Study Notes
Pain Perception and Transmission
- Substances like endorphins and gamma-aminobutyric acid (GABA) can change or inhibit pain perception
- Pain impulse transmission may be reduced by non-pain impulses (e.g., ice, massage) competing to transmit sensations along the same spinal pathways to the brain
- Response to pain is individualized due to physiologic, behavioral, and emotional factors
- Factors affecting pain perception: emotions, cultural background, sleep deprivation, previous pain experience, and age
Infants and Pain
- Infants are more susceptible to hypothermia due to large body surface area, thinner skin, inability to shiver, and limited ability to cope with cold stress
- Infants have higher pulse and respiratory rates than adults, decreasing as the child ages
- Infants have lower blood pressure than adults, increasing as the child ages
- Nociceptor system for pain processing develops early in fetal life, enabling preterm and full-term newborns to feel pain
- Immaturity of the neurologic system results in differences in pain transmission and processing
- Most pain impulses are transmitted along unmyelinated slower C fibers
- Infants are less able to modify pain impulses due to immature dorsal horn synaptic connection and inhibition circuits
Pregnant Patients and Pain
- Blood pressure decreases due to lowered systemic vascular resistance starting at 8 weeks' gestation
- Diastolic value decreases more than systolic value, gradually rising to pre-pregnancy levels by term
- Pain may be caused by several physiologic processes:
- Back pain due to lax ligaments, weight gain, and hyperlordosis
- Cramping or pressure related to premature labor or Braxton Hicks contractions
- Epigastric pain due to pressure from the gravid uterus
- Round ligament pain due to stretching of ligaments by the enlarging uterus
- Pressure on the bladder due to the weight of the enlarging uterus
Older Adults and Pain
- No evidence suggests that older adults have a diminished perception of pain
- Some older adults may have an increased pain threshold or less pain tolerance due to peripheral neuropathies, thickened skin, or cognitive impairment
- Many older adults have chronic health conditions associated with pain, such as arthritis, osteoporosis, or peripheral neuropathy### Vital Signs and Pain Assessment
- Vital signs include assessment of temperature, pulse, respiration, and blood pressure
- Pain assessment is considered the fifth vital sign
- Pain is a subjective unpleasant symptom of many conditions and injuries
- The pain experience, its characteristics, and intensity are unique for each person
Anatomy and Physiology of Temperature
- Body temperature is regulated and maintained by the hypothalamus
- When pathogens invade the body, exogenous pyrogens are released and travel to the hypothalamus
- Pyrogenic cytokines are produced, leading to production of prostaglandin E2
- The hypothalamus raises the body's temperature set point, stimulating heat production and a fever (pyrexia)
- Release of epinephrine and norepinephrine increases heat production by raising the basal metabolic rate
Anatomy and Physiology of Pulse Rate
- The arterial pulse results from ventricular heart contraction, pushing a pressure wave of blood throughout the arterial system
Anatomy and Physiology of Respiratory Rate
- The primary muscles of respiration are the diaphragm and intercostal muscles
- The diaphragm is the dominant muscle, contracting and moving downward during inspiration to increase intrathoracic space
- The external intercostal muscles increase the anteroposterior chest diameter during inspiration
- The internal intercostal muscles decrease the lateral diameter during expiration
Anatomy and Physiology of Blood Pressure
- Arterial blood pressure is the force of the blood against the wall of an artery when the ventricles of the heart contract and relax
- Systolic pressure is the force exerted when the ventricles contract
- Diastolic pressure is the force exerted by peripheral vascular resistance when the heart is in the filling or relaxed state
- Blood pressure is highest during systole and falls to the lowest point during diastole
Pain
- Acute pain is of short duration and has a sudden onset in association with injury, surgery, or an acute illness episode
- Persistent (chronic) pain lasts several months or longer and is often sustained by a pathophysiologic process
- Neuropathic pain is long-term pain associated with damage or dysfunction of the central or peripheral nervous system
- Nociceptors are free nerve endings in the peripheral nervous system activated by tissue damage from injury or inflammation
Transmission of Pain Impulses
-
Pain impulses travel from the site of tissue damage to the dorsal horn of the spinal cord through the ascending spinal tracts to the thalamus and cerebral cortex
-
Two specialized nerve fibers transmit pain impulses (nociception) to the dorsal horn of the spinal cord
-
Sharp, well-localized pain is quickly transmitted by the large, myelinated A-delta fibers
-
Dull, burning, diffuse, and chronic pain is slowly transmitted by the small, unmyelinated C fibers### Thermoregulation
-
Increased muscle tone and shivering produce heat through rapid contraction and relaxation of skeletal muscles.
-
Vasoconstriction helps conserve heat by reducing heat loss through the skin.
-
Body cooling occurs through radiation, vasodilation, conduction, convection, evaporation, decreased muscle tone, and increased respiratory rate.
Pulse Rate
- The arterial pulse results from ventricular heart contraction pushing a pressure wave of blood throughout the arterial system.
- The pulse rate is a measure of the heart's contraction and relaxation.
Respiratory Rate
- The primary muscles of respiration are the diaphragm and intercostal muscles.
- The diaphragm is the dominant muscle, contracting and moving downward during inspiration to increase intrathoracic space.
- The intercostal muscles increase the anteroposterior chest diameter during inspiration and decrease the lateral diameter during expiration.
- Air is drawn into the lungs during inspiration and expelled during expiration when the intercostal muscles and diaphragm relax.
Blood Pressure
- Arterial blood pressure is the force of blood against the artery wall as the ventricles contract and relax.
- Systolic pressure is the force exerted when the ventricles contract, influenced by cardiac output, blood volume, and artery compliance.
- Diastolic pressure is the force exerted by peripheral vascular resistance when the heart is in the filling or relaxed state.
- Pulse pressure is the difference between systolic and diastolic pressures.
Pain
- Pain is an uncomfortable sensation and emotional experience associated with actual or potential tissue damage.
- Acute pain is of short duration, with a sudden onset, often associated with injury, surgery, or acute illness.
- Persistent (chronic) pain lasts several months or longer and is often sustained by a pathophysiologic process.
- Neuropathic pain is long-term pain associated with damage or dysfunction of the central or peripheral nervous system.
- Nociceptors are free nerve endings in the peripheral nervous system activated by tissue damage or inflammation.
- Biochemical mediators facilitate the transmission of pain impulses from nerve endings along nerve pathways.
- Pain impulses travel from the site of tissue damage to the dorsal horn of the spinal cord through the ascending spinal tracts to the thalamus and cerebral cortex.
- Two specialized nerve fibers transmit pain impulses (nociception) to the dorsal horn of the spinal cord: A-delta (Aδ) fibers for sharp, well-localized pain and C fibers for dull, burning, diffuse, and chronic pain.
