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

MeasureTime frameDescription
Colony forming unit (CFU) counts of EBUS-TBNA needle wash solution in aerobic mediaNeedle wash solution is obtained immediately after termination of EBUS-TBNANeedle wash solution is obtained by instilling 5mL of sterile physiological saline into the puncture needle.

Secondary

MeasureTime frameDescription
CFU counts of EBUS-TBNA needle wash solution in anaerobic mediaNeedle wash solution is obtained immediately after termination of EBUS-TBNANeedle wash solution is obtained by instilling 5mL of sterile physiological saline into the puncture needle.
Fever24 hours after EBUS-TBNAFever is defined as a temperature ≥37.8°C.
Infectious complications4 weeks after EBUS-TBNAInfectious complications include pneumonia, lung abscess, empyema, mediastinal adenitis/abscess, mediastinitis, pericarditis, and sepsis.
