Study Details

This study aims to evaluate the effects of chewing gum and gargling with cold water on common post-bronchoscopy symptoms, such as sore throat and difficulty swallowing (dysphagia). Bronchoscopy is a procedure that can cause temporary throat discomfort. In this randomized controlled trial, patients will be divided into groups to receive either chewing gum, cold water gargle, or standard care. The researchers will then measure and compare patient satisfaction levels and the severity of throat symptoms to determine if these simple interventions can improve patient comfort after the procedure.
