  • MUHIMBILI UNIVERSITY OFHEALTH AND ALLIEDSCIENCESNURSING SCHOOL OF DEPARTMENT OF CLINICAL NURSING PEDIATRIC NURSING TOPIC:MANAGEMENT OF CHILD WITH MENINGITIS PRESENTER:SONGOMA JOHN
  • INTRODUCTIONMeningitis is an inflammation of the meninges , the protective membranes that surround the brain and spinal cord.Common causes of meningitis may include: Bacteria, Virus, Fungi and Parasites. Most episodes of meningitis result from hematogenous seeding of infection from other sites to the meninges.
  • 1. Bacterial causesVaries with age:1. Newborn to 3 months of age: E. coli and other coliforms, group B Streptococci, Listeria monocytogenes, Strep pneumoniae, H. influenza type b, Neisseria meningitidis2. Age 3 months to adolescence: N. meningitidis, S pneumoniae, H influenza type b (in young children) Mycobacterium tuberculosis is most common in young children, but can affect children of any age.
  • . Fungal Causes Common in immunocompromised patients. May include:Histoplasma , Coccidioides ,Paracoccidiodes ,Candida , Aspergilus Cryptococcus neoformans Viral Causes (aseptic meningitis) include:- Mumps Enterovirus (coxackie, polio) Adenovirus and Herpes simplex
  • Classification of meningitis1. Based on duration, meningitis is classified as:  Acute: symptoms present within a period of 0 – 24 hrs  Sub acute: symptoms lasting from 1-7 days.  Chronic: symptoms lasting over 7 days2. Based on aetiology:  Bacterial meningitis  Viral (aseptic) meningitis  Fungal meningitis
  • Clinical Presentation: Symptomsand signs1. Young infants < 3 months: The signs and symptoms are non specific and may include:  Fever or hypothermia  Bulging fontanelle or acute increase in head circumference  Convulsions / seizures  High-pitched cry, irritability  Lethargy, altered mental state  Apnoea  Poor feeding, vomiting.
  • 2. Children > 3 months to adolescents:  Fever is present in about ~ 50% of patients.  Headache, photophobia, stiff neck, irritability or lethargy, vomiting and altered level of consciousness.  Kerning’s sign in older children (inability to completely extend the leg).
  •  Brudzinski’s sign in older children (flexion at the knee in response to forward flexion of the neck). Convulsions in 20 – 30% of cases. Focal neurological deficits due to vasculitis or thrombosis of blood vessels. Papilledema (Swelling of the optic disc (where the optic nerve enters the eyeball); usually associated with an increase in intraocular pressure) is uncommon unless in advanced cases. This suggests increased intracranial pressure.
  • Laboratory Investigations1. CSF  Lumbar puncture or a shunt tap is performed as soon as the diagnosis of meningitis is suspected.  CSF should be examined for:  Microbiology and  Biochemistry
  • Laboratory Investigations cont.2. C-Reactive protein (CRP).3. Blood culture and other cultures (urine, abscess, and middle ear).4. Full Blood Picture (CBC) and ESR.5. Serum electrolytes, BUN, Creatinine.
  • Investigations cont6.Other examinations  Electroencephalogram (EEG) if seizures are prominent.  Head imaging (CT). Indications for CT are:  Focal neurological examination findings,  Seizures,  Increasing head circumference,  Lack of improvement despite appropriate treatment and  Suspected brain abscess.  CTshould only be done when the patient is stable.
  • Medical Treatment of Meningitispediatric1. Triage and ensure the ABCDs.2. IV line for IV medication and rehydration3. Drug therapy.
  • Treatment of Bacterial meningitis 1  Give antibiotic treatment as soon as possible: 1. Infants < 3 month old:  Ampicillin 200 mg/kg/day IV div q6hr, PLUS  Cefotaxime 200 mg/kg/day IV div q6hr for 10 to 14 days
  • Treatment of bacterial meningitis 2 2. Age 3 months to < 18 years; choose on of the following regimens: 1) Chloramphenicol 25 mg/kg IV (or IM) 6 hourly, plus Ampicillin 50 mg/kg IV (or IM) 6 hourly 2) Chloramphenicol 25 mg/kg IV (or IM) 6 hourly, plus Benzyl penicillin 6o mg/kg (100,000 IU /kg) IV or IM 6 hourly.
  • Treatment of bacterial meningitis 2 2. Age 3 months to < 18 years; choose on of the following regimens: 1) Chloramphenicol 25 mg/kg IV (or IM) 6 hourly, plus Ampicillin 50 mg/kg IV (or IM) 6 hourly 2) Chloramphenicol 25 mg/kg IV (or IM) 6 hourly, plus Benzyl penicillin 6o mg/kg (100,000 IU /kg) IV or IM 6 hourly.
  • Treatment of bacterial meningitis 3 Alternative treatment:  If Haemophilus influenza or Pneumococcus is common; 1) Ceftriaxone 50 mg/kg IV or IM 12 hourly or 100 mg/kg IV od for up to 10 – 14 days, or 2) Cefotaxime 50 mg/kg every 6 hrs for 3 weeks.
  • Supportive Treatment  Give paracetamol 15 mg/kg 6 – 8 hrly for fever (>38.50 C)  IV fluids: isotonic fluids at maintenance rate (250 ml/24hrs).  Feeding according to age requirement (75 – 100 kcal/kg/day).  Give anticonvulsant if convulsing  Correct hypoglycemia if present  NGT for feeding  Physiotherapy
  • Nursing management Monitor vital signs 2-4 hrly (Temperature, Pulse rate, Oxygen saturation, BP, and Respiratory Rate) Monitor Input/output Give treatment as prescribed. Maintain a clear airway• Turn the patient every 2 hours.• Do not allow the child to lie in a wet bed.• Pay attention to pressure points Monitor IV fluids very carefully and examine frequently for signs of fluid overload
  •  Nurses should monitor the child’s state of consciousness, respiratory rate and pupil size every 3 hours during the first 24 hours (thereafter, every 6 hours). On discharge, assess all children for neurological problems, especially hearing loss. Measure and record the head circumference of infants. If there is neurological damage, refer the child for physiotherapy, if possible, and give simple suggestions to the mother for passive exercises
  • Nursing management atemergency Step one Triage according to clinical indicators. Step two Prioritise care. The nurse’s role is to prioritise Airway, Breathing and Circulation, accompanied by a rapid assessment of conscious level using the AVPU# scale.
  •  Step threeFollow with specific nursing assessments. These should include the following:■ Assess for decreased cerebral tissue perfusion related to increased ICP:– neurological observations, including blood pressure should be performed at intervals determined by the child’s clinical state– assess for increased ICP– monitor fluid and electrolyte status.■ Assess for ineffective breathing pattern related to increased ICP:
  • Assess for potential for injury related to seizures:– document characteristics of seizure activity-duration, characteristics of motor behaviour and post-ictal phase– assess the patient’s environment for potential hazards.■ Assess for alteration in fluid and electrolytes related to SIADH, DI, diuretics, fluid restrictions:– monitor haemodynamic parameters– monitor urine output– monitor SG, urine electrolytes and osmolality.■ Assess for alterations in comfort related to meningeal irritation, headache, photophobia, fever– monitor temperature and assess effectiveness of comfort measures.
