Study Notes
Physical Factors Influencing Pain Experience
- Physical factors that influence the pain experience include pain threshold, pain tolerance, age, physical activity, nervous system integrity, and type of surgery and anesthesia used.
Pain Threshold
- Pain threshold is the point at which a stimulus causes the sensation of pain.
- Anger, fatigue, anxiety, insomnia, depression, and uncontrolled pain lower the pain threshold.
- A lower pain threshold means the person experiences pain more readily with less stimuli.
Pain Tolerance
- Pain tolerance refers to the intensity of pain that a person will endure.
- Pain tolerance varies among patients and for an individual patient, depending on the situation.
- Increasing or prolonged pain may lower the pain tolerance due to fear of non-relief.
Age and Pain Response
- Age influences response to pain, with older patients sometimes not reporting pain or underreporting its severity.
- Reasons for not reporting pain include stoicism, misconception that pain is a normal part of aging, or fear of rejection from caregivers.
Physical Activity and Nervous System Integrity
- Physical activity may aggravate or precipitate pain, but can also be used to relieve pain.
- The integrity of the nervous system affects the response to pain, as it is perceived and interpreted within the system.
Surgery and Anesthesia
- The type of surgery and anesthesia used can influence the response to pain, with surgery on the upper thoracic and abdominal regions thought to be the most painful.
- The type of anesthetic agent used can influence postoperative pain, with some agents providing prolonged analgesia.
- Surgery or invasive procedures may be performed to relieve pain, but pain relief may not be permanent due to nerve tissue regeneration.
- Alternative procedures, such as radio-frequency lesioning and cryoanalgesia, can provide prolonged pain relief.
