Document Summary
Increased infection risk with insertions such as prostheses (e. g. artificial joints,) pacemakers, Usually a part of the normal skin flora. Staphylococcus epidermidis ( produces a capsule, gluing itself to the device) Staphylococcus aureus ( most common cause of skin infections) Infections of vascular grafts e. g. cabg (coronary artery bypass graft), where they take a vein from a different part of the body and place it around the heart result from: 1: extension from adjacent infected tissue, hematogenous seeding (s. aureus most common pathogen) 1: hub (plastic bit in the middle of iv line, sits above skin) 3: hematogenous feeding from a distant site. Used to remove toxic wastes from those with renal failure. Intravenous or hemodialysis" viruses can filter through and hang around in dialysis machine, causing infection to next patient: peritoneal dialysis, have permanent port , drain all fluid out first, prefuse with new fluid, wait 5 hours, then drain.
