o The clinician may require different antibiotic choice, dosage, and/or treatment time if the<br />

infant has bacterial meningitis. Perform a follow-up lumbar puncture within 24-36 hours<br />

after antibiotic therapy has been initiated to determine if the CSF is sterile. If organisms<br />

are still present, modification <strong>of</strong> drug type or dosage is required to adequately treat the<br />

meningitis. Continue antibiotic treatment for 2 weeks after sterilization <strong>of</strong> the CSF or for a<br />

minimum <strong>of</strong> 2 weeks for gram-positive meningitis and 3 weeks for gram-negative<br />

meningitis, whichever period is longest. Chloramphenicol or trimethoprimsulfamethoxazole<br />

has been shown to be effective in the treatment <strong>of</strong> highly resistant<br />

bacterial meningitis.<br />

• Granulocyte transfusion has been shown to be suitable for infants with significant depletion <strong>of</strong><br />

the storage neutrophil pool; however, the documentation <strong>of</strong> storage pool depletion requires a<br />

bone marrow aspiration, and the granulocyte transfusion must be administered quickly to be<br />

beneficial. The number <strong>of</strong> potential adverse effects, such as graft versus host reaction,<br />

transmission <strong>of</strong> CMV or hepatitis B, and pulmonary leukocyte sequestration, is considerable.<br />

Therefore, this therapy remains an experimental treatment.<br />

• IVIG has been considered for neonatal sepsis to provide type-specific antibodies to improve<br />

opsonization and phagocytosis <strong>of</strong> bacterial organisms and to improve complement activation<br />

and chemotaxis <strong>of</strong> neonatal neutrophils; however, difficulties with IVIG therapy for neonatal<br />

sepsis exist. The effect has been transient, and adverse effects associated with the infusion<br />

<strong>of</strong> any blood product can occur. Dose-related problems with this therapy decrease its<br />

usefulness in neonatal populations.<br />

• Recombinant human cytokine administration to stimulate granulocyte progenitor cells has<br />

been studied as an adjunct to antibiotic therapy. These therapies have shown promise in<br />

animal models, especially for GBS sepsis, but require pretreatment or immediate treatment<br />

to demonstrate efficacy. The use <strong>of</strong> granulocyte-macrophage colony-stimulating factor (GM-<br />

CSF) and granulocyte colony-stimulating factor (G-CSF) has been studied in clinical trials,<br />

but their use in clinical neonatology remains experimental.<br />

• The infant with sepsis may require treatment aimed at the overwhelming systemic effects <strong>of</strong><br />

the disease. Cardiopulmonary support and intravenous nutrition may be required during the<br />

acute phase <strong>of</strong> the illness until the infant's condition stabilizes. Monitoring <strong>of</strong> blood pressure,<br />

vital signs, hematocrit, and platelets is vital.<br />

Surgical Care: If hydrocephalus associated with neonatal meningitis occurs, and progressive<br />

accumulation <strong>of</strong> CSF is present, placing a ventriculoperitoneal (VP) shunt may be necessary to drain<br />

<strong>of</strong>f the excess fluid. The immediate complications <strong>of</strong> shunt placement are overdrainage, equipment<br />

failure, disconnection, migration <strong>of</strong> catheter, or shunt infection. Abdominal obstruction, omental cysts,<br />

and perforation <strong>of</strong> the bladder, gall bladder, or bowel occur infrequently. The VP shunt may cause<br />

long-term neurologic complications, including slit-ventricle syndrome, seizures, neuroophthalmological<br />

problems, and craniosynostosis; however, the outcome for children with VP shunt<br />

placement is generally good with careful follow-up.<br />

Consultations:<br />

• Infectious disease consultation is useful, especially if the infant is not responding to treatment<br />

and/or if an unusual clinical sign is present, such as an unknown rash.<br />

• If neonatal meningitis is identified, consultation with a pediatric neurologist may be necessary<br />

for assistance with the initial short-term care or for subsequent outpatient follow-up <strong>of</strong><br />

neurologic sequelae.<br />

• Consultation with a pediatric pharmacologist may be helpful for advice on dosage and/or<br />

antibiotic changes that are necessary because <strong>of</strong> inadequate or toxic levels obtained with<br />

therapeutic monitoring.<br />

Diet: The neonate may need to be given nothing by mouth (NPO) during the first days <strong>of</strong> treatment<br />

because <strong>of</strong> gastrointestinal symptoms or poor feeding. Consider parenteral nutrition to ensure that<br />

the patient's intake <strong>of</strong> calories, protein, minerals, and electrolytes is adequate during this period.<br />

Feeding may be restarted via a nasogastric tube for the infant with serious compromise. Encourage<br />

that breast milk be given because <strong>of</strong> the immunologic protection it provides.
