Summary

This trial tests whether adding nebulized ketamine to lidocaine before a fiberoptic bronchoscopy reduces coughing and discomfort compared to lidocaine alone or standard spray. About 134 adults scheduled for bronchoscopy will receive one of three premedication approaches. The study tracks cough severity, patient tolerance, satisfaction, and safety, including blood pressure and oxygen levels.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Nebulized lidocaine and ketamine
What this could lead to: If effective, this combination could make bronchoscopy more comfortable and safer, reducing coughing and improving patient tolerance during the procedure.
What could go wrong: This is a single-center trial with a modest number of participants, and the added benefit of ketamine may be small or come with side effects like sedation or blood pressure changes.
