Infective Endocarditis Flashcards
Most common and most virulent
Staphylcocci
Risk Factors of Infective Endocarditis
-Prosthetic cardiac valves or prosthetic material used for cardiac valve repair
-Implanted cardiac devices (pacemaker, implanted cardioverter defibrillator)
-History of bacterial endocarditis
-Congenital Heart Disease
-Cardiac transplant recipients with valvulopathy
-IV drug abuse
-Body piercing
-Hemodialysis
Is a microbial infection of the endothelial surface of the heart
Infective Endocarditis
Clinical Manifestations of Infective Endocarditis
-Fever
-Heart murmur
-Petechial rash
-Osler Nodes
-Janeway lesions
-Roth Spots
-Splinter Hemorrhage
small, painful nodules in pads of fingers or toes
Osler Nodes
irregular, red or purple, painless flat macules on pals, fingers, hands, soles, and toes
Janeway Lesions
Hemorrhages with pale centers in eye fundus
Roth Spots
reddish- brown lines and streaks seen under the proximal half of fingernails and toenails
Splinter Hemorrhage
Alternative medication if allergic to penicillin
Clindamycin or cefalexin
Preventive Management of Infective Endocarditis
-Antibiotic prophylaxis for at risk patients undergoing dental procedure
(Amoxicillin 1 gm 1 hour before procedure)
- Good oral hygiene
-IV site care
-Refrain from using IUDs whenever feasible
-Take antibiotics for the entire duration they are prescribed
Advised patient to:
-Avoid using toothpicks or other sharp objects in the oral cavity
-Avoid nail biting
-Avoid body piercing, branding, tattooing
-Minimize outbreaks of acne, psoriasis
Diagnostics Findings for Infective Endocarditis
-Blood Cultures
-CBC
-Elevated erythrocyte sedimentation rate (ESR) or C-reactive protein
Medical Management
Antibiotic Therapy
-Penicillin (Drug of Choice)
-Must give for 2 to 6 weeks every 4 hours or continuously by IV
-High concentration is needed for a significant period to ensure eradication of the dormant bacteria within dense vegetation
Surgical Management
Indicated if infection does not respond to medications or patient has prosthetic valve endocarditis
Nursing Management of Infective Endocarditis
-Monitor temperature closely
-Administer medications, as ordered
-Educate patient to take medication as prescribed
-Encouraged increased oral fluids
-Promote rest between activities
-Provide meticulous IV site care
-Monitor heart sounds
-Watch out for symptoms of systemic embolization and organ damage
