Chapter 9: Pain Management

Pain Management video summary provides a comprehensive review of pain management nursing, emphasizing that pain is a complex, subjective experience defined entirely by the patient's self-report. The content distinguishes between acute pain, which is typically short-term and related to tissue damage, and chronic or persistent pain, which is categorized into cancer and noncancer origins. A significant portion is dedicated to the physiology of nociception, detailing the four processes of transduction, transmission (involving A-delta and C fibers), perception, and modulation, while contrasting this with neuropathic pain mechanisms such as central and peripheral sensitization, neuroplasticity, allodynia, and hyperalgesia. The nursing process is applied through comprehensive pain assessment strategies, utilizing validated tools like the Numeric Rating Scale (NRS), Wong-Baker FACES, and the Critical Care Pain Observation Tool (CPOT), and applying the Hierarchy of Pain Measures for nonverbal patients. Pharmacologic interventions are explored through the framework of multimodal analgesia, which combines different drug classes to maximize efficacy and minimize side effects. Detailed descriptions are provided for nonopioid agents like acetaminophen and NSAIDs (including COX-1 and COX-2 inhibition risks), and opioid analgesics such as morphine, fentanyl, and hydromorphone. Critical concepts regarding opioid therapy are clarified, including the differences between physical dependence, tolerance, and substance use disorder (SUD), as well as the phenomenon of opioid-induced hyperalgesia. The summary also addresses the management of adverse effects like respiratory depression and sedation using the Pasero Opioid-Induced Sedation Scale (POSS), and the role of co-analgesic agents or adjuvants like anticonvulsants (gabapentin), antidepressants (TCAs, SNRIs), and local anesthetics. Finally, nonpharmacologic therapies, gerontologic considerations for safe dosing, and the ethical prohibition against using placebos for pain assessment are examined to ensure holistic patient care.
