Insights
A new antimicrobial gel containing cetrimide, bacitracin, and polymyxin B sulfate effectively prevented clinical infections in minor wounds. This topical treatment significantly reduced infection rates compared to placebo in a school setting.
Area of Science:
- Dermatology
- Infectious Diseases
- Wound Care
Background:
- Minor wounds are common in children, posing a risk of infection.
- Effective topical antimicrobial prophylaxis is crucial for preventing wound complications.
Purpose of the Study:
- To evaluate a novel topical antimicrobial gel containing cetrimide, bacitracin, and polymyxin B sulfate for preventing infections in minor wounds.
- To compare its efficacy against placebo and povidone iodine antiseptic cream.
Main Methods:
- A prospective clinical trial was conducted in five primary schools in Sydney, Australia.
- Children aged 5-12 years with minor accidental injuries were treated with the test gel, placebo, or povidone iodine.
- Wound outcomes were assessed after 3 days for clinical and microbiologic infection.
Main Results:
- The novel gel significantly reduced the incidence of clinical infections from 12.5% to 1.6% (p < 0.05).
- No significant differences in microbiologic infections were observed among the treatment groups (p > 0.05).
Conclusions:
- The novel antimicrobial gel demonstrated therapeutic action in reducing clinical infections in minor accidental wounds.
- This preparation may be a suitable option for first-aid wound prophylaxis.
Objective:
To evaluate the ability of a novel topical antimicrobial gel containing cetrimide, bacitracin, and polymyxin B sulfate to prevent infections of minor wounds.
Design:
A clinical trial compared the test preparation with placebo and a povidone iodine antiseptic cream.
Setting:
Five primary schools in Sydney, Australia, participated in the study over a 6-week spring/summer school term.
Subjects:
Children aged 5-12 years with parental consent were eligible for study participation. Accidental injuries occurring at school were treated in a standardized manner by nurses at each site.
Outcome Measures:
Wounds were evaluated by the medical practitioner after 3 days of topical treatment. The clinical outcome was classified as resolution or suspected infection. If a clinical infection was suspected, the injury was swabbed for microbiologic evaluation. Growth of a dominant microorganism was classified as a microbiologic infection.
Results:
Of the 177 injuries treated, there were nine clinical infections. A comparison of these showed a significant difference among treatment groups (p < 0.05). This difference was associated with the test preparation and placebo; the test preparation reduced the incidence of clinical infection from 12.5% to 1.6% (p < 0.05; 95% CI, 0.011 to 0.207). A comparison of microbiologic infections showed no significant differences among treatment groups (p > 0.05).
Conclusions:
The novel gel preparation containing cetrimide, bacitracin, and polymyxin B sulfate showed therapeutic action and reduced the incidence of clinical infections in minor accidental wounds. It may be a suitable product for first aid prophylaxis.
