Why are we worried about it? Still remains significant cause of morbidity and mortality 5 -30% of paediatric patients with sepsis will develop septic shock. Mortality rates in septic shock are 20 -30% (up to 50% in some countries).

Recognition Most people don’t recognise shock Resuscitation must be done in a proactive time-sensitive manner Every minute counts – “golden hour” Every hour without appropriate resuscitation and restoration of blood pressure increases mortality risk by 40%

Blood Pressure in Children This is main difference with adults. Blood pressure does not fall in septic shock until very late. CO= HR x SV HR in children much higher therefore BP falling is late. Pulse pressure is often useful Normal: Diastolic BP > ½ systolic BP.
