Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1 - Plasma-Lyte - 148
Arm 2 - Compound Sodium Lactate solution

Parent information leaflet with consent forms will be provided. The staff will be informed about the two intervention fluid arms.
The intervention will be provided individually after consent.
The research coordinator will screen and consent patients/parents. Once recruited, the junior doctor will be adviced to prescribed the appropriate intravenous fluid therapy as per randomisation. The bedside nurse will administer the intervention fluid therapy as directed by the clinician.
The amount, rate and duration of maintenance fluid and bolus therapy will be dictated by the attending clinician as per institutional protocol. The institutional protocol aligns with international practice on administering intravenous maintenance fluid therapy. Therefore, maintenance fluid requirements are calculated at 4ml/kg/hr for the first 10 kgs, 2ml/kg/hr for next 10 and 1 ml/kg/hr there after according to the weight of the child.
As our primary outcome is a biochemical end-point, we will need blood gases on admission, during PICU stay and at discharge. These will amount to 4 samples if the patient was in PICU for 2 days (usually length of stay for most PICU patients).
Blood gases will be preferentially taken from an already in-situ arterial or venous line and be collected along with routine morning bloods where appropriate. If there are no invasive lines present and the peripheral venous cannula does not bleed back, a capillary blood gas sample will be taken. This is expected to be needed in a minority of patients.

The children will be part of the trial until discharge from Paediatric Intensive Care Unit (PICU) or cessation of intravenous fluid therapy (whichever is earlier). The intervention will only occur on the PICU and be administered until discharge from PICU. The expected duration of intervention is estimated to be around 3-5 days ( around the median PICU length of stay).
All interventions will be assessed retrospectively by automated data collection on a monthly basis to ensure adherence to prescription and study protocol.

Sample size calculation:
A recently published article reported an incidence of the rise in chloride level of greater than or equal to 5mmol/L of 12.5% at the end of day 1. Based on a review of our institutional PICU retrospective data, we expect the proportion of children admitted to PICU that has a rise in chloride level of greater than or equal to 5mmol/L to be about 20% by 48 hours. To demonstrate a 10% reduction in the incidence of this primary outcome (5% alpha and 80% power), we will need 432 patients with a 1:1:1 allocation between 0.9% Sodium Chloride and each of the balanced solutions. Plasma-Lyte and Compound Sodium Lactate solution will be equally randomised. To account for a 10% attrition, we have decided to recruit 480 patients. We will complete an interim analysis after 250 patients to assess the power and estimate more accurate sample size.
After we account for the loss of recruits due to exclusions, those receiving no intravenous fluid therapy and missed randomisation, we expect to achieve our target within a 12-month study period. The QCH PICU on average admits 160 patients per month. Assuming 80% of patients will receive IVFT, and 40% drop-out because of meeting exclusion criteria, and 50% consent rates, recruitment of at least 40 patients per month is a realistic target.
Descriptive statistics will be used to report on the baseline characteristics of the total study cohort, each intervention group and the pre-defined subgroups. Associations between treatment group and outcomes will be explored using appropriate techniques, such as chi-squared (or Fisher’s Exact Test if there are low numbers of outcomes), ANOVA or Kruskal-Wallis.
Where there are repeat admissions to PICU, patients are eligible for re-randomisation if the readmission is after 28 days of the previous PICU discharge.
A priori subgroup analysis for primary outcome:
1. Age at PICU admission: less than or equal to 6 months, greater than 6 months to less than or equal to 5 years, greater than 5 years to less than 16 years
2. Elective/Non-elective
3. Patients who received IVFT >24 hours
4. Patients who received IVFT less than or equal to 24 hours
5. Patients who received IVFT >50ml/kg

Summary
Brief summary
Hypothesis:
Balanced fluids (Plasma-Lyte and Compound Sodium Lactate) will lower the prevalence of high chloride rise (greater than or equal to 5mmol/L) compared to 0.9 % sodium chloride solution.

Study design:
Single centre, open label, randomised controlled trial.
Intervention:
Random assignment of individual patients (less than 16 yrs) into three groups – 0.9% Sodium Chloride solution, Plasma-Lyte 148 (PL) and Compound Sodium Lactate solution (CSL).
