Study Notes

Pain Management

Pain can be classified as constant, intermittent, mild, moderate, or severe.
Peripheral nerve fibers form synapses with neurons in the spinal cord, which ascend to the reticular activating system, limbic system, thalamus, and cerebral cortex.

Factors Influencing Pain

Mechanical, chemical, and thermal stimuli can trigger pain.
Psychological factors, such as past experience, depression, and anxiety, can influence pain perception.
Physiological factors, such as age and gender, can also affect pain.
Cultural background can modulate pain perception.

Modulation of Pain

The descending system involves neurons in the brain stem sending signals back down to the dorsal horn of the spinal cord.
Endogenous opioids (endorphins or enkephalins), serotonin, and norepinephrine are involved in pain modulation.

Pain Assessment

Assessing pain involves the client's description of pain, factors that influence pain, and response to pain relief strategies.
Pain assessment scales, such as the Eloisa scale, are used to measure pain.

Physical Assessment

Physical assessment is a systematic way of collecting objective data from a client using four examination techniques.
Transduction, transmission, perception, and modulation are the four stages of pain processing.
Theories of pain include intensity theory, Cartesian theory, specificity theory, and gate control theory.

Types of Pain

Acute pain lasts only through the expected recovery period and does not last longer than six months.
Chronic pain is ongoing and lasts longer than six months.
Cancer pain can be dull, achy, sharp, or burning.
Other types of pain include radiating pain, referred pain, intractable pain, and phantom pain.

Nociceptors and Pain Receptors

Nociceptors are classified into somatic, visceral, and neuropathic receptors.
Noxious stimuli trigger the release of biochemical mediators or algogenic substances, such as bradykinin, prostaglandin, serotonin, histamine, and substance P.

Communication and Assessment

Avoid using leading questions or multiple-choice questions that may confuse the client.
Acknowledge the client's right to express their pain experience.
Nonverbal communication, such as body language and voice tone, is important in pain assessment.
Special considerations, such as gerontologic variations, should be taken into account when assessing pain.
