Obstetric management of preterm labour.

In recent years the trends in the obstetric management of preterm labour have moved in the direction of more active policies with greater use of fetal heart monitoring and Caesarean section to avoid traumatic and asphyxial damage to the baby. Conservative management still has an important place, especially in association with extreme prematurity. Following initial enthusiasm, the use of tocolytic drugs and antenatal corticosteroids are going through a phase of re-evaluation and careful assessment is essential in individual cases to avoid their inappropriate use. Future developments in the obstetric management of preterm labour will depend upon careful evaluation studies which examine not only the short-term mortality statistics but also the long-term effects in respect of neurological and developmental handicap. This task is one of the major challenges for obstetricians to tackle over the next two decades.

Risk factor analysis of peri-neonatal mortality in rural Guatemala.

Peri-neonatal mortality is a serious health problem in Guatemala, especially in rural areas where most deliveries occur at home and are overseen by traditional birth attendants (TBAs) who function in the role of midwives. The three aims of the work reported here were to identify important predictors of peri-neonatal mortality within a rural area of Guatemala; to assess the effects of traditional and modern health care providers on such mortality; and to find ways of identifying high-risk women who might benefit from transfer to a hospital or clinic. For these purposes a case-control study was conducted of 120 women in the rural department of Quetzaltenango who had lost their babies from the 20th week of pregnancy through the 28th day of life. These women and 120 controls were interviewed in their homes by trained physicians, using questionnaires in Spanish or the appropriate Indian dialect, and the results were analyzed through a series of statistical tests. It was found that the complications of pregnancy and delivery with the greatest statistical significance were prematurity, malpresentation, and prolonged labor. Population-based attributable risks of these complications demonstrated that they accounted for significant proportions of the observed peri-neonatal mortality. While these conditions cannot be eliminated, within the rural Guatemalan context it appears that early referral of women with these complications to more specialized care settings could result in improved delivery outcomes.

Clinical experience with the Silc Cup Vacuum Extractor.

The relative merits of vacuum extraction have been extensively studied and its advantages analysed. These include its ease of application, encouragement of "autorotation" of the malpositioned foetal head and its safety for both foetus and especially the mother. One hundred and eighty-six vacuum extraction assisted deliveries were performed at the Department of Gynaecological Oncology & Urology, Kandang Kerbau Hospital, from 1988 to 1990 using the 50 mm Silicone Silc Cup Vacuum Extractor (Menox AB). Anaesthetic requirements were minimal with 97% of cases accomplished with local perineal anaesthesia. Maternal complications were very few and only 1.6% of cases had third degree lacerations. There was no maternal or foetal mortality. The most frequent foetal morbidity was neonatal jaundice (28%) with only 7% requiring phototherapy. Cephalohaematoma was found in 8% and 2% had minor scalp abrasions. There were 3 infants with subaponeurotic haematoma who subsequently recovered uneventfully. Vacuum deliveries that were attempted but completed by forceps deliveries ("failed" vacuum extraction) accounted for 10% of total cases. The Silc cup vacuum extractor although not a replacement for all forceps manoeuvres offers a safe and efficient method of assisted delivery under the appropriate clinical circumstances.
