Audiovisual distraction reduces pain perception during aural microsuction

Introduction

Aural microsuction is a common ear, nose and throat procedure used in the outpatient setting. Some patients, however, find it difficult to tolerate owing to discomfort, pain or noise. This study evaluated the effect of audiovisual distraction on patients’ pain perception and overall satisfaction.

Methods

A prospective study was conducted for patients attending our aural care clinic requiring aural toileting of bilateral mastoid cavities over a three-month period. All microsuction was performed by a single clinical nurse specialist. Any patients with active infection were excluded. For each patient, during microsuction of one ear, they watched the procedure on a television screen while for the other ear they did not view the procedure. All patients received the same real time explanations during microsuction of both ears. After the procedure, each patient completed a visual analogue scale (VAS) to rate the pain they experienced for each ear, with and without access to the television screen. They also documented their preference and reasons why.

Results

A total of 37 patients were included in the study. The mean pain score for patients viewing the procedure was 2.43 compared with a mean of 3.48 for patients with no television view. This difference in patients’ pain perception was statistically lower in the group who observed the procedure on the television (p=0.003), consistent with the majority of patients reporting a preference to viewing their procedure (65%).

Conclusions

Audiovisual distraction significantly lowered patients’ VAS pain scores during aural microsuction. This simple intervention can therefore reduce patients’ perceived pain and help improve acceptance of this procedure.
