Study Notes

Introduction to Pain

  • The course covers describing, assessing, and managing pain.
  • The Lecturer is from the Psychology Department, School of Medicine.
  • The institution is the RCSI Medical University of Bahrain.

Learning Outcomes

  • Define pain as a complex perceptual phenomenon influenced by biological, psychological, and social factors.
  • Describe the gate-control theory of pain.
  • Outline approaches to pain assessment.
  • Identify major psychological approaches to managing pain.

BMF Case Study (Hip Fracture)

  • Patient Lisa, 80 years old, is living with her husband Joe.
  • Lisa has good health but is having a DEXA scan to assess bone mass.
  • Joe's condition has deteriorated and requires end-of-life care and planning.
  • Lisa is also in need of a more sustainable management plan to meet her health care needs.
  • Lisa fell at home, suffered a significant lower limb injury.
  • The injury prompted hip surgery, which was uncomplicated and successful.
  • Initially, post-surgery rehabilitation was uneventful.
  • Toward the end of rehabilitation, Lisa began experiencing pain in her left knee and lower back (opposite the hip injury side).

Learning Outcome 1: Defining Pain

  • Pain is a complex perceptual phenomenon.
  • Pain is influenced by biological, psychological, and social factors.

What is Pain?

  • Images presented depict a man with his hands over his face and a man experiencing pain from a fire.
  • This suggests a sensory and emotional experience.

The Puzzle of Pain

  • Injury without pain is possible.
  • Pain without injury is also possible.
  • Pain can be disproportionate to the injury.
  • Pain can appear after healing, like phantom limb pain.
  • Multimodal treatments can be successful in managing or alleviating pain.

Definition of Pain

  • Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage.
  • Pain is subjective.
  • Pain involves sensations and emotions.
  • Pain can occur without injury and vice versa.

Pain: An Important Social Issue

  • Prescription drugs are a leading cause of death.
  • The epidemic of arthritis and pain is a significant social issue.

The Cost of Pain

  • Chronic pain affects approximately 20% of the adult European population.
  • Approximately 80% of doctor consultations in the US relate to pain.
  • The prevalence of chronic pain in Ireland is 35.5%.
  • Chronic pain is associated with extended hospital stays and loss of work days, resulting in increased social welfare benefits use.
  • The cost of chronic pain in Europe is estimated at €200 billion annually.
  • The cost of pain in the US is estimated at US560–560–560–635 billion.
  • Current pain statistics underestimate the true human cost.

Acute vs Chronic Pain

  • Acute pain is a useful, adaptive biological response to injury or illness, with a limited duration.
  • Chronic pain persists for six or more months, often not responding well to pharmacological treatment and can be maladaptive.

Learning Outcome 2: Gate Control Theory of Pain

  • Gate control theory describes how pain signals are transmitted and modulated in the nervous system.

Gate Control Theory: Periphery

  • Nociceptors are nerves that transmit pain sensations from the injury site to the spinal gate.
  • A-delta fibers transmit sharp, fast pain related to potential or actual tissue damage.
  • C-polymodal fibers transmit slow, chronic throbbing pain.
  • A-beta fibers are “anti-pain" fibers that transmit touch and pressure sensations, influencing perception of pain.

Gate Control Theory of Pain

  • The image illustrates the different nerve fibers and pathways involved in the gate-control theory.
  • The figure shows A-delta fibers and C-polymodal fibers transmitting pain signals to the spinal cord, while A-beta fibers, which are not shown in the diagram, counteract this pain.
  • This illustrates how pain signals are transmitted through specific nerve pathways in the spinal cord.
  • A-beta fibers are important for modulating the experience of pain.

Gate Control Theory of Pain: Psychological Influences on Pain Perception: Cognition & Mood

  • Mood like anxiety and depression can influence pain tolerance and reporting.
  • Cognitions such as attention can increase or decrease pain according to expectations.

Combined Gate Control Theory Inputs

  • Peripheral pain receptors transmit pain information through nerve pathways in the spinal column.
  • Cognitive and emotional responses to physical damage involve CNS nerve fibers, modifying pain signals by transmitting information up and down the spinal column.

Gate-Control Theory

  • The theory describes how different factors can open or close "gates" in the spinal cord to influence pain perception.
  • High pain has "gates" open, while low pain has "gates" closed.
  • The brain plays a crucial role in this process to influence both brain and spinal cord regions.

Factors that Open or Close the Pain Gate

  • Several factors influence pain perception: Physical factors such as injury or poor physical condition, behavioural factors, and cognitive factors such as focusing on the injury or pain.
  • Other factors contributing to pain perception are emotional factors such as anxiety and depression, and physical factors like appropriate use of medication, heat, cold, and massage.

Learning Outcome 3: Pain Assessment Approaches

  • Pain assessment involves quantifying pain using scales of varying dimensions and intensities.
  • Multidimensional scales, such as the McGill Pain Questionnaire, assess various dimensions of pain.

Learning Outcome 4: Psychological Approaches to Managing Pain

  • Historical goals for pain management included eliminating pain.
  • Modern goals for pain management include reducing pain perception, improving coping mechanisms, increasing functional ability, decreasing reliance on medication, and respecting patient attempts at self-management.

Pain Management - Acute

  • First-line interventions for acute pain are typically pharmacological.
  • Interventions forms and levels include patient-controlled analgesia (PCA).
  • Psychological interventions include teaching coping skills such as distraction, relaxation, and hypnosis.

Pain Management - Acute: Distraction/VR Pain Management

  • Distraction techniques like virtual reality (VR) can help in managing acute pain.

Pain Management - Chronic

  • Chronic pain has causes that are complex and often multifactorial.
  • Various types of gains may be involved: Primary, secondary, and tertiary, which might influence an individual's experience of pain.

Pain Management - Chronic: Results

  • Chronic pain management can lead to negative outcomes, often referred to as the "five D's."

Pain Management (Chronic) - Behavioral and Cognitive Strategies

  • Behavioural strategies, based on operant learning, reinforce adaptive behaviors that help manage pain.
  • Cognitive strategies help patients re-evaluate their thoughts and beliefs surrounding pain, reducing negative experiences.

Pain Management Programmes (PMPs)

  • PMPs are multidisciplinary teams including physicians, nurses, therapists, and other professionals.
  • PMPs integrate treatments and provide the patient with education and support.
  • Patients benefit from a comprehensive assessment, education, training of skills, schedules for exercise and plans for relapse prevention.

Summary

  • Pain perception is influenced by biological, psychological, social, and cultural factors.
  • Gate control theory is a basis for understanding the complexity of pain.
  • Pain is subjective. Pain assessment tools must consider pain as perceived and reported by the patient, in their own context.
  • Effective pain management must include a multidisciplinary perspective.
