Association between dextrose-containing maintenance fluids and phosphorus supplementation during total parenteral nutrition initiation in adult patients who were hospitalized: A retrospective cohort study.

Background: Use of dextrose-containing maintenance fluids prior to parenteral nutrition (PN) initiation is speculated to reduce the risk for refeeding syndrome. We aimed to assess if the use of dextrose vs nondextrose maintenance fluids before PN initiation changes electrolyte supplementation requirements and shifts during initiation.

Methods: This retrospective cohort study included patients who received nothing by mouth but received maintenance fluids ≥72 h before PN.
