Study hypothesis
The hypothesize of the study is that in sick children, moderately hypotonic fluids (such as fluids contain 77 mmol/L sodium) are better tolerated (i.e. induce less hyponatraemia without the risk of hypernatraemia) than conventional intravenous fluids that contain 34 mmol/L sodium.
Ethics approval
Ethical Board of Istanbul University, Istanbul Faculty of Medicine, approved on 13 June 2005. Ref: 2005/526.

Condition
Hyponatraemia
Intervention
The patients were randomized to one of the three study arms prospectively. Stratified block randomization was performed, with each one-week block featuring a different intravenous solution. Randomization was performed separately for children on the ward and children in the Paediatric Intensive Care Unit (PICU).
Arm 1: 0.2% sodium in 5% dextrose
Arm 2: 0.3% sodium in 3.3% dextrose
Arm 3: 0.45% sodium in 5% dextrose
When hyponatraemia developed in any group during the therapy intravenous fluid sodium composition was increased and fluid therapy was decreased to 80% of the initial volume.

Primary outcome measure
Association between administration of hypotonic fluids and hospital-acquired hyponatraemia, assessed by the following:
1. Plasma sodium, potassium and osmolality in all blood samples collected at admission (T0) and 12 (T12), 24 (T24), 48 (T48) and 72 (T72) hours of intravenous fluids therapy
2. Plasma urea, creatinine and uric acid, measured in all blood samples collected at T0 and T24
Secondary outcome measures
To determine contributive factors that may increase hyponatraemia risk, assessed by the following:
1. Plasma sodium, potassium and osmolality in all blood samples collected at admission (T0) and 12 (T12), 24 (T24), 48 (T48) and 72 (T72) hours of intravenous fluids therapy.
2. Plasma urea, creatinine and uric acid, measured in all blood samples collected at T0 and T24.
3. Plasma AntiDiuretic Hormone (ADH), measured at T0. Abnormal ADH function was assessed by serum osmolality and serum sodium determinations.
