Importance
• Pain management is a primary nursing responsibility
• Nurse have a legal and ethical duty to control/relieve pain
• Pain relief is a basic human right
• Patients need to know we CAN and WILL relieve their pain
![Page 3: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/3.jpg)
NRS_105/320_Collings
Why?
• Effective pain management:– Improves quality of life– Reduces disability– Promotes early mobility and return to work– Results in less hospital / office visits– Reduces length of stay, complications– Reduces health care cost– Improves patient satisfaction

Nature of Pain
• Physical
• Emotional
• Cognitive
• Subjective
![Page 5: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/5.jpg)

Physiology of Pain• Transduction
• Thermal,chemical,mechanical stimulation• → electrical impulse in nerve fiber
• Transmission• A fibers: sharp, localized, distinct sensation• C fibers: generalized, persistent sensation
– E.g. Burn finger – spot pain → ache• Peripheral → spinal → brain
![Page 6: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/6.jpg)
NRS_105/320_Collings
Physiology of Pain
• Perception– Brain interprets impulse, perceives as pain– Experience, memory, context, knowledge– Ascribes meaning to sensation
• Modulation– Body response
• Endogenous opiods, serotonin, norepinephrine, GABA• ↓ transmission of impulse, analgesic effect
– These deplete over time with continued pain
![Page 7: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/7.jpg)
NRS_105/320_Collings
Gate-Control Theory of Pain
• Gating mechanisms along the CNS– Can block transmission of impulses
• Pain relief measures to close the gate– Light touch [effleurage]
• Pain threshold– Level at which you feel pain
• Genetic, learned, • Runner’s high, endogenous opiods• Individual – not transferrable!
![Page 8: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/8.jpg)
NRS_105/320_Collings
Physiological Response to Pain
• Mild – moderate pain [1-6] superficial → autonomic response [sympathetic];
• fight or flight, general adaptation• ↑HR, RR, B/P, BG, diaphoresis, peripheral
vasoconstriction
• Severe or deep [7-10], visceral pain→ parasympathetic response
• ↓ HR, B/P, muscle tension, immobility, irreg resp• may cause harm
– Physiologic response [VS] is short-term; – VS are not reliable pain indicators over time
![Page 9: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/9.jpg)
NRS_105/320_Collings
Behavioral responsesto Pain
• Dependent on context, meaning, culture, pain tolerance– It is supposed to hurt– Men don’t cry– I don’t want to be a complainer, bother
• Nonverbal indicators– Body movements; restless or still, holding, guarding– Facial expression; grimace, frown, clenched teeth, posture,
• Lack of expression of pain does not mean it isn’t there!
![Page 10: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/10.jpg)
NRS_105/320_Collings
Types of Pain
• Acute pain– Protective, identifiable cause, short
duration, limited tissue damage, ↓ emotional response
– Causes harm by ↓ mobility, energy
Goal is to control pain so patient can participate in recovery
↓ Pain → ↑Mobility → decreased complications, decreased length of stay
![Page 11: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/11.jpg)
NRS_105/320_Collings
Types of Pain• Chronic pain
– Serves no purpose [not protective]– Lasts longer than anticipated – May or may not have an identifiable cause– Impacts every part of patient’s life– Depression, Suicide– Disability, isolation, energy drain, ADL’s
• Pseudoaddiction: seeking pain relief– not drug-seeking
![Page 12: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/12.jpg)
NRS_105/320_Collings
Types of Pain
• Cancer pain– May be acute or chronic, constant or episodic,
mild to severe– Up to 90% of Ca pts have pain
• Pain by inferred pathology– Known cause = characteristic pain [neuropathic]
• Idiopathic pain– No known cause BUT still pain– “Excessive” pain for a condition
![Page 13: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/13.jpg)
NRS_105/320_Collings
Knowledge, Attitudes, and Beliefs
• Subjective nature of pain– Pain is what the patient says it is, not
what the nurse thinks it should be– Same procedure, different pain– Expectations, context, culture affect
perception and expression of pain
![Page 14: NRS_105/320_Collings Chapter 43 Pain Management. NRS_105/320_Collings Importance Pain management is a primary nursing responsibility Nurse have a legal.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f175503460f94c2eb6d/html5/thumbnails/14.jpg)
NRS_105/320_Collings
Knowledge, Attitudes, and Beliefs• Nurse’s Response to Pain• Bias
– ‘I go to work with 5/10 pain every day’– ‘Its only a minor surgery’– ‘I had three kids and didn’t scream’
• Fallacies– Infants don’t feel pain like we do– Regular pain med use causes addiction– Older people all are in pain

Planning• Goals and outcomes
– Client is using pain relief measures safely– Pain level reported at </=___ and congruent
nonverbal behaviors seen– Demonstrate understanding of need to
premedicate before activity– Splint abdomen with cough
• Setting priorities– What is important for the client? What does he
need to do? • Control pain enough to eat, sleep? Be mobile to
prevent complications? Work? PT? Maintain dignity, relationships while dying?
– Maslow: Pain relief is basic need

Implementation Pain Management
• Barriers to effective pain management [pts, nurses, doctors, system…]– Fear of addiction - #1 barrier– Terms:
• Dependence: physical adaptation resulting in withdrawal symptoms
• tolerance: physical adaptation resulting in diminished drug effect over time
• Addiction: impaired control over use, use despite harm
• pseudoaddiction: drug seeking behavior to relieve undertreated pain

Implementation Pain Management
• Nursing implications for pain management– Accurate safe medication administration– Assess effectiveness and side effects– Patient education [families too]– Use the appropriate drug when given a
choice– Treat pain before it gets severe

Evaluation• Effectiveness
– Assess at peak of drug effect• [30 minutes IV, 1 hour PO]
– Add complementary therapies for partial effect– Talk with M.D. about options if approach is
consistently ineffective
• Side effects• Document and communicate
– Most effective relief

Evaluation
• Client expectations– Validate experience– Relieve the pain– Show you care
• Did client achieve goal?– Walk hall w/o pain?– Pain < 3/10 all day [except with PT]– Able to return to work, enjoy visit, T,C,&DB?
• Pain report congruent with nonverbal?
