Pain Management
Comprehensive Nursing Notes
Evidence-Based Pain Assessment and Management Strategies for Nursing Practice
Table of Contents
1. Definition and Overview
Pain management is a multidisciplinary approach to reducing and controlling pain experienced by patients. It encompasses the assessment, diagnosis, and treatment of various types of pain using both pharmacological and non-pharmacological interventions. The goal is to improve quality of life, restore function, and minimize suffering while considering individual patient needs, preferences, and safety.
Key Concept
Pain is considered the “fifth vital sign” and should be assessed and documented with the same frequency and importance as temperature, pulse, respiration, and blood pressure.
Mnemonic: PAIN Assessment
- P – Provocation/Palliation (What makes it better/worse?)
- A – Associated symptoms
- I – Intensity (0-10 scale)
- N – Nature/Quality (sharp, dull, burning, etc.)
2. Pathophysiology of Pain
Pain Pathway Process
Pain Transmission Pathway
Nursing Implementation: Understanding Pathophysiology
- • Educate patients about how pain signals work to improve compliance with treatment
- • Use this knowledge to explain why certain interventions work at different stages
- • Recognize that pain perception is highly individual and influenced by psychological factors
- • Understand that chronic pain may involve changes in the nervous system (neuroplasticity)
3. Types of Pain
By Duration
Acute Pain
Duration: < 3-6 months
Purpose: Protective mechanism
Examples: Post-surgical, trauma, burns
Chronic Pain
Duration: > 3-6 months
Purpose: Often no protective value
Examples: Arthritis, fibromyalgia, neuropathy
By Mechanism
Nociceptive Pain
Source: Tissue damage/inflammation
Quality: Aching, throbbing, sharp
Neuropathic Pain
Source: Nerve damage/dysfunction
Quality: Burning, shooting, tingling
Mixed Pain
Source: Both mechanisms
Example: Lower back pain, cancer pain
Mnemonic: SOCRATES for Pain Assessment
S – Site (Where is the pain?)
O – Onset (When did it start?)
C – Character (What does it feel like?)
R – Radiation (Does it spread?)
A – Associated symptoms
T – Time pattern (Constant/intermittent?)
E – Exacerbating/Relieving factors
S – Severity (0-10 scale)
4. Pain Assessment
Pain Assessment Tools
Numeric Rating Scale (NRS) 0-10
No Pain
Mild
Moderate
Severe
Subjective Assessment
- • Patient’s self-report (gold standard)
- • Location and radiation
- • Quality and character
- • Intensity and severity
- • Timing and duration
- • Aggravating and relieving factors
- • Impact on daily activities
- • Previous pain experiences
Objective Assessment
- • Vital signs changes
- • Facial expressions
- • Body positioning and movement
- • Guarding or protective behaviors
- • Muscle tension
- • Sleep disturbances
- • Appetite changes
- • Social withdrawal
Assessment Principles
Pain is subjective and individual. The patient’s self-report is the most reliable indicator of pain existence and intensity. Believe the patient’s report unless there are clear contraindications.
Nursing Implementation: Pain Assessment
- • Assess pain regularly using standardized tools appropriate for patient population
- • Document location using body diagrams when possible
- • Use appropriate assessment tools for special populations (pediatric, cognitively impaired)
- • Reassess pain after interventions (30 minutes for IV, 60 minutes for PO medications)
- • Consider cultural factors that may influence pain expression
- • Assess pain at rest and with movement/activity
