Paediatric Septic Shock

The key differences are that infants and younger children have different targets needed than adults, but that they can also recover in situations where adults wouldn't. 1

Defns

In children with infection fever, tachycardia, and vasodilatation are common. When combined with change in mental status shock should be considered. 1

Normal HR + Sys BP + Perfusion Pressure Ranges by Age: 1

Age HR Sys BP Perfusion Pressure
<1 110 - 160 70-90 60
2-5 95-140 80-100 65
5-12 80-120 90-110 65
12+ 60-100 100-120 65

Normal RR Ranges by Age: 1

Age RR
<1 30-40
1-2 26-34
2-5 24-30
5-12 20-24
12+ 12-20

Predisposition/Age

Neonatal Sepsis incidence is 4.3/1000 1

Neonatal Sepsis Mortality is 20% 1

Older Children Sepsis Mortality is around 10% 1

Children with predisposing factors (chemo, tubes, lines, ICU stays) are more likely to get nosocomial infections 1

Organisms

Less Than 3 Months

  • Group B Strep
  • Enterococcus
  • Listeria
  • Pseudomonas
  • E. coli 1

Older Than 3 Months

  • Neisseria meningitidis
  • Strep pneumo
  • Haemophilus influenzae 1

Nosocomial

  • Pseudomonas
  • Fungal
  • Translocated Gut Bacteria
  • Coagulase Negative Staph 1

Assessment

Categorise patients into:

  • Stable
  • Respiratory Failure (compensated or decompensated)
  • Cardiac Failure (compensated or decompensated)
  • Cardiorespiratory Failure 1

Differentiate a collapse between ones due to sepsis and ones due to duct dependent lesion in neonates - you need an echo for this. In that situation starting prostaglandin is low risk. 1

Purpuric Rash

  • Neisseria meningitidis 1

But also the following bugs can also cause it:

  • Haemophilus influenzae
  • Streptococcus pneumonia 1

Management

  • Oxygen
  • Vascular Access - Consider IO Access
  • IV Fluids - 20ml/kg aliquots
  • Vasopressors - After volume resuscitation (40-60ml/kg fluid) 1

Target variables:

Use the perfusion pressure: MAP-CVP = PP 1

Use the central venous oxygen saturation 1

Target inotropes to target perfusion pressure, age, and ScvO2 >70% 1

Dopamine usually first line agent in septic shock in paeds. 1

Also can consider a type III phosphodiesterase inhibitor for the refractory shocked patients 1

If catecholamine resistant start hydrocortisone (50mg/m2 - Stress Dose Hydrocortisone) 1

(Also In Adrenal Insufficiency give Hydrocortisone 1-2mg/kg 6hrly) 1

Extracorporeal Life Support?

In neonatal sepsis with refractory shock - 80% survival with ECLS 1

In paediatric septic refractory shock - 37-50% survival 1
