Chest infections — over 5 years

Cough doesn’t always mean chest infection. Consider other causes — especially if shortness of breath is main problem

Red Flags — Urgent Medical Consult
  • Frail
  • Elderly
  • Chronic lung disease
  • Diabetes, kidney problems, liver disease
  • Heart failure
  • Cancer
  • Volatile substance misuse, alcohol misuse
  • Confused, altered mental state
  • Sepsis — signs and symptoms can include
    • High or low temperature
    • Fast breathing
    • Fast pulse
    • Low BP or dizziness
    • Confusion and/or agitation

Tropical Northern Australia

Consider melioidosis if moderate/severe pneumonia and risk factors of

  • Diabetes
  • Alcohol misuse
  • Kava use
  • Chronic kidney disease
  • Chronic lung disease
  • Medicines that suppress immune system
  • Cancer

Ask

  • Symptoms — cough, fever, wheeze, chest pain, shortness of breath, sputum
  • How long have they had symptoms 
  • History of previous chest infections — consider chronic lung disease
  • Other medical conditions — see red flags
  • Smoking — how many, how long, tried to stop, want to stop

Check

  • Calculate age-appropriate REWS
    • 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
  • ECG 
  • Head-to-toe exam — listen to chest

Do

  • Check for respiratory management plan
  • Pneumonia, bronchitis, exacerbations of bronchiectasis and COPD can look the same but treatment is different
  • If history of positive Pseudomonas and severe infection or septic shock — will need treatment with antipseudomonal antibiotics
  • Medical consult

Severe pneumonia

Fever, usually cough AND any of

  • Looks very unwell
  • Short of breath
  • Pulse more than 100 beats/min
  • Fast breathing — RR 26/min or more
  • O2 sats less than 94% on room air — when settled with good oximeter trace
    • If known chronic lung disease — check what O2 sats are when well
  • Temp less than 35°C OR more than 39°C
  • Low systolic BP for age or compared to previous measurement
  • Confused, altered mental state
  • Pain with breathing or percussion (tapping on chest)
  • Rib recession
  • Red flags

Do

  • Medical consult — consider sepsis
  • Give oxygen to target O2 sats 94–98% OR if moderate/severe COPD 88–92%
  • IV cannula
  • Blood cultures, urine for MC&S, sputum for MC&S
    • Ideally before giving antibiotics, but do not delay treatment — send in with person
  • Give ceftriaxone IV/IM — doses — single dose
    • AND azithromycin oral — doses — single dose
    • AND gentamicin IV/IM — doses— single dose
    • If allergy — medical consult
  • If low systolic BP for age — give normal saline bolus as directed by doctor

Mild or moderate pneumonia

  • Fever, usually cough AND
    • Looks unwell
    • Fast breathing — RR 21–25/min
    • O2 sats 94% or more on room air — when settled with good oximeter trace
    • If known chronic lung disease — check what O2 sats are when well
    • No other features of severe pneumonia

Table 7.20  Antibiotics for mild and moderate pneumonia

Mild Moderate
  • Give amoxicillin oral — adult 1.5g, child 35mg/kg/dose up to 1.5g — doses — twice a day (bd) for 5 days
