| 영문 | decubitus ulcer | 한글 | 욕창 |
|---|---|---|---|
| 설명 | 압박으로 인해서 국소피부의 혈액순환이 감소되고 그것으로 인해서 피부조직이 파괴되는 것을 이르는 말이다. 즉 장기간 피부가 압박받아서 압박을 받은 부위의 혈관이 눌려서 혈류가 감소하고, 그 부분에 공급되는 혈류가 적어서 그 부분이 섞어서 피부의 조직이 없어지는 것을 욕창이라고 한다. 욕창의 호발 부위는 주로 압박을 받기가 쉬운 피부 부위로서 주로 뼈가 튀어나와 있어서 그 뼈로 인해서 쉽게 압력을 받기 쉬운 부위로 무릎, 발뒤꿈치, 엉덩이의 뒷면(엉덩이 뒷면에 뼈가 나온 곳) 등이 있다. 일단 발생한 욕창은 그 상처의 깊이에 따라 5단계로 분류한다. 제1단계는 피부의 압력에 의해서 피부에 적색 발적이나 피부가 단단해지는 정도의 변화를 말하고, 제2단계는 피부의 상층부위에 국한된 표층성 궤양이며, 제3단계는 피부 깊숙이 존재하는 피하지방조직까지 욕창이 침범하였으나 피하 지방층아래에 있는 근육층은 보존된 상태이며, 제4단계는 근육층까지 조직의 결손이 있는 경우이며, 제5단계는 광범위한 욕창이 관절이나 장기가 들어있는 몸속의 공간, 즉 체강까지 침범한 경우이다. |

| ischemic necrosis | Necrosis caused by hypoxia resulting from local deprivation of blood supply, as by infarction. (05 Mar 2000) |

| ischemic neuropathy | Neuropathy resulting from acute or chronic ischemia of the involved nerves. (05 Mar 2000) |
| ischemic optic neuropathy | Optic nerve neuropathy secondary to hypoperfusion of the low pressure posterior ciliary arteries supplying the optic nerve head (nonarteritic) or to temporal arteritis (arteritic). (05 Mar 2000) |
| ischemic preconditioning | A technique in which tissue is rendered resistant to the deleterious effects of prolonged ischemia and reperfusion by prior exposure to brief, repeated periods of vascular occlusion. (am j physiol 1995 may;268(5 pt 2):h2063-7, abstract) (12 Dec 1998) |
| ischemic preconditioning, myocardial | Exposure of myocardial tissue to brief, repeated periods of vascular occlusion in order to render the myocardium resistant to the deleterious effects of ischemia or reperfusion. The period of pre-exposure and the number of times the tissue is exposed to ischemia and reperfusion vary, the average being 3 to 5 minutes. (12 Dec 1998) |
| optic neuropathy, ischemic | A severely blinding disease resulting from loss of the arterial blood supply to the optic nerve as a result of occlusive disorders of the nutrient arteries. Optic neuropathy is divided into anterior, which causes a pale oedema of the optic disk, and posterior, in which the optic disk is not swollen and the abnormality occurs between the globe and the optic chiasm. Ischemic anterior optic neuropathy usually causes a loss of vision that may be sudden or occur over several days; ischemic posterior optic neuropathy is uncommon and the diagnosis depends largely upon exclusion of other causes, chiefly stroke and brain tumour. (12 Dec 1998) |
| transient ischemic attack | A sudden focal loss of neurological function with complete recovery usually within 24 hours; caused by a brief period of inadequate perfusion in a portion of the territory of the carotid or vertebral basilar arteries. (05 Mar 2000) |
| acute decubitus ulcer | A severe form of bedsore, of neutrophic origin, occurring in hemiplegia or paraplegia. (05 Mar 2000) |
| Aden ulcer | The lesion occurring in cutaneous leishmaniasis. (05 Mar 2000) |
| amputating ulcer | An ulcer encircling a limb. (05 Mar 2000) |
| anastomotic ulcer | An ulcer of jejunum, after gastroenterostomy. (05 Mar 2000) |
| anti-ulcer agents | Various agents with different action mechanisms used to treat or ameliorate ulcers or irritation of the gastrointestinal tract. (12 Dec 1998) |
| aphthous ulcer | <gastroenterology> A type of benign mouth ulcer often caused by injury to the mucosal lining of the oral cavity, viral infection or vitamin deficiency. (27 Sep 1997) |
| atonic ulcer | An ulcer that shows little or no tendency to heal. (05 Mar 2000) |
| Buruli ulcer | An ulcer of the skin, with widespread necrosis of subcutaneous fat, due to infection with Mycobacterium ulcerans; occurs in Uganda in persons living on the Nile river banks. Origin: Buruli, district in Uganda (05 Mar 2000) |
