Study Notes

Introduction to Pain

  • Pain is a complex experience shaped by biological, sociocultural, and psychological factors (genetics, gender, health status, life experience).
  • In 2020, the International Association for the Study of Pain (IASP) defined pain as "unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage."
  • Pain assessment and treatment is challenging because pain experiences vary between individuals and even within the same person.
  • Pain is the number one reason people consult health providers in the US.
  • Treatment success for pain can be mixed, and identifying the cause of pain can be difficult in some cases.
  • Pain has a significant impact on quality of life, disrupting sleep, activity, nutrition, and social interactions. It contributes to anxiety, depression, and loss of independence. The economic cost of pain in the US is estimated at over $100 billion annually.

Definitions of Pain

  • Acute pain: Sudden onset, typically associated with tissue damage, lasting several hours or weeks. It serves a biological purpose, alerting to injury/damage.
  • Chronic pain: Present for more than 3 to 6 months, often not directly linked to tissue damage, unpredictable, and resistant to common treatments.

Distinguishing Pain Types

  • Nociceptive pain: originates in peripheral tissues (skin, muscles, bones, organs) in response to noxious stimuli.
  • Neuropathic pain: originates from damage or dysfunction of the peripheral or central nervous system.

Managing Pain in Older Adults

  • Pain assessment tools used in most healthcare settings may not be reliable or valid in older adults..
  • Older adults may have more complex pain presentations than younger adults (mixed pain).
  • Cognitive impairments are significant barriers to effective pain assessment in older adults.
  • Factors like age, gender, and comorbidities can affect how older adults perceive, describe, and respond to pain.

Patient-Controlled Analgesia (PCA)

  • PCA is a method that allows patients to self-administer medication to manage pain.
  • It can be delivered via IV or subcutaneous infusions.
  • It allows for greater control and minimizes anxiety associated with pain related recovery.

Non-Pharmacological Interventions

  • Positioning: Patients should be positioned comfortably to minimize stress on muscles and joints, reduce pain, and maximize comfort.
  • Heat/Cold: Used for reducing inflammation or pain.
  • Heat can increase blood flow and reduce muscle spasms.
  • Cold can reduce swelling and inflammation in acute injuries.
  • Other Techniques: Massage, relaxation, acupressure, and energy-based therapies (e.g., acupuncture, Reiki). These can often be combined with other measures to maximize comfort and reduce pain.

Pharmacological Treatments

  • Nonopioids: Aspirin, acetaminophen, NSAIDs. These are generally first-line treatments for mild-to-moderate pain.
  • Opioids: Stronger medications used for more severe pain.
  • Corticosteroids: Useful for inflammatory pain conditions, but comes with potential side effects.
  • Other Medications: Include anticonvulsants, tricyclic antidepressants, and selective norepinephrine reuptake inhibitors (SNRIs) which are often employed to treat neuropathic pain.

Other Considerations

  • Cultural factors: Cultural beliefs and practices can influence how patients experience and express pain.
  • Gender and sex: Pain sensitivity and pain perception can differ between genders..
  • Genetics: Genetic variations can affect how individuals respond to pain.
  • Epigenetics: Environmental factors can impact pain, even in people with similar injuries. Understanding a biological context is essential for pain management.
  • Patient education: Patients should be educated on appropriate dosages, use, and side effects of treatment for best outcomes.
