Pain & Comfort

💆‍♀ Pain & Comfort – Week 11 Quick Reference

🔹 Understanding Pain

Definition: An unpleasant sensory + emotional experience associated with actual or potential tissue damage.

Pain is subjective — the client’s report is the most reliable indicator.

Purpose: Protective; signals the body that something is wrong.

🔹 Types of Pain

Acute — Sudden onset, short duration (< 6 months). Activates SNS. Post-op, injury

Chronic (Persistent) — Lasts > 6 months, may be constant/intermittent; affects ADLs, mood. Arthritis, neuropathy

Referred Pain — felt distant from source. Left arm → MI includes other symptoms

Radiating — Extends from origin to adjacent area. Low-back → leg

Phantom — Pain in missing limb. Post-amputation

Neuropathic — Burning, shooting, nerve injury. Diabetic neuropathy

💫 Pain Pathway (Physiology)

1. Transduction: Pain stimulus → electrical impulse.

2. Transmission: Impulse travels via A-delta & C fibers → spinal cord → brain.

3. Perception: Conscious awareness of pain in cerebral cortex.

4. Modulation: Brain sends inhibitory signals (endorphins, serotonin) to reduce pain

🧠 Pain Theories

Gate-Control Theory: Pain impulses can be blocked (“gate closed”) by stimulating larger A-fiber input — massage, heat, TENS unit.

Neuromatrix Theory: Pain perception influenced by genetics, emotions, memory, & stress.

❤ Physiologic & Behavioral Responses

CV — ↑ HR, BP, CO

Respiratory — ↑ RR, shallow breathing

GI — ↓ motility, nausea

Musculoskeletal — Tension, guarding

Emotional — Anxiety, irritability

Chronic — Fatigue, depression, withdrawal

🌿 Factors Affecting Pain

Age (older adults ↑ sensitivity)

Fatigue, anxiety, culture, previous experience

Support systems & meaning of pain

Cognitive level & coping style

✨ Pain Assessment (Nursing Process)

Subjective: Client’s description, 0-10 scale, location, duration, quality, intensity, aggravating/relieving factors.

Objective: Non-verbal cues (grimacing, guarding, ↑ vitals).

Tools:

Numeric Rating Scale (NRS) – adults

Wong-Baker FACES – children > 3 yrs

FLACC – infants/nonverbal clients

PAINAD – dementia

🩺 Nursing Diagnoses

Acute Pain r/t tissue injury AEB verbal reports.

Chronic Pain r/t altered nerve function.

Anxiety r/t anticipation of pain.

Knowledge Deficit r/t pain-management options.

💊 Pharmacologic Key Points

Non-opioid analgesics — Acetaminophen & NSAIDs — Ceiling effect; monitor liver toxicity & GI bleed.

Opioid analgesics — Morphine, hydromorphone, fentanyl — Monitor RR, sedation, constipation; use stool softeners.

Adjuvant meds — Antidepressants, anticonvulsants, local anesthetics — Treat neuropathic pain and enhance analgesia.

Ex: diabetic neuropathy

PCA (Patient-Controlled Analgesia) — IV pump — Only client activates button; monitor sedation score & respiratory status.

Epidural Analgesia — Opioid or local infusion in epidural space — Monitor RR, BP, motor function, catheter site.

🌸 Non-Pharmacologic Pain Management

Relaxation & deep-breathing exercises

Distraction (music, TV, guided imagery)

Massage, heat or cold application

TENS unit (activates A-fibers to “close gate”)

Repositioning, splinting, environment control

Mind-body therapies (yoga, meditation, prayer)

---

🔍 Evaluating Pain Relief

Reassess 30–60 min after analgesic admin (IV 30 min; PO 1 hr). 15 minutes for opioid

Document pain score and client’s verbal response.

Evaluate function and comfort level — not just numeric rating.

⚖ Holistic & Multimodal Care

Combine pharmacologic + non-pharmacologic methods.

Include client preferences, culture, beliefs, and support system.

Promote sleep, nutrition, hydration, and emotional support for optimal healing.

🔔 Special Populations

Older Adults — May underreport pain; start low dose opioids; avoid polypharmacy.

Children — Use age-appropriate tools; involve caregiver; topical anesthetics for procedures.

Cognitively Impaired — Observe non-verbal signs; use PAINAD scale.

Culturally Diverse Clients — Assess beliefs about pain expression and treatment preferences.

💖 Nursing Priorities

1. Believe the client’s report of pain.

2. Prevent pain rather than chase it.

3. Monitor for side effects of analgesics.

4. Promote comfort & restorative sleep.

5. Document assessment & response to interventions

Concept Key Points

Pain Scales

— Numeric (0–10), FACES, FLACC, PAINAD

FACES FOR CHILD/NONVERBAL

PAINAD FOR IMPAIRED COGNITION

FLACC FOR INFANTS

Opioid Antagonist

— Naloxone (Narcan) → reverses respiratory depression

Nonopioid Analgesic

— Acetaminophen Max Dose 3,000–4,000 mg/day

NSAID Risks

— GI bleeding, renal impairment

PCA Safety

— Client-controlled only; no family activation

Sleep & Pain Link

— Poor sleep ↑ pain sensitivity; treat both for comfort

Holistic Measures

— Heat, massage, guided imagery, spiritual care
