The use of visual distraction to improve the tolerability of flexible laryngoscopy.

BACKGROUND: Flexible laryngoscopy is a commonly performed procedure in otolaryngology. Although this procedure is not considered painful, many patients describe it as uncomfortable. This study investigated the role of visual distraction as a form of pain relief during flexible laryngoscopy.

METHODS: The study included patients undergoing flexible laryngoscopy at the University Hospital Southampton. Patients were self-allocated to one of four groups: with or without co-phenylcaine anaesthetic spray; and with and without visual distraction. Visual distraction involved the patient watching the procedure concurrently with the clinician, via a video monitor. Pre- and post-procedural discomfort was assessed using a visual analogue scale.

RESULTS: The use of topical anaesthetic spray was not associated with significantly reduced discomfort scores (p > 0.05). Discomfort scores were significantly reduced in the visual distraction groups (p = 0.04), irrespective of the use of topical anaesthetic spray.

CONCLUSION: This small study showed that visual distraction should be considered as a simple and cost-effective alternative to local anaesthetic for flexible laryngoscopy.
