Catheters

Definition

Catheters are medical devices inserted into the body to drain fluids or administer treatments. They can become a site for microbial growth, potentially leading to infections.

5 Must Know Facts For Your Next Test

1. Catheters can serve as a conduit for bacterial infections, especially in the circulatory and lymphatic systems.
2. Biofilms formed on catheters are resistant to antimicrobial treatments and complicate infection control.
3. Sterilization of catheters is crucial to prevent nosocomial infections.
4. Common pathogens associated with catheter-related infections include Staphylococcus aureus and Pseudomonas aeruginosa.
5. Proper insertion technique and maintenance protocols are essential to minimize the risk of infection.
