Analgesia and Pain Management01:25

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
Pain01:20

Pain

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
Nociception01:44

Nociception

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...
Nursing Assessment01:29

Nursing Assessment

The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments and...

Peripheral Artery Disease IV: Nursing Management

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...

Summary

This study identified seven core dimensions for assessing chronic pain, including pain severity, coping strategies, and emotional distress. These findings help systematically evaluate the multifaceted chronic pain experience.

Area of Science:

  • Pain research
  • Psychometrics
  • Clinical psychology

Background:

  • Existing measures for chronic pain experience lack systematic establishment of relationships between dimensions.
  • Dimensions assessed include pain severity, coping, depression, and activity levels.

Purpose of the Study:

  • To determine the essential dimensions for assessing individuals with chronic pain.
  • To establish a systematic framework for understanding the chronic pain experience.

Main Methods:

  • 126 individuals with chronic pain completed nine validated psychometric measures.
  • Exploratory Factor Analysis (EFA) was used to analyze the relationships between subscales of the nine measures.

Main Results:

  • A seven-factor model demonstrated the best fit for the data.
  • The core dimensions identified were: pain and disability, pain description, affective distress, support, positive coping strategies, negative coping strategies, and activity.

Conclusions:

  • Seven meaningful dimensions of the chronic pain experience were reliably extracted.
  • This provides a systematic approach to assessing chronic pain and informs future research directions.
