Neonatal acid-base balance in spontaneous and instrumental vaginal deliveries.

The acid-base balances of 63 neonates delivered either spontaneously or by the vacuum extractor or low forceps were compared. The outcome was similar in neonates delivered by vacuum extractor or forceps. However, significant differences were noted in the pH and base deficit of infants born by instrumental versus spontaneous delivery. These differences were no longer present when groups with similar duration in the second stage of labor were compared. We conclude that the use of instruments for outlet vaginal delivery carries no additional risk for the fetus.

[Frequency of obstetrical operations and perinatal mortality before and after admission of continuous fetal monitoring (author's transl)].

Two groups of obstetrical patients were statistically analyzed with a computer. The first group A (2339 deliveries, January 1967-June 1968) was controlled by conservative obstetrical methods, the second group B (2512 deliveries, January 1973-June 1974) was controlled by continuous monitoring of fetal heart rate and by analysis of fetal blood during labour. The results of the statistical analysis can be summarized: 1. The frequency of obstetrical operations (vacuum, obstetrical forceps, Caesarean section) increases from 12.8% (group A) to 22.5% (group B). 2. The percentage of Caesarean sections decided on for the sake of the child rose from 45.7% (group A) to 54.7% (group B). 3. Vital indications fell due to increasingly preventive obstetrics from 54.3% to 45.3%. 4. The frequency of Caesarean sections rose due to increasing indication "absolute or relative pelvic disproportion" of the mediterranean patients. 5. However the analysis of fetal blood during labour and the continuous monitoring of fetal heart rate has prevented a further increase of Caesarean sections. 6. The increasing percentage of obstetric forceps was due to our intention of preventing prolonged labour. 7. Maternal mortality after operative delivery reached 0.04% in group A and 0% in group B. 8. Perinatal mortality of children, delivered by operation, has decreased from 3.0% (group A) to 0,7% (group B). 9. The Apgar scores after operative deliveries were much better in group B (continuous fetal monitoring) than in group A (without fetal monitoring).

The elderly primigravida.

A five-year review of 127 elderly patients (35 years of age and over), in their first pregnancies, defines the risk to the fetus in terms of perinatal death and neonatal morbidity. With the equivalent of a perinatal mortality rate of 94/1,000, an 11 per cent incidence of small-for-dates infants, and a neonatal morbidity rate of 18 per cent, there would still appear to be a need for an increased awareness of the fetal risks in this group and an increased emphasia on their prevention. Areas of management in prenatal care and labor which might reduce these figures are defined.

Rupture of membranes before the onset of spontaneous labour increases the likelihood of instrumental delivery.

We studied obstetric outcome in 350 consecutive nulliparous women in spontaneous labour and term pregnancy. Women who presented with rupture of membranes before the onset of contractions were more likely to deliver by forceps compared with those in whom contractions preceded rupture of membranes. This increased likelihood of instrumental delivery was significant with and without the use of extradural analgesia in labour (P less than 0.05 and P less than 0.001, respectively). Furthermore, significantly more women with premature rupture of membranes received extradural analgesia in labour (P less than 0.01). We conclude that any study which aims to examine the influence of extradural analgesia on the outcome of delivery should include premature rupture of membranes as a bias factor.

Compound presentation following external version.

Two cases of compound presentation following external version are presented. The frequent combination of the feet with the vertex following this procedure and its association with a higher fetal mortality, interference rate, and obstructed labour than the hand and vertex combination are highlighted. The aetiology, problems in diagnosis, and management are discussed. Measured to prevent and deal with this complication are suggested.

Lumbar epidural analgesia in labour: relation to fetal malposition and instrumental delivery.

The incidence of instrumental delivery and malposition immediately before delivery was compared in patients who were given lumbar epidural analgesia and those who were not. Instrumental delivery was five times more common and a malposition of the fetal head was more than three times as common in the epidural group as in women who did not receive regional analgesia. Similar incidences were found even when the epidural was electively chosen before labour in the absence of medical indications. The instrumental delivery rate was affected by parity, the length of the second stage of labour, and the return of sensation by the second stage but not by other factors studied. The high incidence (20%) of malposition associated with epidural analgesia was not affected by any of the factors studied. The psychological and physical disadvantages of malposition and instrumental delivery have yet to be assessed. In the meantime, when there are no medical indications for epidural analgesia, the advantages of pain relief should be weighed against those of a normal spontaneous delivery.

Community obstetrics in an urban situation.

The majority of the world's population is of poor economic status, and this is commonly associated with high fertility levels and high infant mortality and morbidity. This population can be divided into two main groups: those in over-populated urban areas and those in scattered rural areas. Both groups have their peculiar problems and comprehensive maternal and child health is a formidable task. This paper is an account of the obstetric services in an urban population in the municipality of Salisbury, Rhodesia, where there is close co-operation between hospital and municipal authorities and all high-risk maternity patients are delivered in hospital and low-risk ones in municipal maternity units. Methods of selection of patients and results obtained are shown.
