Final answer:
A single 2-stage venous cannula may decrease the risk of catheter-related bloodstream infections by reducing the number of insertion points, potentially lowering the incidents of CRBSIs reported each year.
Step-by-step explanation:
The use of a single 2-stage venous cannula in medical procedures offers the advantage of potentially reducing the risk of catheter-related bloodstream infections (CRBSIs). Venous catheters are crucial devices for patients who need long-term administration of medications or fluids. However, the presence of these devices increases the risk of bloodstream infections, which are significant contributors to morbidity and mortality in the medical field. The World Health Organization reports that up to 80,000 CRBSIs occur annually in the United States, leading to approximately 20,000 deaths. By utilizing a single 2-stage venous cannula, there is a potential for fewer insertion points, which could decrease the probability of infection.
