Introduction: In a majority of Spanish hospitals, serum sodium levels (SNa) are determined by indirect electrode methodology (sodium in the liquid fraction of serum) divided by the total serum volume (mmol/l). To avoid over/underestimating SNa, a formula can be applied: SNa corrected for total proteins (TP)=SNa×93 divided by (99.1−(0.7×TP)). Hypoproteinaemia is frequent in patients receiving parenteral nutrition (PN), and is probably related to surgery, acute d...

Introduction: Syndrome of Inappropriate Antidiuretic (SIAD) is the most frequent cause of hyponatremia in parenteral nutrition (PN) patients. Yet studies concerning SIAD therapy are lacking. Our objective was to describe SIAD treatment and determine pre-treatment predictors of failure to respond to fluid restriction (FR) and furosemide efficacy prediction in a group of patients with SIAD while receiving PN.Methods: Prospective, non-interventional, multic...
