Inhaled Anesthetic Flashcards
Stage of anesthesia:
Decreased awareness of pain
Impaired consciousness
Analgesia
State of General Anesthesia
Unconsciousness Analgesia Amnesia Skeletal Muscle Relaxation Loss of reflexes
Stage of anesthesia:
Delirium or excitement
Irregular respiration
Incontinence or retching
Disinhibition
Stage of anesthesia:
Unconsciousness
No pain reflex, maintained respiration and BP
Surgical Anesthesia
Stage of anesthesia:
Severe respiratory and CVS depression
Mechanical and pharmacological support needed
Medullary depression
Stages of anesthesia in order: A. medullary depression B. surgical anesthesia C. analgesia D. disinhibition
