AAE Guidance on Antibiotic Prophylaxis (AP)

Flashcards covering definitions, dosage regimens, and clinical guidelines for antibiotic prophylaxis in patients with heart conditions or prosthetic joint implants as per AAE and AHA/ADA standards.

Antibiotic prophylaxis (AP)

The administration of antibiotics to patients without signs of infection to reduce subsequent postoperative or post-treatment complications by preventing bacterial colonization.

Infective endocarditis (IE)

An infection caused by pathogens that enter the bloodstream and settle in the heart lining, one or more heart valves, or blood vessels.

Amoxicillin

The oral regimen of choice for non-penicillin allergic patients; the current recommended adult dose is $2\,g$ taken $30$ to $60$ minutes before a procedure.

Cyanotic CHD

Unrepaired congenital heart disease, including palliative shunts and conduits, identified as a cardiac condition for which $AP$ is reasonable.

NICE (National Institute for Health and Clinical Excellence)

An organization in the UK that issued a total restriction on $AP$ in $2008$, stating it was not recommended for people undergoing dental procedures.

Viridans group streptococci

Oral flora that may become relatively resistant to beta-lactams in patients already receiving oral penicillin for other purposes.

Cephalosporins

A class of antibiotics that should not be used for $AP$ in individuals with a history of anaphylaxis, angioedema, or urticaria with penicillins or ampicillin.

2-hour rule

The protocol stating that if the antibiotic dosage is inadvertently omitted before a procedure, it may be administered for up to $2$ hours after the procedure.

10-day delay

The suggested waiting period before performing dental treatment on patients already taking penicillin to allow re-establishment of usual oral flora.

Prosthetic Joint Implant Infection (PJI)

A potential complication for patients with prosthetic joints receiving dental care, though $2015$ guidelines generally do not recommend routine $AP$ for its prevention.

Limited Recommendation

A grade of recommendation where the quality of supporting evidence is unconvincing, or well-conducted studies show little clear advantage to one approach versus another.

Inconclusive Recommendation

A grade of recommendation where there is a lack of compelling evidence resulting in an unclear balance between benefits and potential harm.

Consensus Recommendation

A grade of recommendation supported by expert opinion even when no available empirical evidence meets inclusion criteria.

Clostridium difficile

An opportunistic infection cited as a potential harm of unnecessary antibiotic use and a rationale for limiting $AP$ to prevent $PJI$.

Heart transplant recipients

A patient group at the highest risk of $IE$ during the first $6$ months after the procedure due to endothelial disruption and immunosuppressive therapy.
