What does obtunded mean?
Obtunded describes something that has been made dull, blunt, or less responsive to sensation. Its most familiar use is medical: an anaesthetic, analgesic, or local nerve block may leave pain obtunded, meaning that the sensation is reduced without necessarily disappearing. The word can also describe diminished hearing, touch, awareness, or emotional responsiveness, although such uses are often formal or literary. Obtunded differs from numb in suggesting a reduction in intensity rather than necessarily the complete absence of sensation. It also differs from obtuse, which concerns intellectual or perceptual sharpness rather than something being physically or medically dulled. The term comes from the Latin verb obtundere, meaning “to blunt” or “to make less sharp,” and preserves the idea of softening or blunting an originally acute response.
