Terminology Flashcards
Analgesia
a loss of sensitivity to pain
Nociception
the neural process of encoding noxious stimuli
Does not require consciousness
Tranquilization
a state of behavioral change, wherein anxiety is relieved and the patient is relaxed, although aware of its surroundings
Sedation
a state characterized by CNS depression accompanied by drowsiness.
Likely unaware of its surroundings
Local anesthesia
a loss of sensation in a circumscribed body area
Regional anesthesia
loss of sensation in a larger, though limited body area
Narcosis
a drug induced state of deep sleep from which a patient cannot be easily aroused. It may or may not be accompanied by antinociception.
General anesthesia
drug-induced unconsciousness characterized by controlled, reversible depression of the CNS and perception.
the patient is not arousable by noxious stimulation. Sensory, motor, and autonomic reflex functions are attenuated to varying degrees
Dissociative anesthesia
Induced by drugs that dissociated the thalamocortical and limbic system
What is an example of a Dissociative anesthesia?
Ketamine
Telazol
What is characteristic of a Dissociative anesthesia?
Catatonic State
Eyes remain open
swallowing reflexes remain functional
skeletal muscle rigidity
Surgical anesthesia
the stage/plane of general anesthesia that provides unconsciousness, muscle relaxation and analgesia sufficient for painless surgery
Balanced anesthesia
induced by a multiple drug approach.
Drugs are targeted to attenuate individual components of the anesthetic state; unconsciousness, analgesia, muscle relaxation
What are the routes of administration for Anesthesia?
Inhalation Injectable Oral Transmucosal Intranasal
