Flashcards in Introduction Deck (14):
1

Components of general anesthesia

Muscle relaxation
Narcosis
Analgesia

2

Why is it necessary?

Human care, ease of diagnostic procedures, protection of personnel

3

Analgesia

Loss of sensitivity to pain

4

Nociception

Neural process of encoding noxious stimuli, does not require consciousness

5

Tranquilization

Behavioral change where anxiety is relieved and patient is relaxed; still awake/aware of surroundings

6

Sedation

CNS depression and drowsiness; unlikely to be aware of surroundings

7

Local anesthesia

Loss of sensation in a circumscribed body area

8

Regional anesthesia

loss of sensation in larger, though limited, body area

9

Narcosis

Drug induced state of deep sleep from which a patient cannot be easily aroused; may or may not accompany nociception

10

General Anesthesia

Drug induced unconsciousness

Controlled, reversible depression of the CNS and perception; not arousable by noxious stimulation

11

Dissociative anesthesia

Caused by drugs that dissociate the thalamocortical and limbic systems

Catatonic state where eye remain open and swallowing reflexes remain; skeletal muscle rigidity common

12

Surgical anesthesia

State/plane of anesthesia that provides unconsciousness, muscle relaxation, and analgesia sufficient for painless surgery

13

Balanced anesthesia

Induced by use of multiple drugs targets to attenuate individual components of anesthesia

14

Routes of administration

Inhalations anesthetic gasses or vapors inhaled in combination with O2

Injectable- anesthetic solutions injected IM, SQ, or IV

Oral/transmucosal/intranasal- infrequently used with liquids or gels
