Background: Implanting hardware into surgical sites increases the rate of infection associated with these sites. Without novel efforts to reduce this rate of infection, we can expect to see an increase in the number of hardware-associated infections as more patients are implanted with these devices. These infections often necessitate the removal of these devices resulting in a significant financial and clinical burden to patients. We developed a prototype antibiotic coating using products that are both low cost and that can be sourced easily. Our study aims to test the effectiveness of this coating against bacteria commonly observed in hospital-associated infections. Methods: The antibiotic coating was prepared by combining one gram of vancomycin and 500 mg of ciprofloxacin in 50 mL of glycerol. The coating was examined for inhibition of growth of Pseudomonas aeruginosa PA14 and Staphylococcus aureus AH2486 and compared with the bacterial growth of the above bacteria in glycerol alone. The growth curves were plotted measuring the bacterial growth at 5 h intervals. Results: The results of the growth curves clearly demonstrate a lack of bacterial growth when these bacteria are combined with glycerol combined with our selected antibiotic agents. Conclusion: There appears to be a limited interest from device companies in developing new strategies for infection prevention associated with neurosurgical hardware, and we propose that this prototype will be an effective and low-cost solution to a large problem.
