A Study to Analyze the Amount of Antibiotic Absorbed into Tissues Comparing Two Different Modes of Administration


About this study

This study aims to investigate whether administration of vancomycin intravenously via a Bier block, typically a method for providing regional anesthesia in the upper extremity, leads to higher soft tissue and bone antibiotic concentrations compared to routine intravenous administration.  Higher tissue concentrations could be desirable for prophylaxis in complex upper extremity reconstruction, or for treatment of difficult infections.
