It is current practice for high amounts of sodium to be
administered, but the clinical impact is unknown. In a
single-centre study, we reported that critically ill patients
were inadvertently administered more than twice5 the
recommended sodium intake of 100 mmol/day,6 despite
achieving a fluid balance consistent with the conservative
arm of the Fluids and Catheters Treatment Trial study.1 This
was confirmed in a point prevalence study across 40
intensive care units and 356 patients in Australia and New
Zealand, in which the median total sodium administered on
the study day was 225 mmol
