What is a common use of acetic acid in wound care?

1. To promote epithelialization

2. For infections involving pseudomonas

3. To moisturize the wound

4. For pain relief in wounds

The correct answer is: For infections involving pseudomonas

Acetic acid is commonly used in wound care primarily for its antimicrobial properties, particularly in cases where wounds are infected by pseudomonas species. Pseudomonas aeruginosa is a bacteria that can often complicate wound healing, especially in wounds that are chronic or contaminated. The application of acetic acid can help to create an unfavorable environment for these bacteria, effectively reducing the bacterial load and promoting a cleaner wound environment. Acetic acid works by lowering the pH of the wound bed, which can inhibit the growth of certain bacteria, including pseudomonas. This ability to combat specific infections makes it a valuable option in wound management protocols where pseudomonal infection is a concern.
