[Intraoperative staining of tissues].

Area of Science:

• Surgical Innovation
• Medical Diagnostics
• Tissue Viability Assessment

Background:

• Distinguishing between blood-supplied and non-blood-supplied tissues is critical in traumatology, reconstructive, and septic surgery.
• Chronic and septic conditions often present challenges in identifying necrotic bone and soft tissues, leading to prolonged inflammation and fistulas.
• Vital tissue dyeing offers a potential solution for precise surgical debridement and treatment planning.

Observation:

• Disulphine Blue, a vital dye introduced by K. Klemm, has been utilized for surgical treatment of septic bone necrosis.
• The dye is administered intravenously, resulting in a temporary green discoloration of the skin and conjunctiva.
• Disulphine Blue aids in the visual differentiation of normal, blood-supplied tissues from necrotic tissues.

Findings:

• The study investigates the application of Disulphine Blue for assessing tissue viability.
• A case report details the use of Disulphine Blue in a patient with chronic inflammation and purulent fistulas following Achilles tendon rupture and repair.
• The dye facilitated the identification of necrotic tissue, guiding surgical intervention.

Implications:

• Vital dyeing with Disulphine Blue can significantly enhance surgical precision in cases of tissue necrosis.
• This technique holds promise for improving outcomes in reconstructive surgery, burn treatment, and management of bone and soft tissue infections.
• Accurate assessment of tissue vitality can reduce complications and expedite patient recovery.
