What is the best concentration of Dakin's solution for odor and bacterial control?

1. 0.5%

2. 0.025%

3. 0.1%

4. 0.0125%

The correct answer is: 0.025%

The best concentration of Dakin's solution for odor and bacterial control is 0.025%. Dakin's solution is a diluted form of sodium hypochlorite, commonly used in wound care for its antimicrobial properties. At this concentration, it effectively reduces bacterial load while being safe for the surrounding tissue. Using a higher concentration can lead to tissue irritation or damage, which is not conducive to healing. This lower concentration strikes a good balance, as it provides sufficient antibacterial activity without compromising the integrity of the wound tissue. Therefore, 0.025% is considered the optimal concentration for achieving both odor control and effective bacterial reduction in wound treatment.
