[Results of ultrasound brain studies in clinically normal newborn infants].

Ultrasound investigations demonstrating intracranial hemorrhages (periventricular intraventricular hemorrhage-PVH/IHV) were performed in 401 term newborns. Without consideration the mode of delivery incidence of intracranial hemorrhage was 4.7%. There were only subependymal hemorrhages grade 1 and 2. In case of vaginal-operative delivered children frequency of hemorrhage in forceps delivered babies was really lower than in vacuum extracted newborns.

Recent changes in birth attendant, place of birth, and the use of obstetric interventions, United States, 1989-1997.

Although more than nine out of every ten births are attended by physicians, the percent of births attended by midwives increased during the 1989 to 1997 period and accounted for 7% of all births in 1997. About 99% of births in 1997 were in hospitals, basically unchanged from 1989, but the percent of out-of-hospital births that occurred in residences increased over the period, while those in freestanding birthing centers declined. The percent of mothers receiving electronic fetal monitoring, ultrasound, and induction and stimulation of labor increased. The most dramatic increase was a doubling of the use of induction. In 1997, approximately 18% of all births were induced. Midwives as well as physicians increased the use of these obstetric procedures over the 1989 to 1997 period, and the use of many procedures by CNMs was as high, or nearly as high, as use by physicians. The rate of cesarean births dropped by 9%, from about 23% in 1989 to about 21% in 1997, while the rate of vaginal birth after a previous cesarean increased by 50%. The proportion of births assisted by forceps consistently declined during the period, while the use of vacuum extraction consistently increased. The number of episiotomies performed in the United States declined each year during the 1990-1996 period.

[Obstetric spoons (author's transl)].

The article describes "obstetric spoons" which are easy to apply and which can be used as well as the forceps and the vacuum extractor for vaginal-operative termination of labor. These spoons offer the following advantages: They are an effective and relatively harmless instrument which can be applied rapidly and easily even by those who are less skilled. During extraction, the spoons are only slightly pressed onto the head of the child by the operator's hands; the additional pressure required is exercised by the soft parts of the mother. It is hardly critical if the spoons are not applied exactly in transverse diameter. If the traction force applied is too strong, they separate and slide over the head without exercising any further pressure. This counteracts any possible overforceful extraction. The spoons can also be applied simultaneously in combination with vacuum extraction and girdle expression, which renders even complicated vaginal surgical procedures from the mid-pelvic plane relatively harmless with regard to the strain exercised on the child.

Trends in labour and birth interventions among low-risk women in New South Wales.

OBJECTIVE: To examine recent trends in obstetric intervention rates among women at low-risk of poor pregnancy outcome. DESIGN: Cross-sectional analytic study SETTING AND POPULATION: A population of 336,189 women categorised as low-risk of a poor pregnancy outcome who gave birth to a live singleton in NSW from 1 January 1990 to 31 December 1997. MAIN OUTCOME MEASURES: Obstetric intervention rates including oxytocin induction and augmentation of labour, epidural analgesia, instrumental births, caesarean section and episiotomy METHODS: Trends over time were assessed by fitting trend-lines to numbers of births or by trends in proportions. Unconditional logistic regression was used to assess the impact of epidural analgesia on instrumental birth over time. RESULTS: Rates of operative births did not rise despite increases in maternal age and use of epidural analgesia. Instrumental births declined over time from 26% to 22% among primiparas and 5% to 4% among multiparas. There was also a shift to vacuum extraction rather than forceps. Although instrumental birth was strongly associated with epidural analgesia, the strength of the association declined over the study period, for primiparas from an adjusted odds ratio of 7.2 to 5.2 and for multiparas from 13.2 to 10.3. CONCLUSIONS: Increased use of epidural analgesia for labour has been a feature of the management of birth at term during the 1990s. The decline in the strength of association between epidural analgesia and instrumental birth may reflect improved epidural techniques and management of epidural labour, and recognition of the adverse maternal outcomes associated with forceps and vacuum births.
