Endocarditis risks.

BACKGROUND: A Cochrane Review from October 1998 recommends prophylactic antibiotics for all women undergoing elective and non-elective caesarean section. This is expected to reduce the frequency of postoperative endometritis by two thirds to three quarters. In this study we evaluate the infection rate after caesarean section in a hospital where prophylactic antibiotics are given only to high-risk groups. METHODS: Case records of 344 patient delivered by caesarean section were studied. 30 days after the operation, 83% answered a questionnaire about wound infection. RESULTS: In all, 39% received prophylactic antibiotics. 33 patients (9.6%) developed post-cesarean infections; only 17 were given antibiotic treatment. One patient had endometritis. There were no significant differences with regard to infections between the elective and the non-elective groups (p = 0.63), or between those receiving and those not receiving antibiotic prophylaxis (p = 0.84). CONCLUSION: The policy of selective use of prophylactic antibiotics for caesarean sections has been successful in our hospital. This study does not permit conclusions as to whether selective prophylactics is a better alternative than routine prophylactics, but the results question whether the recommendation in the Cochrane Review is the best choice for all delivery units.

Prevention of perinatal group B streptococcal disease. Revised guidelines from CDC.

Group B streptococcus (GBS) remains a leading cause of serious neonatal infection despite great progress in perinatal GBS disease prevention in the 1990s. In 1996, CDC, in collaboration with other agencies, published guidelines for the prevention of perinatal group B streptococcal disease (CDC. Prevention of perinatal group B streptococcal disease: a public health perspective. MMWR 1996;45[RR-7]:1-24). Data collected after the issuance of the 1996 guidelines prompted reevaluation of prevention strategies at a meeting of clinical and public health representatives in November 2001. This report replaces CDC's 1996 guidelines. The recommendations are based on available evidence and expert opinion where sufficient evidence was lacking. Although many of the recommendations in the 2002 guidelines are the same as those in 1996, they include some key changes: * Recommendation of universal prenatal screening for vaginal and rectal GBS colonization of all pregnant women at 35-37 weeks' gestation, based on recent documentation in a large retrospective cohort study of a strong protective effect of this culture-based screening strategy relative to the risk-based strategy * Updated prophylaxis regimens for women with penicillin allergy * Detailed instruction on prenatal specimen collection and expanded methods of GBS culture processing, including instructions on antimicrobial susceptibility testing * Recommendation against routine intrapartum antibiotic prophylaxis for GBS-colonized women undergoing planned cesarean deliveries who have not begun labor or had rupture of membranes * A suggested algorithm for management of patients with threatened preterm delivery * An updated algorithm for management of newborns exposed to intrapartum antibiotic prophylaxis Although universal screening for GBS colonization is anticipated to result in further reductions in the burden of GBS disease, the need to monitor for potential adverse consequences of intrapartum antibiotic use, such as emergence of bacterial antimicrobial resistance or increased incidence or severity of non-GBS neonatal pathogens, continues, and intrapartum antibiotics are still viewed as an interim strategy until GBS vaccines achieve licensure.
