General information about the trial
|
|||
Main objective of the trial |
The objective of this trial is to asses the penetration of vancomycin into bone tissue using the pharmacokinetic tool microdialysis.
The primary endpoint is the area under the concentration-time curve (AUC) above the MIC (minimal inhibitory concentration) for staphylococcus aureus. Secondary endpoints are standard pharmacokinetic parameters.
