Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: Early Inotropes:
Early Inotropes: Goal-Directed Therapy with initiation of intravenous inotropes after the initial fluid bolus (20ml/kg, minimal amount 10-20ml/kg fluid bolus; (or 500-1000ml fluid bolus in patients >50kg). The inotrope used is diluted adrenaline initiated at 0.05 to 0.1 (up to 0.3) mcg/kg/min. Dilution is used to fasten drug delivery and response to drug rate changes, to reduce risks with extravasation, and to facilitate peripheral application. Adrenaline will be prepared in 50ml syringes in 5% Dextrose solution that will be connected to peripheral, intraosseus, or central vascular access device. Drug delivery will occur through guardrails or similar system to ensure safe delivery of applied standardized drug concentrations.

The study treatment will be given as continuous infusion for the duration of resuscitation until resolution of shock, discharge from intensive care unit, death, decision of the treating physician to stop or replace with other inotrope, or occurrence of major side effects, whichever occurs first.
Compliance with protocol will be assessed through the prospective institutional drug charts, and the prospective study case report form
Intervention code [1] 314617 0
Treatment: Drugs
Comparator / control treatment
Standard Care:
Early Goal-Directed Therapy as per the institutional practice aligned with the most recent edition of the ACCCM recommendations for management of paediatric septic shock. Specifically, 40-60ml/kg of fluid will be administered prior to initating inotropes (>2-3L for patients >50kg). The inotrope used is diluted adrenaline initiated at 0.05 to 0.1 (up to 0.3) mcg/kg/min.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
No blinding will be performed, intervention will be open labelled. The main aim of this pilot study is to define the feasibility of treatment. To ensure preliminary evidence of safety can be provided, and reduce the logistic challenges with blinding it is acceptable to perform this pilot open label.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be enrolled as soon as possible after fulfilling the criteria for randomizsation. A permuted block randomizsation method with variable block sizes of 2, 4 and 6 and stratified by site will be used to allocate eligible patients to the treatment groups.
All eligible patients will be enrolled as soon as possible after fulfilling the criteria for randomizsation. Patients will be allocated in a 1:1 ratio to the treatment group (Intervention 1, receiving early inotropes versus standard fluid management).

Statistical methods / analysis
Descriptive statistics will be utilised to report on the baseline characteristics of the total study cohort and each subgroup, as well as by site. The primary outcome measure investigating days free of organ dysfunction will be analysed using a Mann-Whitney test (assuming the data is non-normally distributed). Analysis of secondary outcomes includes both comparisons of measurements and proportions, using confidence intervals of differences as the major method of presentation where possible, otherwise standard techniques such as Mann-Whitney U tests, t-tests and chi-squared tests will be utilised. Main analyses will be by intention-to-treat. Per-protocol analyses will be performed as well and compared to intention-to-treat. Statistical significance will be set at the 0.05 level for the primary outcomes. Post-hoc power analyses may be undertaken to determine if results found in sub-group analyses are reliable.
