juvenile primigravidae at a rate approximately twice that encountered in the total number of all pregnant women. This group of patients is characteristic in that intensive care for pregnant women is required in both out-patient and in-patient treatment. In addition, intensive care for pregnant women has the target of minimising the increased rate of premature infants and the associated elevated perinatal mortality.

Mode of vaginal delivery and epidural analgesia.

A study was carried out on the mode of vaginal delivery in two large groups of parturients: one group comprised 11,264, of whom 0.1% were given epidural analgesia (1977-78) and the other, 10,650, of whom 50% delivered under epidural blockade (1982-83). When the incidence and reasons for instrumental intervention in these two groups were analyzed, it was found that the rate of instrumental delivery was only 1.3% higher (P less than 0.001) in the latter group, which was mainly due to factors not attributable to the epidural blockade. It may be concluded from this survey that epidural analgesia for labor and delivery does not cause an increase in the rate of instrumental delivery.

[The development of Obstetrics at the 2nd Department of Obstetrics and Gynecology, University of Vienna, Medical School, during the last 20 years (author's transl)].

Including the deliveries in 1956, 1961, 1967, 1970, 1971, 1975, 1976 the development of obstetrics at the 2nd Department of Obstetrics and Gynecology, University of Vienna, Medical School, is shown. The frequency of vaginal operative deliveries was reduced, the indicence of ceasarean sections increased from 1.6 to 6.9%. In premature newborns it was possible to gain a higher birthweight, perinatal and postpartum mortality fell from 4.4 to 2.8% and from 3.3 to 1.5% respectively. The connections between these positive results and the new methods and possibilities introduced at the department are discussed.
