Study Notes

Pain Terminology Overview

Acute Pain: Follow injury; self-limiting and disappears with healing.
Analgesia: Loss of sensitivity to pain.
Central Sensitization: Increased excitability of spinal cord neurons leading to primary hyperalgesia.
Chronic Pain: Persists for weeks to months beyond expected healing, typically nonmalignant.
Hyperalgesia: Enhanced pain response to normally painful stimuli; involves stimulated nociceptors.
Local Anesthesia: Temporary sensation loss in a localized area without affecting consciousness.

Pain Management Techniques

Multimodal Anesthesia: Involves multiple drugs acting at various nociceptive pathway levels for optimal pain relief.
Nociception: Physiological process of receiving and processing pain signals from nociceptors.
Perception of Pain: Conscious emotional experience of pain, integrating nociceptor and other CNS inputs.

Pain Characteristics

Pain: Unpleasant sensory and emotional experience related to actual or potential tissue damage.
Pain Threshold: Minimum level of pain perceived by an individual.
Pain Tolerance Level: Maximum pain intensity that an individual can endure.

Types of Pain

Pathologic Pain: Exaggerated pain response beyond protective utility, associated with tissue injury.
Physiologic Pain: Protective pain mechanism that encourages avoidance of further tissue damage.
Peripheral Sensitization: Increased neuron excitability in damaged tissue, contributing to localized hyperalgesia.
Somatic Pain: Originates from skin, muscles, joints; characterized as sharp or throbbing.
Visceral Pain: Arises from organ distention or inflammation; described as deep or cramping without clear localization.

Pain Modulation Mechanisms

Preemptive Analgesia: Administration of pain relief drugs before potential pain stimuli to prevent sensitization.
Regional Anesthesia: Loss of sensation in a specific body area by disrupting sensory nerve conduction.
Tolerance: Decreased intensity of analgesic effects over time, requiring higher doses to achieve relief.
Windup: Sensitization of nociceptors and pain pathways resulting from repeated nociceptive input, leading to increased pain response.
