At what concentration should Dakin's solution be applied?

1. 0.05% to 0.1%

2. 0.025% or 0.0125%

3. 1.0%

4. 0.1% to 0.2%

The correct answer is: 0.025% or 0.0125%

Dakin's solution is a diluted form of sodium hypochlorite used primarily as an antiseptic for wound care. The appropriate concentration for its application is crucial to maximize antimicrobial effects while minimizing toxicity to the surrounding tissue. The correct concentration for Dakin's solution is indeed at a lower dilution, specifically 0.025% or 0.0125%. These concentrations are effective in providing antimicrobial properties while being gentle enough to avoid cytotoxicity and irritation to the wound bed and surrounding healthy tissue. Higher concentrations, like those found in other choices, can cause significant tissue damage and should be avoided in direct application to wounds. Understanding the specific concentration for application is critical for safe wound management, ensuring a balance between effective infection control and tissue preservation.
