Insights
Chlorhexidine Gluconate (CHG) dressings showed a significant reduction in Gram-positive Catheter-Related Bloodstream Infections (CRBSIs). While overall CRBSI rates were similar, CHG dressings proved effective against specific bacterial types.
Area of Science:
- Infection Control
- Medical Device Associated Infections
- Antimicrobial Stewardship
Background:
- Catheter-Related Bloodstream Infections (CRBSIs) are a significant concern in intensive care settings.
- Transparent dressings are commonly used for vascular access sites, but their antimicrobial properties vary.
- Chlorhexidine Gluconate (CHG) is a broad-spectrum antiseptic with proven efficacy against various microorganisms.
Purpose of the Study:
- To compare the effectiveness of Chlorhexidine Gluconate (CHG)-impregnated dressings versus standard non-antimicrobial transparent dressings in preventing CRBSIs.
- To evaluate the impact of CHG dressings on the incidence of CRBSIs, specifically focusing on causative microorganisms.
Main Methods:
- A prospective, comparative, single-center clinical study was conducted in a pediatric intensive care unit.
- Patients with jugular vein catheterization for ≥48 hours were included.
- The study utilized a crossover design with alternating phases of standard non-antimicrobial dressings and CHG-impregnated dressings to mitigate temporal biases.
Main Results:
- The study included 68 patients in the standard-dressing group and 63 in the CHG-dressing group, with similar catheterization durations.
- The overall CRBSI rate was slightly lower in the CHG group (20.6%) compared to the standard group (26.5%), but this difference was not statistically significant.
- A statistically significant reduction in CRBSIs caused by Gram-positive microorganisms was observed in the CHG-dressing group (0%) compared to the control group (8.8%; p=0.028).
Conclusions:
- Chlorhexidine Gluconate (CHG) dressings significantly reduce CRBSIs caused by Gram-positive microorganisms.
- While overall CRBSI rates did not differ significantly, CHG dressings offer targeted protection against specific pathogens, contributing to infection control strategies.
Objective:
We compared the protective effects of secure Chlorhexidine Gluconate (CHG)-containing dressings with those of non-antimicrobial transparent dressings.
Methods:
This prospective, comparative, single-center clinical study was conducted in a tertiary pediatric intensive care unit from October 2014 to March 2017. The inclusion criterion was catheterization of the jugular vein for ≥48 hour. The study was conducted in two phases. Non-antimicrobial standard dressings were applied both before and after the CHG- dressing phase to negate any coincidental temporal effect. During the standard-dressing phases, the dressings did not include any antimicrobial; transparent CHG-impregnated dressings were applied during the test phase. All patients were divided into two groups by the type of dressing applied (standard and CHG-containing dressings).
Results:
The standard- and CHG-dressing groups contained 68 and 63 patients, respectively. The median durations of catheterization were 13 (8-22) and 14 (2-28) days, respectively (p>0.05). The Catheter-Related Bloodstream Infection (CRBSI) rate was somewhat lower in the CHG-dressing group (20.6 vs. 26.5%), but the difference was not statistically significant (p>0.05). In the CHG-dressing group, CRBSIs caused by Gram-positive microorganisms totaled 0%, but the figure was 8.8% in the control group (p=0.028).
Conclusions:
CHG dressings reduced CRBSIs caused by Gram-positive microorganisms.
