Abstract
An infiltration cannula and method of using the infiltration cannula during a tumescent infiltration procedure are disclosed herein. The infiltration cannula may have an outwardly flaring hub which may be wedged into an adit of a patient to minimize leakage of fluid being infiltrated into the patient. Also, the infiltration cannula may be utilized to hydrate a dehydrated patient by a medically untrained person. The infiltration cannula may also be used to deliver an antibiotic/vasoconstrictive drug solution to minimize surgical site infections.
Claims2
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.
