What's the difference between anaesthetic and consciousness?

Anaesthetic


Definition:

  • (a.) Capable of rendering insensible; as, anaesthetic agents.
  • (a.) Characterized by, or connected with, insensibility; as, an anaesthetic effect or operation.
  • (n.) That which produces insensibility to pain, as chloroform, ether, etc.

  • (20) Seven or 14 days of treatment with the beta 2-adrenoceptor agonist clenbuterol, 0.3 mg kg-1, s.c., twice daily, increased the basal mean blood pressure in normotensive urethane-anaesthetized rats.

Consciousness


Definition:

  • (n.) The state of being conscious; knowledge of one's own existence, condition, sensations, mental operations, acts, etc.
  • (n.) Immediate knowledge or perception of the presence of any object, state, or sensation. See the Note under Attention.
  • (n.) Feeling, persuasion, or expectation; esp., inward sense of guilt or innocence.

Example Sentences:
