- Other antibiotic sensitivities are available by special request through the microbiology lab.
- Pseudomonas, Enterobacter, Serratia and Acinetobacter have inducible betalactamases and may develop resistance while on monotherapy with beta-lactam antibiotics.
- Pneumococcus is developing significant resistance to penicillin, it is no longer the drug of empiric choice for serious infections like sepsis and meningitis.
- When starting empiric therapy for meningitis (age 1month-adult) vancomycin and dexamethasone are now recommended. Dexamethasone should be administered before the first antibiotic dose.
- When obtaining deep tissue, abscess or bone for culture be sure to send the specimen to the lab in a non-formalinized, sterile container. Pieces of tissue and bone are always better microbiologic specimens than swabs.
- Rifampin should never be used as monotherapy. Always use rifampin in combination with other anti-infective agents.
- Suspected bacterial meningitis patients should receive antibiotic within 30 minutes of reaching the medical care system.
- Patients with resistant organisms (i.e. MRSA, VRE) require special isolation. Please call Infection Control (x2892) and refer to the infection control manual.
- MRSA and methicillin resistant coagulase negative staphylocci should be considered resistant to all currently available B-lactam antibiotics.
- Combination therapy of penicillin, ampicillin or vancomycin, plus an aminoglycoside, is usually indicated for serious enterococcal infections, such as endocarditis.
- For surgical prophylaxis, antibiotics should be administered within one hour of incision.
