[Prevention of early-onset group B Streptococcus infections. 1. Application of the ANAES guidelines].

OBJECTIVES: To examine adherence to the Anaes guidelines for early-onset infections prophylaxis, based on a systematic prenatal vaginal swab aiming group B Streptococcus and/or infection risk factors during delivery. PATIENTS AND METHODS: Retrospective study of 6125 consecutive deliveries through a 28-month period. Data were collected from the patients files recorded in a computer database. RESULTS: Overall, a vaginal swab was performed on 88.3% of the patients. Among these, 79.1% were performed according to the guidelines. Among the patients, 90.2% with a positive swab received intrapartum antibiotics. In accordance to the national guidelines, we noticed a 40% increase in the consumption of antibiotics, without any severe complication during the study. Certain points must be improved though: time of the sampling, antibiotic therapy in case of quick delivery, management of patients with allergy to penicillin. CONCLUSION: Concordance with the national guidelines is feasible in a department with a high obstetrical activity.
