Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A video consisting of various images and audio that stimulates patient relaxation will be reproduced by the operator and co-investigator of the study, during the nasal endoscopic procedure, which lasts around 40 minutes.
For the reproduction of the video, a virtual reality viewer, called Oculus Go (Facebook Technologies, LLC), will be used, in addition to hearing aids with surround sound. The video and sound content were created with copyright-free audiovisual material, in which landscape images and relaxation music are played throughout the whole procedure.
Also, the explanation video will be reproduced before the nasal endoscopy procedure.

Statistical methods / analysis
The calculated sample was determined by the ratio difference formula resulting in 54 patients, taking as reference a power of 80% and alpha of 5. The data will be reported as mean and standard deviation or median and range, accordingly to data normality distribution. To compare the standard deviation, a Fischer test will be applied in the correlation of coefficients. Confidence intervals of 95% will be used. Evaluation of qualitative variables through Chi square (tables 2x2 or 2x3) where the difference was established when the p was less than or equal to 0.05.

Summary
Brief summary
Upper gastrointestinal endoscopy is commonly performed procedure for the diagnostic approach of gastrointestinal diseases. Authors design a randomized clinical trial with adult patients who required a diagnostic upper gastrointestinal endoscopy, to compare the anxiety score, in the interventional vs control group, 30 minutes post nasal endoscopy procedure.

In the intervention and control group a brief explanation before the nasal endoscopy procedure, with video images and audio-guided description will be reproduced. In addition, the intervention group, a second video with images and audio that stimulates patient relaxation, will be reproduced during the nasal endoscopic procedure. The study hypothesis is relaxation video and images effectively decreases the anxiety in patients who undergo nasal endoscopy.
