Abstract
These formulae are erroneous and lead to predictably grossly wrong results. The authors find SIG values of mean –14 mEq/l in the non-survivors’ and –10 mEq/l in the survivors’ group. ‘ According to our data the SIG approach does not seem to add further information to usual parameters in acid-base evaluation or early risk stratification in cardiogenic shocks patients.’
