Evaluation of tow types of dressings used on central venous catheters for hemodialysis

Objectives: To evaluate the efficacy of two types of dressings used on central venous catheter (CVC) in patients undergoing hemodialysis and to determine the rate of local and systemic bacterial infection when using gauze and micropore dressings or transparent film dressings. Methods: This study was a controlled randomized clinical trial with 66 Subjects who were equally assigned to two groups (33 subjects per group). Group 1 used gauze and micropore dressings and group 2 used transparent film dressings. Measures consisted of a socio demographic questionnaire, clinical data, and catheter tip and blood culture tests. Subjects remained in the study until removal of the catheter. Results: There were no statistically significant differences regarding the types of dressings. Positioning of CVCs at 90 degrees in relation to the skin had higher rate of infections by S. Aureus. Conclusion: Although the use of transparent film dressings did not reduce infection, qualitative data analysis suggested that: this type of dressing was preferred by the patients and by the health care providers from a university hospital.
