Non-Pharmacological Pain Management
Overview
Non-pharmacological pain management uses physical, cognitive-behavioral, and environmental measures the nurse can initiate independently. They work by gate control theory — non-painful sensory input closes spinal 'gates' to pain signals — and by lowering sympathetic activation (heart rate, blood pressure, muscle tension). They are adjuncts that complement, never replace, adequate pharmacologic analgesia in a multimodal plan, and have few side effects.
Indications
Technique
Heat vs Cold — physiologic effect and best use
Heat
- Vascular effect
- Vasodilation, increased blood flow
- Best use
- Chronic stiffness, muscle spasm
- Timing
- Ongoing chronic pain
- Skin barrier
- Cloth barrier, never direct
- Duration limit
- 20 minutes
- Key caution
- Avoid on impaired sensation — burn risk
Cold
- Vascular effect
- Vasoconstriction, slowed nerve conduction
- Best use
- Acute injury, swelling, inflammation
- Timing
- First 24-48 h after injury
- Skin barrier
- Cloth barrier, never direct
- Duration limit
- 20 minutes
- Key caution
- No continuous use — tissue damage, rebound
Interpretation
Patient Teaching
Clinical Pearl
Cold for fresh injury and swelling, heat for stiffness — barrier the skin, cap it at 20 minutes, and gate before you escalate. Never put heat on a neuropathic limb.
