Correlation study of external fixation method with catheter associated urinary tract infection

Abstract

Objective To observe and analyze the effect of different external fixation methods on catheter related urinary tract infection (CAUTI). Methods The clinical data of 86 patients suffered from indwelling catheters were retrospectively analyzed.According to the different external fixation of indwelling catheter, the patients were divided into observation group (n=43) and control group (n=43). The control group received drainage tube fixed in the bedside the legs go below, the observation group received drainage tube fixed on the bed after upper thigh walking.The incidence of complications was analyzed in the two groups. Results The incidence rates of CAUTI, leakage of urine, skin indentation of the observation group were 13.95%, 6.98% and 2.33%, respectively, which were lower than those of the control group (34.88%, 30.23% and 23.26%), there were statistically significant differences between the two groups (χ2=11.869, 17.848, 19.630, all P 0.05). Conclusion For the patients of indwelling catheter, drainage tube is fixed on the bed by the upper thigh walking is helpful to reduce skin pressure, reduce catheter infection and urine leakage rate, and can improve the comfort degree of patients, it is worthy of clinical popularization and application.
