meningitis 

meningitis is the inflammation covering the brain(meninges)

causes.

• bacteria  example: Haemophilus influenzae type b (Hib, Neisseria meningitidis, Listeria monocytogenes, Group B Streptococcus, Streptococcus pneumoniae.
• viruses examples:Enteroviruses ,Herpes viruses ,Mumps virus,HIV,Varicella-Zoster Virus.
• Fungal Meningitis.Candida species,Cryptococcus neoforman
• protozoa:plasmodium
• medications.
• Autoimmune 
• Malignant (carcinomatous meningitis)
• Chemical.

predisposing factors

• hiv infection
• unvaccinated child 
• children
• newborn baby
• premature baby
• preterm baby

Pathophysiology

The infection usually begins when microorganisms enter the body through: The nose or throat, The bloodstream, Direct entry due to head injury, surgery, or skull fracture.

After entering the body, the organism multiplies and spreads into the blood.

From the blood, it travels toward the central nervous system (CNS).

The microorganisms then crosses the blood–brain barrier(BBB)it is a protective layer that normally prevents harmful substances from reaching the brain.
Once this barrier is breached, the organisms enter the cerebrospinal fluid (CSF).then

The organisms multiply rapidly because the CSF has few immune defences, so in the process the present of micro organism triggers the body’s immune response.

The immune system releases inflammatory chemicals (cytokines) to fight the infection.
This causes: Inflammation of the meninges, Increased white blood cells in the CSF, Increased capillary permeability

 Inflammation then  leads to: Swelling of brain tissue (cerebral oedema),Increased production and reduced absorption of CSF
This raises intracranial pressure, which can reduce blood flow to the brain.

Reduced blood flow and pressure on brain tissue lead to symptoms such as:Severe,headache,Fever,Neck stiffness,Vomiting,Altered consciousness, Seizures (in severe cases)

Signs and symptoms

the patient will present with the following clinical future.

Children

• High pitch crying
• Bulging fontanel
• Restlessness
• Stiff neck
• Convulsions
• Sever headache
• High grade fever
• Photophobia
• Unconsciousness
• Nausea and Vomiting

Adult

• Stiff neck
• Convulsions
• Severe headache
• High grade fever
• Photophobia
• Unconsciousness
• Nausea and Vomiting

Differential diagnosis

• Brain abscess
• Brain tumour
• Drug reaction.

Investigations

History taking

Take the pass medical history, surgical history, any drug taken

Physical examination

1. Do the general physical examination from head to toe.
2. Do the Glasco coma scale rating the level of consciousness
3. Do the kernig sign and Brudzinski sign it is the confirmatory test for meningitis.

Laboratory investigations.

• Lumbar puncher looking at the colour of the csf, the speed it is flowing.
• Csf analysis looking for weight blood cell count,sugar,protein, pus cell.
• Csf culture and sensitivity
• Csf gram stain also gene expert
• Blood for cbc and serological examination

Imaging investigation

• Mri
• Ct scan

Management

Management depend on the cause.

For bacteria

Give antibiotics.Ceftriaxone hight dose 2g you can divided it to 2 devided dosage ie ceftrazon 1g twice a day for 7days for adult.Ampicillin 2g 6 hourly can also be added.

For children give 100mg/kg body weight.for example if the child’s weight is 10kilogram.then multiply the weight by 100mg that is 1000mg (1g) and devide it in to 2 dosage(bd)

you can use chramphenical if cefriaxon not available.

Other antibiotics

·        Benzylpenicillin

·        Antituberclosis medications

·        Clxacillin

·        Gentamicine

·        Ceftaxin(neonate)

If virus give antiverial drug like acyclovir iv or oral depending on the condition

If protozoa give antiprotozoal eg malaria give antimalarial drug.

If fungi administer antifungal medications

Other management you manage the symptoms.

Convulsion give anticonvulsant like phenobarbitone, diazepam, phenytoin.

Monitor the laboratory result

Fever manages fever with antipyretics

Vomiting administer antiemetic

Nursing management(specific nursing management /nursing care) for a patient admitted with meningitis.

1.      1        Monitor level of consciousness using Glasco coms scale
2.     Take and monitor vital signs that to say temperature, pulse, respiration and blood pressure

Pathophysiology (Simplified)

Microorganisms enter the body through the nose, throat, bloodstream, or direct injury.
They multiply and spread in the blood, then cross the blood–brain barrier into the cerebrospinal fluid (CSF).
Because CSF has limited immune defense, organisms multiply rapidly and trigger an inflammatory response.
Inflammation leads to cerebral edema, increased CSF volume, and raised intracranial pressure, reducing blood flow to the brain.
This results in symptoms such as fever, severe headache, neck stiffness, vomiting, altered consciousness, and seizures.

9. What conditions can be mistaken for meningitis?

Conditions such as brain abscess, brain tumor, and drug reactions can mimic meningitis.

10. How is meningitis investigated?

Investigations include history taking, physical examination, Glasgow Coma Scale assessment, Kernig’s and Brudzinski’s signs, lumbar puncture, CSF analysis, blood tests, and imaging studies like CT scan and MRI.

11. Why is lumbar puncture done in meningitis?

Lumbar puncture helps examine the cerebrospinal fluid for color, pressure, white blood cells, sugar, protein, and presence of microorganisms.

12. How is meningitis managed?

Management depends on the cause and includes antibiotics for bacterial meningitis, antivirals for viral causes, antifungal drugs for fungal infections, and antiprotozoal drugs when indicated.

13. What supportive treatment is given to meningitis patients?

14. What are the key nursing responsibilities in meningitis care?

Nurses monitor level of consciousness, vital signs, fluid balance, administer medications, control fever, maintain a quiet environment, ensure patient safety, provide nutrition, maintain hygiene, and educate patients and caregivers.

15. What nursing diagnoses are commonly associated with meningitis?

Common diagnoses include hyperthermia, acute pain, impaired cerebral tissue perfusion, ineffective airway clearance, impaired mobility, disturbed sensory perception, and risk for seizures and aspiration.

16. Why is patient positioning important in meningitis?

Elevating the head of the bed helps reduce intracranial pressure and improves cerebral blood flow.
