Bacterial endocarditis in the critically ill surgical patient

Area of Science:

• Infectious Diseases
• Cardiology
• Critical Care Medicine

Background:

• Endocarditis is a serious infection affecting heart valves.
• Right-sided heart catheters, including Swan-Ganz and central venous catheters, are commonly used in critically ill patients.
• Persistent intraperitoneal sepsis presents a significant challenge in managing critically ill patients.

Observation:

• A study identified four (27%) of 15 endocarditis patients with persistent intraperitoneal sepsis and right-sided heart catheterization.
• These patients experienced intra-abdominal abscesses, documented septicemia, long-term catheter use, and prolonged hospitalization.
• Endocarditis with persistent septicemia was a major factor in the fatal outcomes observed.

Findings:

• A new cardiac murmur associated with septicemia was the most reliable diagnostic indicator.
• The study highlights a significant association between endocarditis, persistent sepsis, and right-sided heart catheterization.
• These complex cases often resulted in fatal outcomes.

Implications:

• Prevention strategies are crucial, including eliminating septic foci and judicious use of central catheters.
• Prompt discontinuation of catheters upon suspicion of septicemia is recommended.
• Early diagnosis through monitoring for new cardiac murmurs in septic patients is vital for timely intervention.
