Description of intervention(s) / exposure
Plasmalyte148 with 5% dextrose
Mode of administration: intravenous infusion
Rate of infusion: to be determined by the treating clinician, but must be between 50 - 150% of standard maintenance rates (based on the 100/50/20 or 4/2/1 rule).
Duration of infusion: Subjects will remain in the trial while they are receiving intravenous fluids at a rate of at least 50% maintenance, or for 72 hours (whichever is sooner).

Outcomes
Primary outcome [1] 253075 0
The primary outcome is the proportion of subjects in each treatment group that develop hyponatraemia [serum sodium measurement that is below the normal range minimum (135mmol/L) and has decreased by at least 3mmol/L compared with the baseline measurement] at any time point during the treatment period.
Timepoint [1] 253075 0
Subjects will remain in the trial while they are receiving at least 50% of standard maintenance fluid rates, or for 72 hours (whichever is sooner). They will have blood tests performed at 0, 6, 24, 48 and 72 hours, while they remain in the trial. Additional blood tests may be performed between these time points, as determined by the treating clinician. There is no maximum number of blood tests which may be performed. All blood tests performed may be used in the analysis.
Secondary outcome [1] 257918 0
The proportion of subjects in each treatment group with a measurement of hypernatraemia (serum sodium >145 with an increase of at least 3mmol/L compared with the baseline measurement) at any time during the study period.
Timepoint [1] 257918 0
Subjects will remain in the trial while they are receiving at least 50% of standard maintenance fluid rates, or for 72 hours (whichever is sooner). They will have blood tests performed at 0, 6, 24, 48 and 72 hours, while they remain in the trial. Additional blood tests may be performed between these time points, as determined by the treating clinician. There is no maximum number of blood tests which may be performed. All blood tests performed may be used in the analysis.
Secondary outcome [2] 257919 0
The proportion of subjects in each treatment group with a measurement of severe hyponatraemia (serum sodium <130 with a decrease of at least 3mmol/L compared with the baseline measurement) at any time during the study period.
Timepoint [2] 257919 0
Subjects will remain in the trial while they are receiving at least 50% of standard maintenance fluid rates, or for 72 hours (whichever is sooner). They will have blood tests performed at 0, 6, 24, 48 and 72 hours, while they remain in the trial. Additional blood tests may be performed between these time points, as determined by the treating clinician. There is no maximum number of blood tests which may be performed. All blood tests performed may be used in the analysis.
Secondary outcome [3] 257920 0
The proportion of subjects in each treatment group with a measurement of severe hypernatraemia (serum sodium >150 with an increase of at least 3mmol/L compared with the baseline measurement) at any time during the study period.
Timepoint [3] 257920 0
Subjects will remain in the trial while they are receiving at least 50% of standard maintenance fluid rates, or for 72 hours (whichever is sooner). They will have blood tests performed at 0, 6, 24, 48 and 72 hours, while they remain in the trial.

All blood tests performed may be used in the analysis.
Secondary outcome [4] 257922 0
A comparison of fluid status in each treatment group. This will be clinically assessed by the treating clinician who will state whether the subject is clinically dehydrated, euvolaemia or overhydrated. They will also record which clinical features or investigations resulted in this assessment.
Timepoint [4] 257922 0

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Initially sealed opaque envelopes. It is anticipated that an on-line enrollment program will be available within two months of the study commencing - at this point this computerised system will be used for treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be developed by a statistician using block randomisation.
