Chronic wound pain is a condition described as unremitting, disabling, and recalcitrant pain experienced by individuals with various types of chronic wounds.〔Sibbald, R. G. (1998). Venous leg ulcers. Ostomy/wound management, 44(9), 52-64〕 Chronic wounds such as venous leg ulcers, arterial ulcers, diabetic foot ulcers, pressure ulcers, and malignant wounds can have an enormous impact on an individual’s quality of life with pain being one of the most distressing symptoms.〔Coutts, P., Woo, K. Y., & Bourque, S. (2008). Treating patients with painful chronic wounds. Nursing Standard, 23(10), 42-46.〕〔Price, P., Fogh, K., Glynn, C., Krasner, D. L., Osterbrink, J., & Sibbald, R. G. (2007). Managing painful chronic wounds: the wound pain Management Model. International Wound Journal, 4(s1), 4-15.〕〔Woo, K., Sibbald, G., Fogh, K., Glynn, C., Krasner, D., Leaper, D., ... & Teot, L. (2008). Assessment and management of persistent (chronic) and total wound pain. International wound journal, 5(2), 205-215〕〔Briggs, M., Collinson, M., Wilson, L., Rivers, C. McGinnis, E. Dealey, C. Brown, J., Coleman, S., Stubbs, N., Stevenson, R., Nelson, E., Nixon, J. (2013). The Prevalence of pain at pressure areas and pressure ulcers in hospitalized patients, BioMed Central Nursing, December 2013; 12(19). doi:10.1186/1472-6955-12-19〕 The pain experienced by individuals with chronic wounds can be acute or chronic. Acute wound pain is intermittent and exacerbated by manipulation of the wound during procedures such as dressing changes or debridement. Chronic wound pain is present for six months or more and occurs without any manipulation of the wound. Chronic wound pain is persistent and exists at rest.〔〔Soon, K., & Acton, C. (2006). Pain-induced stress: a barrier to wound healing. WOUNDS UK, 2(4), 92.〕 Persistent pain is used interchangeably or to replace the term chronic pain.〔 Intermittent or continuous pain that is present for three months or more is considered as persistent pain. Persistent pain is also referred to as neuropathic pain.〔Sussman, C., & Bates-Jensen, B. (2007). Management of wound pain. Wound Care: A Collaborative Practice Manual for Health Professionals. 3rd ed. Philadelphia, PA: Lippincott Williams & Wilkins.〕 Depending on the sensation associated with neuropathic pain, it may be considered as acute or chronic. Acute neuropathic pain is associated with burning, squeezing, throbbing, shooting, or electric shock sensations that resolve. Neuropathic sensations such as numbness, tingling, and prickling are considered as chronic neuropathic pain. Chronic neuropathic pain may be intermittent or continuous, and may remain unresolved post tissue healing.〔 == Classifications of wound pain == ''Nociceptive'' pain is a physiological response described as stabbing, throbbing, aching, or sharp. Nociceptive pain is considered to be an appropriate to painful stimuli that occurs as a result from underlying tissue damage and may be acute or chronic. Nociceptive pain that is persistent may due to conditions causing ongoing tissue damage such as ischemia, or edema.〔 ''Neuropathic'' pain is associated with chronic pain and results from a nervous system dysfunction, which causes an inappropriate response to pain.〔 Neuropathic pain is described as burning or tingling persistent pain.〔 Three types of nociceptive pain are experienced with chronic wounds; ''cyclic acute wound pain'', ''non cyclic acute wound pain'', and ''chronic wound pain''.〔Krasner, D. (1995). The chronic wound pain experience: a conceptual model. Ostomy/wound management, 41(3), 20-25.〕 Cyclic acute wound pain may be experienced in conjunction with chronic wound pain and occurs during regular routines such as dressing changes or repositioning. Noncyclic acute wound pain is intermittent and usually occurs during procedures such as sharp debridement.〔〔 Chronic wound pain is described as acute or chronic. Acute pain is nociceptive pain that serves as a warning to prevent mechanical, chemical, and thermal injuries. Acute pain is relieved when the damaging source is reduced. Chronic pain has physical and emotional components and is rarely an indication of ongoing damage.〔〔 In order to effectively manage wound pain, the type of wound pain must be determined to facilitate pain relief. Neuropathic pain may require different interventions and medications than the traditional analgesics, which are effective in the treatment of nociceptive pain. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chronic wound pain」の詳細全文を読む スポンサード リンク
