- Catheter related blood infections were thought to be caused by skin flora seeding the catheter. Thus, significant effort is applied to sterility and skin preparation.
- However, studies have shown that bacteria growing on the tip of the catheter is not consistent with growth on cultures of skin.
- Staphylococcus epidermidis is commonly found on cultures of catheter sites. It has also been found in the gut flora of >50% of ICU patients. Rates of catheter related blood infections have been decreased through oral decontamination and early feeding.
- These findings suggest enteral bacterial translation as a major source of blood stream infection.
