[Preventive antibiotic therapy in neurosurgery].

The swiss neurosurgeons were asked to give their own politics on prophylactic antibiotics. The results of this enquiry are given. Post-operative infections in the Neurosurgical Clinic of Geneva in a four-year period were at a satisfactorily low rate and demonstrated the importance of many factors of risk. Guide lines for a reasonable prophylaxis in three groups of operations are given, with a precise schedule for each group. It is suggested that ones own surgical technique be severely criticized before considering prophylactic antibiotics.
