The principal aim of the present research is to compare two methods of antibiotic delivery: concomitant tumescent antibiotic delivery (TAD) and intravenous antibiotic delivery (IVAD) versus IVAD alone, (TAD+IVAD vs IVAD), with respect to the prevention of surgical site infections (SSI). The investigators hypothesize that TAD+IVAD will significantly reduce the incidence of SSI compared to IVAD.
