| 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. |
