Pain Management Overview

Study Notes

Pain is defined as an unpleasant, highly personal experience that can affect all aspects of an individual's life, with subjective nature.
Pain management aims to elevate or reduce pain to a comfortable level for the client, even if the initial cause of pain heals.
Types of pain include acute (short-term) and chronic (long-lasting), with different physiological and behavioral responses.
Pain intensity is commonly classified on a scale from 0 (no pain) to 10 (worst possible pain), with mild, moderate, and severe categories.
Pain can be categorized by location, duration (acute or chronic), intensity (mild to severe), and etiology (nociceptic or neuropathic pain).
Nociception is the process of encoding and processing noxious stimuli through specialized sensory receptors called nociceptors.
The Gate Control Theory suggests that the spinal cord contains gates that can block or allow pain signals to reach the brain.
Factors influencing pain perception include cultural values, developmental stages, environmental factors, previous pain experiences, and the meaning of pain.
Accurate pain assessment involves obtaining a pain history, observing behavioral and physiological responses, and using tools like the Wong-Baker Faces Pain Rating Scale.
Nursing diagnoses related to pain include acute pain, chronic pain, ineffective coping, and impaired physical mobility.
Effective pain management strategies include addressing misconceptions, reducing fear and anxiety, and preventing pain through preemptive analgesia.
Pharmacologic pain management includes opioids, non-opioids (NSAIDs, acetaminophen), and co-analgesics (tricyclic antidepressants, anti-convulsants).
The World Health Organization's three-step analgesic ladder provides guidelines for aligning analgesic use with pain intensity, starting from mild pain.- Three-step analgesic ladder by the World Health Organization: non-opioids for mild pain, opioids for moderate pain like hydrocodone, and stronger opioids for severe pain like morphine and fentanyl.
Common side effects of opioids: constipation, nausea, vomiting, sedation, respiratory depression, urinary retention.
Routes of opioid delivery include oral, transnasal, transdermal, rectal, topical, subcutaneous, intramuscular, intravenous, and intraspinal (epidural and intrathecal).
Naloxone (Narcan) is the antidote for opioid overdose and should be readily available for patients receiving opioid-containing epidural infusions.
Patient-controlled analgesia allows patients to self-administer analgesics for pain management, commonly used via the IV route in acute care settings.
Non-pharmacologic pain management strategies include physical modalities (massage, heat/cold therapy, acupressure), cognitive-behavioral interventions (distraction, relaxation response, coping mechanisms), and invasive therapies like nerve blocks.
Immobilization or bracing can help manage acute pain episodes by restricting movement, but prolonged immobilization should be avoided to prevent joint contracture and muscle atrophy.
