title: Strong ion gap in cardiogenic shock - the calculation seems wrong.
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.'
