Antibiotics
Class Summary
Mortality in meningococcal infections may be reduced with early antibiotic therapy; however, antibiotics may be less effective in patients with shock or poor tissue perfusion. Regarding community management, because mortality may be reduced with early antibiotic therapy, patients with a meningococcal rash should receive parenteral benzyl penicillin by means of an intravenous or intramuscular route as soon as the diagnosis is suspected. Intramuscular antibiotic injections may be less effective in a patient with shock and poor tissue perfusion. Give cefotaxime, ceftriaxone, or chloramphenicol to patients who are allergic to penicillin.
Empirical antibiotic therapy ensures coverage of likely meningeal pathogens when no rash is present, when the etiology of meningitis is uncertain, and when immediate microbiological diagnosis is unavailable. This approach can be modified in favor of appropriate specific therapy when the organism is identified or when its sensitivities to antibiotics are known. Empirical antibiotic therapy for meningitis based on age is as follows:
- Neonates - Ampicillin and cefotaxime
- Infants aged 1-3 months - Ampicillin and cefotaxime with or without vancomycin
- In older infants, children, and adults - Cefotaxime or ceftriaxone with or without vancomycin
Penicillin G (Pfizerpen)
Preferred agent for initial community management of suspected meningococcal disease.
Chloramphenicol (Chloromycetin)
Can be used in patients with penicillin and cephalosporin allergy.
Ampicillin (Marcillin, Omnipen, Polycillin, Principen, Totacillin)
Used for empiric treatment in neonates aged 0-3 mo to cover possible listeriosis.
Cefotaxime (Claforan)
First-line antibiotic for empiric therapy of meningitis or sepsis while culture and susceptibility data are pending. Cefotaxime or ceftriaxone are the preferred agents for the treatment of confirmed meningococcal disease.
Ceftriaxone (Rocephin)
First-line antibiotic for empiric therapy of meningitis or sepsis while culture and susceptibility data are pending; cefotaxime or ceftriaxone are the preferred agents for the treatment of confirmed meningococcal disease.
Vancomycin (Lyphocin, Vancocin, Vancoled)
Used for empiric management of sepsis and meningitis with risk of resistant pneumococcal infection. Has no activity against gram-negative bacteria, including meningococci.
Ciprofloxacin (Cipro)
Used for chemoprophylaxis of N meningitides infection in adults.
Rifampin (Rifadin, Rimactane)
Used for chemoprophylaxis of N meningitides infection.
Vasopressors
Class Summary
After basic life support and administration of antibiotics, treating shock is the next priority.
Dopamine (Intropin)
Stimulates adrenergic and dopaminergic receptors; hemodynamic effect depends on dose; Lower doses predominantly stimulate dopaminergic receptors that in turn produce renal and mesenteric vasodilation. Cardiac stimulation and renal vasodilation produced by higher doses. May be given via peripheral cannula prior to obtaining central venous access.
Dobutamine (Dobutrex)
First-line drug in meningococcal sepsis without central venous access; produces vasodilation and increases inotropic state; higher doses may increase heart rate and exacerbate myocardial ischemia; may be given via peripheral cannula prior to central venous access.
Epinephrine (Adrenaline)
For persistent hypotension. Has alpha-agonist effects (eg, increased peripheral vascular resistance, reversed peripheral vasodilatation, systemic hypotension, and vascular permeability) and beta-agonist effects (eg, bronchodilatation, chronotropic cardiac activity, positive inotropic effects).
Osmotic diuretics
Class Summary
These agents are used to control ICP during elective intubation. These agents raise the osmolality of plasma and renal tubular fluid, which creates an osmotic inhibition of water transport in the proximal tubule. This subsequently decreases the gradient for passive sodium absorption in the ascending limb of the loop of Henle. The increased urinary flow is achieved by a nonelectrolyte solute diuresis. Increases glomerular filtration rate may also be observed.
Mannitol (Osmitrol)
May reduce subarachnoid-space pressure by creating osmotic gradient between CSF in the arachnoid space and plasma; not for long-term use.
Diuretics
Class Summary
These agents promote excretion of water and electrolytes by the kidneys.
Furosemide (Lasix)
Mechanism for lowering ICP involves lowering cerebral sodium uptake, affecting water transport into astroglial cells by inhibiting cellular membrane cation-chloride pump, and decreasing CSF production by inhibiting carbonic anhydrase; administered after mannitol.
Glucocorticoids
Class Summary
These agents elicit anti-inflammatory and immunosuppressive properties and cause profound and varied metabolic effects. They modify the body's immune response to diverse stimuli.
Dexamethasone (Decadron, AK-Dex, Baldex, Dexone)
May reduce sensorineural hearing loss in children and infants with H influenzae type B meningitis. Administer to all children with suspected bacterial meningitis (pathophysiology likely to be similar). Does not reduce CNS clearance of bacteria or cause treatment failure.
