Study Notes
Pathophysiology of Pain
- Pain is a complex process with four stages: transduction, transmission, perception, and modulation.
- Transduction: A stimulus (e.g., pressure, chemical irritation) is converted into a nerve signal by nociceptors.
- Transmission: Sensory nerve cells send pain signals to the brain and spinal cord.
- Chemicals like serotonin, prostaglandins, and bradykinin are released in response to tissue injury, triggering the inflammatory response and creating pain.
- The transmission of pain impulses is processed in the spinal cord and brain.
- Myelinated nerve fibers (A delta fibers) transmit sharp, fast pain signals.
- Unmyelinated nerve fibers (C fibers) transmit dull, slow, throbbing pain.
Perception of Pain
- Perception involves integrating sensory messages, creating a coherent pain experience.
- Pain threshold varies between individuals.
- Pain tolerance refers to the degree of pain an individual can bear.
- Pain expression is how an individual communicates pain experience to others.
Modulation of Pain
- This process involves adjusting or regulating pain perception in the central nervous system.
- It can amplify or dampen pain signals.
- The spinal cord plays a key role in modulating pain signals(dorsal horn).
Definitions of Pain
- Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage.
- Pain is what the experiencing person says it is.
Types of Pain: Acute
- Short-lived pain, warning the body of injury.
- Causes include fractures, burns, surgery, and ischemic pain (e.g., post-operative).
Types of Pain: Chronic
- Pain lasting 6 months or longer.
- Symptoms may include lack of sleep, fatigue, irritability, and severe pain.
- Narcotics are not consistently recommended for long-term management and can cause dependency.
- Depression is often associated with chronic pain.
Somatic Pain
- Well-localized pain directly related to the body's tissues.
- Pain experience can be sharp, stabbing, throbbing
Visceral Pain
- Pain originating from organs.
- Example symptoms like deep cramping or sharp/ stabbing pain.
Neuropathic Pain
- Experiencing shock or nerve pain (e.g., phantom limb).
Kidney Pain
- Kidney stones can cause sharp or dull pain as they move through the renal system.
- Lower back pain may indicate kidney pain.
- Kidney function is also important to analyze.
