Document Summary
Cardiovascular system: heart, blood vessels, blood, bloodstream serves as excellent vehicle for the spread of pathogenic organisms, persistent bacteremia (bacteria in blood) is suggestive of intravascular infections such as endocarditis or catheter related infections (life-threatening) Intro: cardio infections can manifest in the heart valves, myocardium, pericardium. Question: based on information so far what diagnosis do you suspect, acute bacterial endocarditis, cap, cellulitis, acute bacterial endocarditis: intravenous users are at an increased risk of vascular-access endocardium). When this bacteria begins to multiply inside the heart, small clumps of bacteria called septic emboli may move into bloodstream spreading to other organs. Patient scenario: anne admitted to hospital and started on antibiotics iv: oxacillin, vancomycin, following day reports show methicillin resistant staphylococcus aureus (mrsa) as result oxacillin was stopped. Bacterial endocarditis: blood specimens are key specimen for diagnosis, blood specimens collected as a set: on aerobic bottle (green), and one anaerobic bottle (pink). In adults 10-20 ml of blood needed per set.
