What stoma color indicates good perfusion and viability?

• A. Pale gray
• B. Dark blue
• C. Pink to bright red
• D. Black

Answer: (C)

A stoma that is pink to bright red shows good arterial blood flow and viable tissue, which means perfusion is adequate and the stoma is likely to heal well. This color reflects proper oxygenation and tissue health, with moisture and a healthy, shiny appearance. In contrast, a pale gray stoma suggests reduced blood flow and possible ischemia; a dark blue stoma indicates venous congestion or insufficient oxygenation; a black stoma signals tissue necrosis. Any discoloration away from pink to red should be reported promptly to the clinician, especially if it persists or worsens, as timely assessment is crucial for preserving stoma viability. In the immediate postoperative period, mild variations can occur, but persistent abnormal color changes require evaluation, and ensure there’s no constriction from dressings or devices impeding perfusion.
