WEEK 7: Nervous System and Pain Control Flashcards
Meningitis
Meningitis is characterized by the infection and inflammation of the brain and spinal cord, leading to purulent exudate and increased intracranial pressure (ICP), with potential cranial nerve involvement
Explain the Etiology of Meningitis
-Bacterial Meningitis is caused by bacteria such as Neisseria meningitidis, Streptococcus pneumoniae, Group B streptococcus, and Haemophilus influenzae type B.
-Viral Meningitis: Known as aseptic meningitis, caused by viruses like Herpes simplex, mumps, Epstein-Barr virus, and cytomegalovirus (CMV)
(MENINGITIS) Signs and Symptoms
Common symptoms include severe headache, fever, photophobia, nuchal rigidity, and a petechial rash. Positive Kernig and Brudzinski signs indicate meningeal irritation
(MENINGITIS) Diagnostic Tests
-Lumbar Puncture (LP): Essential for diagnosis.
Viral Meningitis: Clear CSF, normal glucose, near-normal protein, elevated WBC.
-Bacterial Meningitis: Cloudy CSF, elevated WBC
(MENINGITIS) Complications
Seizures may occur in the post-acute phase, and cranial nerve damage can lead to blindness or deafness. Meningococcal meningitis can progress to meningococcemia, causing rapid death due to septicemia
(MENINGITIS) Therapeutic Interventions
Treatment includes antibiotics, antipyretics, analgesics, corticosteroids, and droplet isolation for bacterial meningitis
