Oxytocin use in South Africa--a review.

OBJECTIVE: Oxytocin is one of the most frequently used drugs in labour and there are many different dosage regimens. The aim of this study was to examine the use of oxytocin by obstetricians in South Africa. METHODS: A specially designed questionnaire was drawn up and distributed to specialists according to an address list obtained from the South African Society of Obstetricians and Gynaecologists. RESULTS: Three hundred and fifty questionnaires were distributed, with 174 processed for analysis. The majority of obstetricians (70.3%) reported that they would not use oxytocin for induction of labour in a patient with a previous lower-segment caesarean section, and 63.7% said that they would not consider the use of oxytocin in a patient with a multifetal pregnancy. Most respondents used oxytocin for induction of labour in multigravid patients and 91.9% also used oxytocin for augmentation in these patients. However, clinicians would not use oxytocin if the patient was a grand multipara. CONCLUSIONS: Most clinicians adhere to accepted protocols practised internationally, with a few exceptions. The use of oxytocin for both induction and augmentation of labour in women with one previous caesarean section is not practised in South Africa, despite evidence suggesting its safety.

Cystic adenomatoid malformation of the lung: neonatal management of 21 cases.

Currently, congenital cystic adenomatoid malformation of the lung (CCAM) is often diagnosed antenatally by ultrasound, allowing prompt and appropriate medical and surgical management after birth. The authors report 21 cases of CCAM admitted from 1988 to 1997 to a neonatal intensive care unit and treated by high-frequency oscillation (HFO) and early surgery. Six infants developed respiratory distress, of whom 4 required ventilation by HFO. HFO was also the mode of ventilation used in all cases except 1 during the perioperative period. There was no death from respiratory failure. The authors emphasize the usefulness of antenatal diagnosis, the efficiency of HFO in cases with severe respiratory failure, and well-tolerated early surgery.

[Haemophilus influenzae meningitis following vaccination. Consequence or coincidence?].

BACKGROUND: The introduction of vaccines against Haemophilus influenzae type b (Hib) has had a substantial impact on Hib infections. Their use has established their excellent safety profiles but occasional adverse effects have been reported. CASE REPORT: A 4 month-old infant was admitted for a severe form of Hib meningitis with septicemia whose first manifestations developed 3 hours after the first immunization with a conjugate vaccine against Hib (PRP-T). The outcome was good without any sequelae. DISCUSSION: A dramatic decrease in serum antibodies due to antigen-antibody reaction during the first days after immunization has been reported; this mechanism and some epidemiological data could favor the hypothesis that the vaccine is responsible for the infection, at least the unconjugated vaccines. CONCLUSION: Any fever occurring in the immediate post-immunization period must alert the possibility of a Hib infection.

The standard of spirometry in the RSA.

Standards for high-quality lung function testing have not yet been formally adopted in the RSA, despite the increase in the performance of spirometry. A study was undertaken to determine the standard of spirometry in clinical practice in this country. Forty-five spirometer users agreed to participate. Responses to a questionnaire, administered by personal interview, were graded according to the proportion of correct or appropriate answers: completely unsatisfactory less than 33.3%; poor 33.3-66.6%; and satisfactory greater than 66.6%. Only 6 spirometers were regularly calibrated. Knowledge of international standards for spirometry, the basic working mechanism of the spirometer being used and calibration ranged from poor to completely unsatisfactory in most of the practices. Instructions to the patients for performing the manoeuvres were satisfactory, but elevation of the result for acceptability, reproducibility, selection of the best test and diagnosis of a positive bronchodilator response were generally completely unsatisfactory. Only 18 practitioners knew the source of the reference values they used and 5 had proved their validity with a sample. Fourteen of the 45 practitioners were unable to make the correct diagnoses from two typical test results. Of the 45 practitioners, 40 were interested in a course in practical, clinical spirometry. In the light of the predominantly unsatisfactory results obtained in this study, we consider clinical spirometry to be an urgent priority for all levels of medical education.
