Study Notes
Pain
- Transduction: Injured tissue activates sensory receptors, releasing chemical mediators like prostaglandins, substance P, and bradykinin.
- Transmission: Pain travels through the body in three phases:
- Phase 1: Injury to spinal cord through A-delta and C fibers
- Phase 2: From spinal cord to the brainstem and thalamus
- Phase 3: From the thalamus to the cortex and other structures
- Perception: Pain is consciously experienced in this phase
- Modulation: Signals from the brain travel downwards to dampen pain experience
- Enkephalins, endorphins, serotonin, and noradrenaline are released during this process.
- Pain perception can change based on modulation.
- Gate theory: Explains how pain signals can be facilitated or inhibited
- "Gate" is located in the dorsal horn of the spinal cord
- Activity can either close the gate, reduce pain, or open the gate, increase pain
- Pain terms
- Allodynia: Pain caused by a stimulus that usually does not cause pain
- Analgesia: Absence of pain
- Hyperalgesia: Increased sensitivity to pain
- Paraesthesia: Abnormal sensations of tingling, burning, or numbness
- Pain threshold: The point at which a person starts feeling pain
- Pain tolerance: The level of pain a person can endure
- Pain origins:
- Visceral: Pain originating from organs
- Nociceptive: Pain originating from connective tissue
- Neuropathic: Pain originating from the nervous system
Oncology
- Chemotherapy
- It cannot differentiate between normal cells and malignant cells
- Targets rapidly dividing cells
- Interferes with DNA replication or damages the DNA leading to cell death (apoptosis)
- Neoadjuvant therapy: Treatments administered before the primary cancer treatment
- Adjuvant therapy: Therapy given after the primary treatment
- Chemotherapy drugs
- Classified by cell cycle activity: cell cycle phase specific or cell cycle phase non-specific
- The cell kill hypothesis states that chemotherapy kills a fraction of cancer cells in each treatment
- Radiotherapy
- Uses a controlled dose of radiation to kill or damage cancer cells
- A localized treatment
- Given internally or externally
- Cancer treatment side effects and nursing care considerations
- Include fatigue, nausea, vomiting, hair loss, and bone marrow suppression
Palliative and End of Life care
- Nursing careers in palliative care
- Generalist nurse
- Specialist palliative care nurse
- Clinical nurse specialist palliative care
- Palliative care nurse consultant
- Nurse practitioner palliative care
- Loss, Grief and Bereavement
- Experiences of death, dying, and grief can vary due to individual personality, social variables, culture, religion, and the nature of the relationship with the deceased person.
