Study Notes
Pain Pathways
- Pain is a subjective experience associated with tissue damage.
- The International Association for the Study of Pain defines pain as an unpleasant sensory and emotional experience.
- Pain involves a complex interaction of the ascending and descending nervous systems.
- Pain perception involves sensory, motivational, and cognitive levels.
Historical Definitions of Pain
- Aristotle considered pain as a feeling processed in the heart.
- Descartes, Galen, and Vesalius linked pain to brain processes.
- 19th-century physiologists identified sensory receptors and nociceptors.
Epidemiology of Pain
- Millions experience chronic pain in the US.
- Acute pain from injury or surgery is common.
Categories of Pain
- Nociceptive pain (somatic and visceral): originating from injury or tissue damage.
- Neuropathic pain (nerve damage or dysfunction).
- Inflammatory pain (inflammation).
- Psychogenic pain (psychological factors).
- Referred pain (pain felt in a location distant from the source).
- Phantom pain (pain felt in a limb that is no longer present).
Acute Pain
- Rapid onset, often associated with tissue damage.
- Usually brief and resolves with appropriate treatment.
Chronic Pain
- Persistent or recurring pain lasting three or more months.
- Often more complex to treat.
Pain Theories
- Specificity theory: distinct receptors and pathways transmit pain signals.
- Pattern theory: different patterns of neuronal activity distinguish pain and non-pain sensations.
- Neuromatrix theory: the brain plays a critical role in pain through a neural network (called the neuromatrix) integrating sensory, emotional, and cognitive factors to create the subjective experience of pain.
- Gate control theory: spinal cord mechanisms modulate pain signals.
Endogenous Analgesic Mechanisms
- The body produces its own opioid-like substances that can block or suppress pain signals.
Pain Pathways
- Pain signals travel through specific pathways from the periphery to the brain. These include A-beta fibres, A-delta fibres, and C fibres.
Third Order Neurons
- Neurons within the thalamus and reticular formation transmit pain signals to the cerebral cortex and areas dealing with emotions.
Ascending & Descending Pain Pathways
- Ascending pathways carry pain information from the periphery to higher brain centres.
- Descending pathways carry signals from the brain to influence pain perception in the spinal cord.
Pain Management Strategies
- Non-pharmacological (physiotherapy, relaxation techniques, psychological support)
- Pharmacological (opioids, nonopioids, adjuvant analgesics)
- Surgical approaches (cordotomy, rhizotomy).
Treatment Modalities
- Surgery
- Radiation therapy
- Chemotherapy
- Immunotherapy/Biologic Therapy
- Molecularly targeted therapy
Clinical Presentation of Pain
- Includes acute and chronic pain presentations.
- A thorough history, physical exam, and diagnostic tests are necessary.
Pain Assessment Tools
- Rating scales (verbal, numerical)
- Multi-dimensional assessment scales (McGill pain questionnaire).
Specific Cancer Pain
- Includes types of cancer, symptoms, and treatment options.
Types of Radiotherapy
- External radiation (teletherapy, intensity modulated RT)
- Internal radiation (brachytherapy, systemic internal radiation)
Effects of Radiotherapy
- Short-term and long-term effects on tissues and organs.
- Requires careful patient monitoring and management to alleviate symptoms.
Adverse Effects of Chemotherapy
- Includes common side effects of the treatment.
- Proper management includes early identification of the adverse effects and initiating the necessary actions to minimize the effects.
Management of Pain
- Needs a comprehensive approach including pharmacological and non-pharmacological interventions
Medical Management of Pain
- Requires a holistic approach encompassing both pharmacological and non-pharmacological considerations.
Tumor Lysis Syndrome (TLS)
- This describes a rapid breakdown of malignant tumor cells when undergoing aggressive therapies that can release metabolic products into the bloodstream.
