Effect of reducing the incidence of CAUTI by using JUS antibacterial material

Abstract

Objective To observe the effect of reducing the incidence of CAUTI (catheter associated urinary tract infection) by spraying the long-acting physical antibacterial material JUS on the surface of catheter and urethral orifice.Methods 70 patients, aged from 14~90, with indwelling catheter, were divided randomly into two groups (control group and treated group), each consisting of 35 patients. For the control group, their urethral orifice was treated conventionally twice a day; while for the treated group, in addition to the conventional treatment of their urethral orifice, the catheter and urine bag connection were sprayed with the long-acting antibacterial material JUS twice a day.Results The number of cases of urinary tract infection in the treated group during catheterization was evidently less than those of the control group (χ2=24.587,P<0.05), so the difference was significance.Conclusions The long-acting antibacterial material, after spraying on the wall of catheter and urethral orifice of the patients with indwelling catheter, may form a layer of physically antibacterial molecular film to prevent the formation of a bacterial biological film and effectively reduce the incidence of urinary tract infection.
