Flashcards in Chpt. 7 - Key Terms Deck (30):
1

Algesia

Sensitivity to pain

2

Analgesia

Absence of pain

3

Central nervous system hypersensitivity

A state, caused by constant nociceptive input from the periphery, in which neurons in the spinal cord become hyperexciteable and sensitive to low-intensity stimuli that would not normally elicit a pain response. Also referred to as windup.

4

Distress

An extreme form of stress that leads to anxiety and suffering

5

Emergence delirium

Disorientation that occurs during anesthetic recovery as consciousness returns. May be characterized by vocalization, aggression, thrashing, and locomotor activity.

6

Idiopathic

Of unknown or unidentifiable cause

7

Locomotor

Relating to movement from place to place

8

Mediators

Chemical substances released from damaged cells or inflammatory cells that cause a response (such as increasing the sensitivity of peripheral pain receptors.).

9

Modulation

The third step in nociception, in which sensory nerve impulses are amplified or suppressed by other neurons.

10

Morbidity

The incidence of disease

11

Mortality

The death rate

12

Multimodal therapy

Treatment of pain with analgesics that target two or more types of pain receptors.

13

Neuropathic

Resulting from injury of a nerve

14

Nociception

Detection by the nervous system of the potential for or actual tissue injury.

15

Pain

An aversive sensory and emotional experience that elicits protective motor actions, results in learned avoidance, and may modify species-specific behavior.

16

Pain scales

Any assessment tools used to rate the intensity of pain.

17

Pathologic pain

Pain that occurs after tissue injury

18

Perception

The final step of nociception, in which sensory impulses are transmitted to the brain, where they are processed and recognized.

19

Perioperative analgesia

Pain control before and /or after surgery.

20

Physiologic pain

The protective sensation of pain that occurs when there is no or minimal tissue injury.

21

Pre-emptive analgesia

Provision of analgesia before tissue injury, including surgery.

22

Primary hyperalgesia

A state of increased sensitivity near a site of tissue injury, in which stimulation with a normally non-noxious stimulus is painful

23

Secondary hyperalgesia

A state of increased sensitivity distant from a site of tissue injury, in which stimulation with a normally non-noxious stimulus is painful

24

Somatic pain

Pain originating form the musculoskeletal or integumentary system. Subclassified as superficial (i.e., skin) and deep (i.e., joints, muscles, bones).

25

Transdermal patch

A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream. Often, this promotes healing to an injured area of the body.

26

Transduction

The first step in nociception, in which noxious thermal, chemical, or mechanical stimuli are transformed into electrical signals called action potentials.

27

Transmission

The second step in nociception, in which sensory impulses are conducted to the spinal cord.

28

Visceral pain

Pain originating from the internal organs.

29

Wasting

A decrease in body mass, energy, or vigor often caused by disease.

30

Windup

A state, caused by constant nociceptive input from the periphery, in which neurons in the spinal cord become hyperexciteable and sensitive to low-intensity stimuli that would not normally elicit a pain response. Also referred to as Central nervous system hypersensitivity.
