About this study
Official title: Association Between Different Fasting Durations Before Bronchoscopy And The Discomfort Levels Of Patients Around The Procedure
The goal of this clinical trial is to learn if patients feel more comfortable while being placed on contemporary fasting principle than on conventional fasting time during flexible bronchoscopy. The main questions it aims to answer are:
To compare the thirty levels between patients with conventional fasting time (≥ 8 hours) and those with contemporary fasting principle (clear fluids for up to 2 hours before anesthesia) during flexible bronchoscopy To compare the levels of mucosal dryness between two groups of patients during flexible bronchoscopy To compare the levels of hunger between two groups of patients during flexible bronchoscopy To compare the levels of tiredness between two groups of patients during flexible bronchoscopy To compare the levels of fatigue between two groups of patients during flexible bronchoscopy To compare the levels of nausea/vomiting between two groups of patients during flexible bronchoscopy

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
patient thirty level (time frame: right before the bronchoscopy procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
