Study Notes

Pain Management

Pain is a subjective experience defined as "whatever the experiencing person says it is, existing whenever he says it does"
Pain is a primary reason people seek healthcare and a common condition treated by nurses
Unrelieved pain can affect all body systems and cause harmful effects, potentially lasting a lifetime
Harmful effects of unrelieved pain include impacts on endocrine, metabolic, cardiovascular, respiratory, genitourinary, gastrointestinal, musculoskeletal, immune, cognitive, developmental, and future quality of life
Types of pain include: acute or chronic, and nociceptive (physiologic) or neuropathic (pathophysiologic)
- Nociceptive pain is the result of normal functioning of physiologic systems, often in response to noxious stimuli (tissue damage) and is usually described as aching or throbbing, localized pain
- Neuropathic pain involves abnormal processing of sensory input within the nervous system, may be peripheral or centrally generated, and often involves symptoms of unusual or constant pain
Acute pain lasts less than a month, often from injury or illness, and features pain, bruising, swelling, loss of function; PRN or therapy schedule based on short-term need
Chronic pain lasts longer than a month, may be from cancer or other sources, and is marked by functional impairment, progression of symptoms, and requiring scheduled and PRN therapy
Nociceptive pain includes visceral pain from internal organs (e.g., the GI tract and pancreas) and somatic pain from bone, joint, muscle, skin or connective tissue (e.g., aching, throbbing, localized pain)

Pain Assessment

Pain assessment should be comprehensive with attention to location, intensity, quality, onset & duration, aggravating & relieving factors, and effect on function & quality of life.
Assessment tools include the:
- Numeric Rating Scale (NRS): 0-10 point rating scale
- Wong-Baker FACES Pain Rating Scale: faces to represent pain level
- Verbal Descriptor Scale (VDS): words to describe pain intensity
- Visual Analog Scale (VAS): 10-cm line anchored with "no pain" and "pain as bad" endpoints
Pain assessment should be applied during the admission assessment, initial interview with the patient, with every new report of pain, with changes in patient condition, and changes in treatment plan.
Pain should be reassessed immediately after the intervention.

Pain Process

Transmission is the second process in nociception; generation of action potential along A-delta & C-fibers.
Transmission involves passing information through the dorsal root ganglia and synapses in spinal cord's dorsal horn
In perception, higher brain structures become involved initiating awareness, emotions associated with pain.
Modulation is the final process where information about pain is regulated from the periphery to the cortex involving various neurochemicals

Pharmacological Management of Pain

Multimodal analgesia is a recommended approach to treating different types of pain in all age groups.
It combines drugs with different mechanisms to reduce adverse effects.

Routes of Administration

Oral route is the preferred
Intravenous route preferred post-op
Rectal for alternative when oral or IV is not possible
Topical pain management is used for both acute and chronic pain
Epidural analgesia is administered by clinicians

Dosing Regimen

Effective pain management aims to prevent pain and maintain pain intensity allowing quality-of-life goals
Scheduled ATC dosing of analgesics is used for stable or persistent pain
Patients with recurring pain may need to be awakened.
PRN administration is also appropriate for intermittent pain.

Patient-Controlled Analgesia (PCA)

PCA allows patients to administer their own medication.
PCA can be administered via different approaches, including oral, IV, subcutaneous, epidural, and perineural
Close monitoring by nurses is key to prevent complications from sedation.

Analgesic Agents

Analgesic agents include:
- Nonopioids: acetaminophen and NSAIDs (for mild to moderate pain)
- Opioids: morphine, hydromorphone, fentanyl (for moderate to severe pain)
- Adjuvants: antidepressants, anticonvulsants, corticosteroids (to enhance opioid effects)
Opioid analgesics interact with opioid receptors in peripheral tissues, the GI system and the CNS, particularly in the dorsal horn of the spinal cord
Opioid antagonists can reverse adverse effects such as respiratory depression
Opioids' adverse effects include constipation, nausea, vomiting, itching, and sedation,
Effective dosage may be titrated based on the degree of patient's tolerance and the progression of the pain
Dependence and Tolerance are normal responses to repeated administration and are to be considered by management plan

Co-Analgesic Medications

Co-analgesic medications are used primarily for neuropathic pain
Therapy frequently includes low initial doses with gradual increase to allow tolerance for adverse effects

Nonpharmacological Methods of Pain Management

Non-pharmacological methods include physical modalities (e.g., heat, cold, massage) and Cognitive & behavioral methods like relaxation breathing, distraction, imagery, rhythm, tapping and humor.
Other non-pharmacological methods also include movement therapy (yoga, Tai Chi), biologically based therapies (herbs, vitamins, proteins, aromatherapy, diet modifications) and energy-based therapies like therapeutic touch, Reiki and healing touch.

Nursing Implications of Pain Management

Nurses perform thorough pain assessments.
Administering analgesics as prescribed.
Nurses educate patients about pain relief methods.
Assess pain level and any adverse effects.
Educate about prescribed pain management plan.
Obtain additional prescriptions and/or adjustments as needed
