Durability of antimicrobial activity of antibiotic-impregnated external ventricular drains: a prospective study

Background Antibiotic-impregnated external ventricular drains (AI-EVDs) have a debated efficacy in clinical studies. Objectives Our aim was to assess the durability of antimicrobial activity of AI-EVDs used in clinical settings. Methods From April 2017 to January 2018, all consecutive AI-EVDs (Bactiseal™) inserted in adult patients were prospectively included.
