Randomized Controlled Trial
The use of lubrication in flexible fibreoptic nasendoscopy: a randomized controlled trial.
To determine how lubrication of the endoscope prior to flexible fibreoptic nasendoscopy affects levels of patient discomfort and pain during endoscopy. To assess the extent to which lubrication affects the ease of nasendoscopy and the quality of the image obtained. ⋯ Lubrication of the endoscope prior to nasendoscopy does not reduce levels of discomfort or pain for the patient, but increases ease in insertion for the operator. However, this may be at the expense of reduced image quality.
