Why the study?
To evaluate peripheral perfusion index variation, its correlation with lactate concentration, and its diagnostic relationship with mortality in children with septic shock.
Does peripheral perfusion index correlate with lactate concentration and mortality in children with septic shock?
Does peripheral perfusion index correlate with lactate concentration and mortality in children with septic shock?
In children with septic shock, peripheral perfusion index negatively correlates with serum lactate, but a threshold of ≤0.6 at 6 hours has considerable uncertainty for predicting mortality.
PI variation correlates with lactate in pediatric septic shock; leaves open mortality prediction utility pending prospective validation.
