Meningitis

Consider meningitis in

 

  • Meningitis may present differently in babies, elderly and anyone recently on antibiotics
  • Potential cause for fever (eg infection, doesn't rule out meningitis)
  • Normal coma scale score doesn't rule out meningitis
  • If suspected meningitis urgent medical consult — treatment needs to be started quickly

Do not

  • Do not leave person alone
  • Do not allow person to go home until meningitis has been excluded and an alternative cause of symptoms has been found

    • Adult — AVPU, RR, O2 sats, pulse, BP, Temp
    • Child (less than 13 years) — AVPU, respiratory distress, RR, O2 sats, pulse, central capillary refill time, Temp
  • Weight, BGL
  • Coma scale
  • Head-to-toe exam 

Do

  • Urgent medical consult
  • Put in IV cannula
  • Collect before giving antibiotics if possible, but do not delay treatment if you can’t get samples

Public health issues

  • If meningitis confirmed
    • Notify local PHU
    • Make list of people in household the person has been in contact with in past week. Record weights of all children under 30kg
  • If meningococcal or HiB meningitis confirmed
    • Send list of contacts and weights to PHU
    • PHU will tell you if you need to treat contacts, give you advice about immunisation
