Abstract:
Objective To apply the hydrocolloid dressings and hydrocolloid dressings combined GreenCream Dressing for central venous catheterization fixing, and to explore the effect of hydrocolloid dressings combined GreenCream Dressing in the prevention of venous catheter bacterial colonization and bacterial infection. Methods 470 patients who underwent the Inferior vena cava catheter were divided into 230 patients in the control group and 240 patients in the experimental group. The control group was fixed with hydrocolloid dressings after central venous catheter, and the experimental group was fixed with hydrocolloid dressings combined GreenCream Dressing after central vein catheter. The measurements included catheter bacterial colonization, catheter-related infections (CRIs) and catheter related blood stream infections (CR-BSIs), pathogenic bacteria colonization of the skin. At the same time, the skin safety was also confirmed. Results In the control group, 230 cases were retained for 1 419 catheter-days, and 240 cases in the experimental group were retained for 1 675 catheter-days. Compared with hydrocolloid dressings, hydrocolloid dressing combined GreenCream Dressing could reduce the incidence of CRIs from 1.8‰(3/1 675) to 0.7‰(1/1 675), and CR-BSIs from 2.4‰(4/1 675) to 0.7‰(1/1 675) respectively, with the statistically significant (χ2=6.39, 95%CI 1.30-31.41, andχ2=6.21, 95%CI 1.56-40.82;P<0.05). The results of bacterial colonization, CRIs and CR-BSIs showed that the most common bacteria were Staphylococcus and fungi. At the same time, compared with the hydrocolloid dressing, hydrocolloid dressing combined GreenCream dressing could reduce the incidence of skin pathogenic bacteria colonization, from 41.74%(96/230) to 28.33%(68/230),with the statistically significant (χ2=9.29,P=0.00);There was no difference between the two groups in the field of the incidence of abnormal skin manifestation (χ2=1.23, P=0.30), showing a good safety. Conclusions Hydrocolloid dressing combined GreenCream Dressing would be more effective to prevent bacterial colonization and bacterial infection of central venous catheter in department of neurosurgery.
