Shock index and pediatric specific shock index<\/span><\/h2>\n

Shock index<\/a> is a simple bedside measure introduced by Allgower and associates [1] as early as 1967. Shock index is the ratio of heart rate to systolic blood pressure. Normal range of shock index is between 0.5 and 0.7 in healthy adults<\/span>. Shock index of 1.0 or more indicates a poor prognosis in acute circulatory failure.<\/span><\/p>\n

Shock index of >0.9 predicts mortality in adult trauma patients. Acker SN and colleagues have developed a pediatric specific shock index: SIPA: Shock index, pediatric age adjusted [2]. SIPA is defined by maximum normal heart rate and minimum normal systolic blood pressure by age. The cut off for children were:<\/p>\n

Age 4-6: >1.22
\nAge 7-12: >1.0
\nAge 13-16: >0.9<\/p>\n

In their retrospective review of around five hundred and fifty children presenting with trauma, 50% had a shock index >0.9, but age adjusted SIPA was above cut off only in 28%. SIPA showed better correlation with injury severity score (ISS), blood transfusion within first 24 hours, grade III liver\/spleen laceration requiring blood transfusion and in-hospital mortality.<\/p>\n
