What this Trial Is About
This research aims to evaluate whether chewing gum and cold water gargling can ease common throat discomforts, such as sore throat and difficulty swallowing, experienced after bronchoscopy. The study compares these simple interventions against standard care to see if they improve patient comfort and satisfaction following the procedure. Participants will be randomly assigned to one of three groups: chewing sugar-free xylitol gum for 15 minutes before bronchoscopy, gargling cold water (8-12°C) twice for 30 seconds each before the procedure, or receiving the usual care without additional treatments. The chewing gum and cold water gargle are supervised by researchers who provide instructions and ensure proper procedure. Participants' symptoms and satisfaction will be assessed before bronchoscopy, then at 2 hours and 24 hours after the procedure. The 24-hour follow-up will be done by phone. Researchers will measure the severity of sore throat and swallowing difficulty along with patient satisfaction, aiming to understand if these interventions affect recovery and comfort. The study starts with standard fasting and includes routine education about bronchoscopy.
