The interpretation and application of clinical guidelines will remain the responsibility of the individual clinician. If in doubt contact a senior colleague or expert. Caution is advised when using guidelines after the review date.

2 Meningococcal Disease Meningococcal disease (MCD) is caused by systemic infection with Neisseria meningitides; type B is most common. It often results in a clinical picture of septicaemia and can occur with or without meningitis. Signs and symptoms of meningitis and meningococcal disease Signs/Symptoms Bacterial meningitis Meningococcal septicaemia Notes Common non-specific signs/ symptoms Fever Vomiting/nausea Lethargy Irritability Ill appearance Refusing food/fluid Headache Myalgia / arthralgia Respiratory distress Not always, especially neonates. Less common non-specific signs/symptoms Rigors Abdominal pain / distension / diarrhoea NK Upper resp tract signs or symptoms NK More specific signs/symptoms Non-blanching rash Difficult in darker skin tones. Stiff neck NK Altered mental state CRT > 2 seconds NK Unusual skin colour NK Hypotension NK Cool peripheries NK Leg pain NK Back rigidity NK Bulging fontanelle NK < 2 years Photophobia X Kernig s sign X Brudzinki s sign X Unconsciousness Moribund/toxic state Paresis X Focal neurological deficit X Seizures X X not present, present, NK not known within evidence, CRT capillary refill time.

3 Signs of shock: Tachycardia/ hypotension CRT > 2 seconds / unusual skin colour / cool peripheries Respiratory distress / hypoxia Leg pain Toxic/moribund state Altered mental state Poor urine output < 1ml/kg/hr Base deficit > -5 mmol/l Lactate >2 mmol/l Classical signs of meningitis may be difficult to determine in infants and children and young people tend to present with non-specific signs and symptoms. Meningococcal disease and meningitis often occur together. Be sure to record: HR, RR, temp, BP, perfusion, conscious level, oxygen saturations at least hourly in any child with suspected meningitis or meningococcal disease. Prepare to consult with PICU about all cases of suspected meningococcal disease and meningitis< 2years. Investigation and management of a child with suspected meningococcal septicaemia: Gain IV access send blood samples for FBC, CRP, U+E, glucose, calcium, magnesium, clotting, blood gas, lactate, Blood culture and meningococcal PCR. Give IV ceftriaxone 80 mg/kg. Continue at a once daily dose. Give for 7 days in both confirmed and unconfirmed/suspected cases. Chloramphenicol may be used in type 1 sensitivity to cephalosporins, 40 mg/kg bolus then 25mg/kg 8 hourly IV/PO. Fluids MCD is often associated with hypovolaemia. If signs of shock give 20 ml/kg of 0.9% saline over 5-10 mins immediately and reassess. If still in shock give another 20 ml/kg of 0.9% saline or 4.5% human albumin and reassess. If shock persists give another 20 ml/kg of 0.9% saline or 4.5 % albumin and call for PICU + anaesthetist to prepare for intubation. These children can need a lot of fluid to restore their circulating volume. Never use 5 or 10% dextrose. These children will need regular reassessment even if good improvement is seen. Reassessment should be based on the child s clinical condition but in a child who has shown good improvement it is still recommended they be reassessed after 30 minutes and then on an hourly basis until sure the child is in a stable condition. Do not give corticosteroids for meningococcal septicaemia.

4 Acute complications: ABC: ensure airway patent, airway manoeuvres + adjuncts, oxygen, anaesthetic review, intubation. Shock: see above signs and fluid management. Acidosis Hypoglycaemia: 5ml/kg 10% dextrose. Hypokalaemia / hypocalcaemia/ hypomagnesaemia. Raised ICP: ABC, oxygen, head raised 30 o, mannitol 0.25g/kg, intubate + ventilate (PaCO kPa). Deranged clotting. Seizures. Manage as per APLS. Later complications: Small vessel thrombosis / tissue loss involve wound team, pain team and plastics. Appropriate analgesia, may need opiates. Reactive arthritis or pericarditis can occur from day 3-7. Fever persisting beyond 7 days tissue damage (vasculitis), nosocomial infection, subdural effusion, suppurative foci, inadequately treated meningitis, parameningeal focus or drugs. Notification: All cases of confirmed or presumed N. Meningitidis should be urgently notified to public health. Contact via ambulance control Contact chemoprophylaxis (meningitis and meningococcal disease): Needs to be given within 24 hours. All household/day care contacts who have been exposed within 10 days of onset. Anyone who gave mouth to mouth resuscitation to index case. Infants < 1 month Rifampicin 20 mg PO 12 hourly for 2 days. Infants 1 month - 4 months Ciprofloxacin 125 mg as stat dose. Infants 5 months 1 year Ciprofloxacin 250 mg as stat dose. Children > 1 year Ciprofloxacin 500 mg as stat dose. Warn contacts on Rifampicin about orange-red discolouration of bodily fluids, can cause itching, skin rash and GI disturbance. Negates effect of contraceptive pill. Contraindicated in pregnancy / breastfeeding/ severe liver and renal disease.

5 Long term management and follow-up: All patients with meningitis and meningococcal septicaemia need paediatric follow-up to monitor the occurrence of the following complications: Hearing loss (associated with meningitis) All children require age appropriate test prior to discharge. Repeat test 6 weeks after discharge if fail first test. Out-patients appointment within 6 weeks to discuss results of the test. To arrange hearing test please contact ext at Denbigh house. Orthopaedic complications damage to bones and joints. Skin complications - scarring from necrosis. Psychosocial problems children can remember their ordeal. Neurodevelopmental problems. Renal failure. Be sure to inform the GP, health visitor and school nurse of the child s condition. Ensure that adequate discussion has taken place with the family about follow-up care, relevant complications and how to access relevant support ie through charities / counselling.

6 Algorithm for the early management of Meningococcal septicaemia RECOGNITION: may present with septicaemia with shock, meningitis with ICP, purpuric/petechial rash. If high clinical suspicion or confirmed case, notify public health and consider chemoprophylaxis of close contacts. Call SPR, paeds/ed consultant. Assess for shock and ICP. DO T PERFORM LUMBAR PUNCTURE ABC: oxygen 15 L/min Large IV/IO access: gluc, FBC, coag, U+E, Ca, Mg, gas, men PCR, blood culture Ceftriaxone 80 mg/kg IV/IO Use cefotaxime 50 mg/kg if calcium-containing fluids or age <3 months Go to meningitis algorithm DO T a DO LP. 20 ml/kg 0.9% saline bolus SHOCK? ICP? Signs of meningitis? Further 20 ml/kg 0.9% saline or 4.5% albumin if shock persists. Check Glu Observe response DO T DO LP, Check Glu Mannitol (0.25g/kg) Repeat review for signs of shock / ICP After 40 ml/kg still signs of shock? Repeated review for signs of shock Call anaesthetist/picu NG/ catheter Treat shock then cautious fluids Children can deteriorate quickly. Call anaesthetist + PICU Treat seizures 20 ml/kg 0.9% saline/4.5% albumin. May need repeat boluses. Prepare ET tube, NG tube, urinary catheter. Go to meningitis guideline and algorithm Consider inotropes- dopamine/ adrenaline. Consider metabolic disturbances. Reassess.
