What treatment is used for Pseudomonas aeruginosa infections?

The most effective treatment for Pseudomonas aeruginosa infections typically involves antibiotics specifically targeting the bacterium, as this organism is known for its resistance to many common antibiotics. Among the choices provided, the use of topical hydrogen peroxide is prevalent for more superficial infections and helps due to its antiseptic properties. It releases oxygen, which can create an inhospitable environment for anaerobic bacteria, thus potentially providing some benefit against infections.

However, for more serious infections caused by Pseudomonas aeruginosa, systemic antibiotics or a combination of antibiotics are usually implemented. Immediate medical intervention and treatment choice may depend on the site and severity of the infection.

Chloramphenicol and penicillin are less suitable options for Pseudomonas infections due to ineffective results, and while surgery may be indicated in some cases of abscesses or severe infections, it is not a standalone treatment method.
