Decontamination with chlorhexidine gluconate reduces the incidence of ventilator associated pneumonia

Abstract:
Ventilator-associated pneumonia is a major source of nosocomical infection affecting about 27 percent of all critically ill patients. In this study, an attempt was made to assess the effect of oral decontamination with 0.2% chlorhexidine gluconate solution and hydrogen peroxide solution on the incidence of ventilator-associated pneumonia and oropharyngal colonisation. Seventy patients above 18 years of age admitted in AIIMS, New Delhi were included as subjects. It was concluded that incidence of ventilator-associated pneumonia was higher in patients given oral care with hydrogen peroxide than those on 0.2% chlorhexidine, which was more effective in reducing orophyryngeal colonisation.
Insights
Oral care with 0.2% chlorhexidine gluconate significantly reduces ventilator-associated pneumonia (VAP) and oropharyngeal colonization compared to hydrogen peroxide. Chlorhexidine demonstrated superior efficacy in preventing VAP in critically ill patients.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Oral Hygiene
Background:
- Ventilator-associated pneumonia (VAP) is a prevalent nosocomial infection, impacting approximately 27% of critically ill patients.
- Effective VAP prevention strategies are crucial for improving patient outcomes in intensive care settings.
Purpose of the Study:
- To evaluate the efficacy of oral decontamination using 0.2% chlorhexidine gluconate and hydrogen peroxide solutions.
- To compare the incidence of VAP and oropharyngeal colonization between the two oral care interventions.
Main Methods:
- A study involving seventy adult patients admitted to AIIMS, New Delhi, requiring mechanical ventilation.
- Patients received oral care with either 0.2% chlorhexidine gluconate or hydrogen peroxide solution.
Main Results:
- The incidence of VAP was higher in the group receiving oral care with hydrogen peroxide.
- 0.2% chlorhexidine gluconate was more effective in reducing oropharyngeal colonization.
- Chlorhexidine demonstrated a trend towards lower VAP rates.
Conclusions:
- 0.2% chlorhexidine gluconate is more effective than hydrogen peroxide for oral decontamination in preventing VAP.
- Chlorhexidine-based oral care is recommended for critically ill patients on mechanical ventilation to reduce infection risk.
