What risk is significantly increased by the use of catheters?

The significant increase in the risk of infection when using catheters is primarily due to the direct access that catheters provide to the bloodstream or other body cavities. Catheters can serve as a pathway for microorganisms to enter the body, especially when they are inserted for extended periods of time. This can lead to catheter-associated infections, including bloodstream infections, urinary tract infections, and localized infections at the insertion site.

The risk of infection is heightened in cases where sterility is not maintained during catheter insertion or management, as well as in situations where the catheter is not regularly monitored and appropriately cared for. The presence of a foreign body, such as a catheter, disrupts the natural barrier that the skin typically provides against pathogens, making it easier for infections to occur.

Understanding this risk is essential for healthcare practitioners, as it highlights the importance of adhering to strict aseptic techniques during catheter insertion and maintenance, as well as implementing regular monitoring and protocols to minimize infection risk.
