Brief summary
The purpose of this study is to investigate whether chlorhexidine mouthrinse is effective in preventing microbial contamination during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).
Detailed description
EBUS-TBNA using the convex probe is a standard of care for the assessment of mediastinal and hilar lymphadenopathy. Although EBUS-TBNA is a minimally invasive procedure, rare but serious infectious complications such as pneumonia, lung abscess, empyema, mediastinal adenitis/abscess, mediastinitis, pericarditis, and sepsis were reported. EBUS-scope might be contaminated with oropharyngeal commensal bacteria while passing the oropharyngeal airway during EBUS-TBNA. Contamination of punctured lymph nodes by oropharyngeal commensal bacteria can cause severe infections. Chlorhexidine gluconate is an antimicrobial agent that has a broad antibacterial activity including both gram-positive and negative bacteria. Chlorhexidine has been widely used for surgical scrub, skin disinfection, and mouthrinse. We, therefore, designed a phase 4, single-center, randomized, controlled clinical trial to investigate whether chlorhexidine mouthrinse is effective in preventing microbial contamination during EBUS-TBNA.
Interventions
Intervention with chlorhexidine mouthrinse will be performed approximately 10 min before the start of EBUS-TBNA

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Colony forming unit (CFU) counts of EBUS-TBNA needle wash solution in aerobic media | Needle wash solution is obtained immediately after termination of EBUS-TBNA | Needle wash solution is obtained by instilling 5mL of sterile physiological saline into the puncture needle. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| CFU counts of EBUS-TBNA needle wash solution in anaerobic media | Needle wash solution is obtained immediately after termination of EBUS-TBNA | Needle wash solution is obtained by instilling 5mL of sterile physiological saline into the puncture needle. |
| Fever | 24 hours after EBUS-TBNA | Fever is defined as a temperature ≥37.8°C. |
| Infectious complications | 4 weeks after EBUS-TBNA | Infectious complications include pneumonia, lung abscess, empyema, mediastinal adenitis/abscess, mediastinitis, pericarditis, and sepsis. |
