Bell's Palsy
Eye Protection
- Cornea eye protection (Level X)[1]
- Artificial tears qhr while patient is awake
- Ophthalmic ointment at night
- Eye should be taped shut at night
- Protective glasses or goggles
Steroids
Should be started within 72hrs of symptom onset[2]
- Prednisone 60-80mg qday x1wk[3] (Level B Evidence)[4]
Antivirals
Most likely no added benefit when combined with steroids.[5] However also little harm associated with antivirals especially in patients with normal renal function[4]
- Valacyclovir 1000mg TID x1 week[3] OR
- Acyclovir 400mg 5x per day x1 week
Antibiotics
- Consider empiric doxycycline if high index of suspicion for Lyme based on clinical presentation or lab data
Brain abscess
Otogenic source
- Cefotaxime 2gm IV q6hr + metronidazole 500mg IV q6hr
Sinogenic or odontogenic source
- Cefotaxime 2gm IV q6hr + metronidazole 500mg IV q6hr
Penetrating trauma or neurosurgical procedures
- Vancomycin 15mg/kg IV q12hr + ceftazidime 2gm IV q8hr
Hematogenous source
- Cefotaxime 2gm IV q6hr + metronidazole 500mg IV q6hr
No obvious source
- Cefotaxime 2gm IV q6hr + metronidazole 500mg IV q6hr
Encephalitis
Often it is unclear which type of encephalitis is present and starting Acyclovir empirically is appropriate. In addition to the pathogens below, possible causes can include West Nile Virus, EBV, HIV, toxoplasmosis, or rabies.
HSV encephalitis
- Acyclovir 10mg/kg (10-15mg/kg for pediatrics) every 8hrs
HZV encephalitis
- Acyclovir 10mg/kg every 8hr
CMV encephalitis
- Ganciclovir 5mg/kg IV every 12hr OR
- Foscarnet 90mg/kg IV every 12 hrs
Tick Associated (Borrelia burgdorferi, Ehrlichiosis or Rickettsia)
- Doxycycline 200 mg IV once followed by 100 mg IV twice daily
Epidural Abscess
- Target Staph, Strep, and Gram-negative bacilli[6]
- Vancomycin 15-20mg/kg BID + metronidazole 500mg (7.5mg/kg) q6 hrs + (Cefotaxime or Ceftriaxone or Ceftazidime)
- Ceftazidime is preferred if pseudomonas is considered likely
- Can substitute Nafcillin or Oxacillin for Vancomycin if not MRSA
Treat for 6-8 weeks
Meningitis
Neonates (up to 1 month of age)[7]
MRSA is uncommon in the neonate
- Ampicillin 75mg/kg IV q6hrs PLUS
- Cefotaxime 50mg/kg IV q6hrs OR Gentamicin 2.5mg/kg IV q8hrs
- Per AAP, ceftazidime 50mg/kg IV (q12hr for babies < 8 days of age, q8hr for >7 days old) is a reasonable alternative to cefotaxime, offering virtually the same coverage for enteric bacilli and is FDA approved for all age groups[8]
- If suspecting S. pneumoniae or MRSA, add Vancomycin
- Consider acyclovir for HSV
> 1 month old[9]
- Ceftriaxone 2gm (50mg/kg) IV BID daily PLUS
- Vancomycin 15-20 mg/kg IV BID daily
- Vancomycin is for resistant Pneumococcus
Adult < 50 yr[10]
- Ceftriaxone 2gm (50mg/kg) IV BID daily PLUS
- Vancomycin 15-20 mg/kg IV BID daily
- Vancomycin is for resistant Pneumococcus
Adult > 50 yr and Immunocompromised[11]
- Ceftriaxone 2gm (50mg/kg) IV BID daily PLUS
- Vancomycin 15-20 mg/kg IV BID daily PLUS
- Ampicillin 2gm IV q4h (hourly if listeria suspected)[12]
Post Procedural (or penetrating trauma)[13]
- Vancomycin 15-20mg/kg IV BID daily PLUS
- Cefepime 2g (50mg/kg) IV q8 hours daily OR Ceftazidime 2g (50mg/kg) IV q8 hours daily OR Meropenem 2gm (40mg/kg) IV q8 hours daily
Cryptococcosis Meningitis
Options
- Amphotericin B 1mg/kg IV once daily AND Flucytosine 25mg/kg PO q6hrs daily
- Amphotericin B 5mg/kg IV once daily AND Flucytosine 25mg/kg PO q6hrs daily
Meningitis with severe PCN allergy
- Chloramphenicol 1g IV q6h + Vancomycin 15mg/kg q8-12hr
Meningitis with VP shunt
- Coverage for skin contaminants (S. epidermis, S. aureus)
- Vancomycin plus ceftriaxone plus shunt removal
Neisseria meningitidis Prophylaxis
- Ceftriaxone 250mg IM once (if less than 15yr then 125mg IM)
- Ciprofloxacin 500mg PO once
- Rifampin 600 mg PO BID x 2 days
- if < 1 month old then 5mg/kg PO BID x 2 days
- if ≥ 1 month old then 10mg/kg (max at 600mg) PO BID x 2 days
Tetanus
- 500 mg IV every 6 hours
(<1200g)
- 7.5 mg/kg PO/IV q48h
- First Dose: 7.5 mg/kg PO/IV x 1
(>1200g AND <1 Month Old)
- <7 days old
- 7.5-15 mg/kg/day PO/IV q12-24h
- First Dose: 7.5-15 mg/kg PO/IV x 1
- >7 days old
- 15-30 mg/kg/day PO/IV q12h
- First Dose: 7.5-15 mg/kg PO/IV x 1
(>1 Month Old)
- 30 mg/kg/day PO/IV q6h
- First Dose: 7.5 mg/kg PO/IV x 1
- Max: 4 g/day
