(A). LCMS analysis of vancomycin in effluent samples from antibiotic loaded calcium sulfate beads with an antibiotic loaded PMMA spacer (CSBv+tplusSpacerv+t), antibiotic loaded PMMA spacer (Spacerv+t), and vancomycin powder bolus (VP). N = 9; geometric mean ±SE. The yellow curve is the influent saline flow rate. Time is shown on a log2 scale to more clearly show the changes in concentration at the early time points. (B). Log difference of vancomycin effluent concentrations of the CSBv+tplusSpacerv+t compared to the Spacerv+t alone. (* p < 0.05, ** p < 0.01).
