The effects of different central venous line dressing changes on bacterial growth in a pediatric oncology population
Insights
This study found no significant difference in microorganism growth on central venous lines when comparing Hibiclens and Betadine antiseptics. However, Betadine was associated with more skin redness and swelling in pediatric oncology patients.
Area of Science:
- Pediatric Oncology
- Infectious Disease Prevention
- Medical Device Management
Background:
- Central venous lines are essential for long-term intravenous access in pediatric patients.
- Infections associated with central venous lines are a significant concern.
- Optimizing skin antisepsis and dressing protocols is crucial for infection control.
Purpose of the Study:
- To compare the efficacy of Hibiclens (chlorhexadine) and Betadine (povidone-iodine) antiseptics.
- To evaluate the impact of Tegaderm and gauze dressings on microorganism growth.
- To assess the incidence of skin irritation and infection in pediatric oncology patients with central venous lines.
Main Methods:
- A randomized controlled trial involving 60 pediatric oncology and bone marrow transplant patients.
- Four dressing groups were established: Betadine/Tegaderm, Betadine/gauze, Hibiclens/Tegaderm, and Hibiclens/gauze.
- Quantitative cultures and clinical assessments for redness and swelling were performed before and after dressing changes.
Main Results:
- No significant differences in bacterial growth were observed between the antiseptic and dressing groups.
- Betadine antiseptic was associated with a higher incidence of skin redness and swelling compared to Hibiclens.
- Infection rates were higher in male patients than in female patients.
Conclusions:
- Both Hibiclens and Betadine, with either Tegaderm or gauze, appear equally effective in preventing microorganism growth on central venous lines in this pediatric population.
- Hibiclens may be preferred due to a lower incidence of local skin reactions.
- Further research is needed to understand gender-based differences in infection rates.
Abstract:
Central venous lines are now common in children who need a permanent form of intravenous access. These lines frequently become infected. This study compared the effects of different antiseptics (Hibiclens [chlorhexadine 4%; Stuart Pharmaceutical, Wilmington, DE] and Betadine [povidone-iodine, Clini Pad Corp, Guilford, CT]) used to clean the skin as well as the dressings used to cover the exit site (Tegaderm [3-M Medical-Surgical Division, St Paul, MN] and gauze) on microorganism growth on the skin in a pediatric oncology population. Sixty subjects were recruited from the oncology and bone marrow transplant units of Children's Hospital in Boston, MA. The subjects were randomly assigned to one of four dressing groups. These included: 1, Betadine and Tegaderm; 2, Betadine and gauze; 3, Hibiclens and Tegaderm; and 4, Hibiclens and gauze. Dressings were done on a Monday-Wednesday-Friday basis. Quantitative cultures were obtained before the first and after the fifth dressing changes. There were no significant differences in incidence of bacterial growth between dressing groups (F = 1.05, P = .377). Redness (F = 3.01, P = .037) and swelling (F = 2.75, P = .051) were more frequently seen in Betadine groups. Boys were more often infected than girls. (Chi 2 = 4.075, P = .044).
