Could a cup of tea prevent pneumonia in ICU patients?
NCT ID NCT07688057
First seen Jul 07, 2026 · Last updated Jul 09, 2026 · Updated 2 times
Summary
This study tests whether mouth care with green tea or white tea can prevent ventilator-associated pneumonia (VAP) as well as the standard antiseptic chlorhexidine. It includes adults in intensive care who are on breathing machines. The goal is to see if these natural alternatives reduce pneumonia rates while improving oral health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- chlorhexidine, green tea, white tea
- What this could lead to
- If green or white tea proves as effective as chlorhexidine, it could offer a simpler, more natural option for preventing pneumonia in ventilated patients.
- What could go wrong
- This is a small study (63 patients) and results may not apply to all ICU settings. The teas might not prevent pneumonia as well as the standard antiseptic.
