- 傷口癒合過程可以被分類為四種顏色
- 以臨床照顧而言,以顏色分為四期,黑色及黃色為清創感染期,紅色為養肉期,白(粉紅)色為養皮期
- Cuzzell JZ, The new RYB color code. American Journal of Nursing, 10, 1342-1346.
- 最早沒有分白(粉紅)色,稱為RYB分類系統
-Red: granulation tissue (pink), not all red wounds are healthy....
-Yellow: yellow necrosis, fibrin, exudate, or slough, (whitish yellow, creamy yellow, yellowish green, beige)...
-Black: eschar (necrotic tissue)....
-Pink: proposed by Hellgren and Vincent to classify the wounds at the re-epithelialization stage.
-Other:Arnqvist et al. added another class that contained the undesired reflections in the glossy parts of the wound, which are almost entirely white in the image....
黑色Black
- 黑痂皮在傷口表面,皮膚及皮下組織皆為壞死
黃色Yellow
- 黃色壞死組織,不良的肉芽組織,在痂皮去除後會有膿瘍出現
- 感染的危險性主要由於大量的滲出液
- 壞死組織及不良的肉芽組織已被去除,留下好的肉芽組織
- 在肉芽組織填滿傷口凹陷後,上皮化就在傷口周圍開始
- 這表皮和周圍皮膚比起來是相對較白的
