This single-site, participant-blinded randomized pilot study assessed whether a cotton buffer that dampens vibratory anesthetic device (VAD) vibration improves comfort in adults receiving applications at five anatomical sites. Among 53 participants, the dampened device was preferred at every site: preference ranged from 75.5% on the dorsal forearm to 88.7% at the lateral nasal wall and ear helix (all p < .001). Preference was strongest at face and head/neck sites (p = .018). Qualitative analysis identified smoother, gentler, more controlled, lower-frequency and lower-intensity sensations, and being less bothered, as reasons for preference.
Key findings
- The dampened VAD was preferred by 88.7% at the lateral nasal wall and ear helix, 84.9% at the submalar cheek, 77.4% at the lateral neck, and 75.5% at the dorsal forearm (all p < .001).
- Preference was strongest at face and head/neck sites (p = .018).
- Six themes associated with preference were Smoothness, Gentleness, Controlled, Low Frequency, Low Intensity, and Less Bothersome.
Why it matters
Vibration from anesthetic devices may feel harsh at sensitive injection sites, potentially affecting patient comfort. This pilot suggests that a simple cotton buffer can improve perceived comfort across several sites, with preference particularly strong at face and head/neck locations. The reported sensory themes help characterize what patients valued, while the pilot design means the findings warrant cautious interpretation.
What to keep in mind
This was a small, single-site pilot study; the abstract does not report longer-term outcomes or whether improved comfort changes device adoption.
