1. A method of reducing an incidence of infection in a patient at a surgical site associated with a surgical procedure, the method comprising:
- identifying a region of tissue of the patient that will be exposed during the surgical procedure;
subcutaneously introducing a solution comprising a dose of a drug dissolved therein through a skin of the patient at a location to or in a vicinity of the identified region of tissue;
applying ultrasound transcutaneously toward the identified region of tissue and the subcutaneously introduced solution, wherein the transcutaneously applied ultrasound interacts with the solution to disperse the solution with the dose of drug dissolved therein through the identified region of tissue;
exposing the identified region of tissue to air; and
performing the surgical procedure.

Abstract
Antibiotics are administered in a surgical site subcutaneously via a small or stab incision in the surgical field. Transcutaneous ultrasonic vibrations are applied across the surgical field, which is then opened in the usual manner, to thereby provide a surgical field which contains a vastly higher and more effective level of antibiotic. At the same time the underlying tissue is hydrated.

11. A method of open surgery, the method comprising:
-
identifying a tissue site of the patient that will be exposed during the open surgery; preparing a tissue site for the open surgery by; subcutaneously introducing a solution comprising a dose of an antibiotic dissolved therein through a skin of the patient at a location to or in a vicinity of the identified tissue site; applying ultrasound transcutaneously toward the identified tissue site and the subcutaneously introduced solution, wherein the transcutaneously applied ultrasound interacts with the solution to disperse the solution with the dose of antibiotic dissolved therein through the identified region of tissue, the dose of antibiotic dissolved in the solution being dispersed through the infected tissue at therapeutically effective concentrations for reducing an incidence of infection at the identified region of tissue during the open surgery. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system for preparing a tissue site of a patient for an open surgery procedure, the system comprising:
-
a cannula for subcutaneously injecting a solution with a dose of an antibiotic dissolved therein to a tissue site of the patient that will be exposed to air during the open surgery; an ultrasound system configured to broadcast ultrasound transcutaneously toward the identified tissue and the subcutaneously injected solution, wherein the ultrasound system is configured to broadcast ultrasound at a power density of 2.5 to 4 W/cm2 and at a frequency of less than 5 MHz that is configured to interact with the subcutaneously injected solution to disperse the subcutaneously injected solution with the dose of antibiotic dissolved therein through the tissue at a concentration; and
wherein the concentration of antibiotic in the identified tissue is therapeutically effective for reducing an incidence of infection at the identified tissue during the open surgery. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
