Antibiotic Prophylaxis for Dental Procedures

Since 2007, antimicrobial prophylaxis for dental
procedures has been recommended to prevent
viridans group streptococcal infective endocarditis
only for patients at highest risk of an adverse
outcome. Limiting use to such patients does not
appear to have led to an increased incidence of
infective endocarditis or increased mortality due to
infective endocarditis.

The FDA has approved delafloxacin (Baxdela –
Melinta), an anionic fluoroquinolone antibiotic, for oral
and parenteral treatment of adults with acute bacterial
skin and skin structure infections (ABSSSIs), including
those caused by methicillin-resistant Staphylococcus
aureus (MRSA). It is the first fluoroquinolone to be
approved for treatment of MRSA.
Drugs for Common Bacterial Infections in Adults

Bacterial infections in adults are generally treated
empirically, with the antibiotic covering most, but not
all, of the potential causative pathogens. For some
infections, culture and sensitivity testing can guide
treatment, allowing for use of narrower-spectrum
antibiotics. The recommended dosages and durations
of antibiotic treatment for common respiratory, skin, and
urinary tract infections are listed in Tables 1-3. Infectious
disease experts now recommend shorter treatment
durations for many infections to reduce the development
of antimicrobial resistance and minimize adverse effects.

The FDA has approved oritavancin (Orbactiv – The
Medicines Company), a long-acting lipoglycopeptide
antibiotic given as a single intravenous (IV) dose, for
treatment of acute bacterial skin and skin structure
infections caused by susceptible gram-positive
bacteria in adults. It is the third lipoglycopeptide
antibiotic to be marketed in the US; telavancin (Vibativ)
and dalbavancin (Dalvance) were approved earlier.

The FDA has approved ceftaroline fosamil (Teflaro –
Forest), an intravenous (IV) cephalosporin, for treatment
of acute bacterial skin and skin structure infections,
including those caused by methicillin-resistant
Staphylococcus aureus (MRSA), and for treatment of
community-acquired bacterial pneumonia in adults. It
is the first beta-lactam antibiotic approved for treatment
of MRSA.
In Brief: Recommendation for Earlier Antibiotic Prophylaxis for Cesarean Delivery
The Medical Letter on Drugs and Therapeutics • October 4, 2010; (Issue 1348)

The American Congress of Obstetricians and Gynecologists (ACOG) has announced a new recommendation for antibiotic prophylaxis during cesarean delivery.1 Currently most women receive a single dose of prophylactic antibiotics after the umbilical cord has been clamped to prevent antibiotics from crossing over to the newborn. The new recommendation is for women giving birth by cesarean section to routinely receive antibiotics within one hour before the start of surgery. In the case of an emergency cesarean delivery, prophylaxis should be started as soon as possible.
Recent studies have found a lower incidence of endometritis and wound infection with preoperative antibiotic administration compared to administration post-clamping.2-4 Whether widespread adoption of this practice could increase neonatal morbidity by masking the source of sepsis or by increasing the prevalence of resistant organisms remains to be determined.
The prophylactic antibiotic for cesarean section is cefazolin 1-2 g IV. For patients allergic to penicillins and cephalosporins, clindamycin with gentamicin would be a reasonable alternative.

On page 100 of the article "Major Changes in Endocarditis Prophylaxis for Dental, GI and GU Procedures", under the section Highest-Risk Procedures, the word "rubber" should have been omitted. Placement of orthodontic rubber bands is not a highest-risk procedure that justifies prophylaxis; placement of orthodontic (metal) bands is. An orthodontic band is a metal ring that surrounds the tooth and is pressed into place causing movement in closely-spaced teeth and sometimes bleeding when the bands are placed close to the gumline.

The American Heart Association has issued its revised guidelines for prevention of infective endocarditis. Antimicrobial prophylaxis for dental procedures is now recommended only for patients at the highest risk of severe consequences from endocarditis who are undergoing the highest-risk procedures. Endocarditis prophylaxis is no longer recommended for gastrointestinal (GI) and genitourinary (GU) procedures. When these changes are implemented, the number of patients receiving antimicrobial prophylaxis to prevent endocarditis should decline sharply.

Many physicians believe that antimicrobial prophylaxis before procedures that may cause transient bacteremia can prevent endocarditis and prosthetic joint infection in patients at increased risk for these disorders. The effectiveness of this common practice has never been established by controlled trials in humans.

Antimicrobial prophylaxis can decrease the incidence of infection, particularly surgical site infection, after certain operations, but this benefit must be weighed against the risks of toxic and allergic reactions, emergence of resistant bacteria, adverse drug interactions, superinfection and cost. Medical Letter consultants generally recommend antimicrobial prophylaxis only for procedures with high infection rates, those involving implantation of prosthetic material, and those in which the consequences of infection are likely to be especially serious.

A penicillin is the drug of choice for treatment of many infections, but allergic reactions to these drugs occur frequently and, rarely, can be fatal. From 5% to 20% of patients have a history of a rash or some other reaction while taking a penicillin, but maculopapular rashes with ampicillin or amoxicillin, especially in children with infectious mononucleosis, are probably not allergic.
