Abstract:
1. A method of minimizing infections at a surgical site, the method comprising the steps of: providing a solution containing an antibiotic and a vasoconstrictive drug; inserting a tubular needle having apertures into an adit of the patient such that the tubular needle is adjacent the surgical site to infiltrate the solution at the surgical site; flowing the antibiotic/vasoconstrictive drug solution through the tubular needle and out of the apertures to constrict the blood vessels and delay systemic absorption of the antibiotic for prolonging a length of time that the antibiotic remains at the surgical site; and performing surgery at the surgical site wherein a first surgical incision is made after a period of time has elapsed for the antibiotic/vasoconstrictive drug solution has permeated the surgical site during the flowing step.
