Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Early Metabolic Resuscitation: After initial shock treatment including fluids and a first intravenous inotrope patients receive concomitant treatment with Hydrocortisone, Vitamin C, and Thiamine:
1. Ascorbic acid (Vitamin C). The dosing schedule is 30mg/kg intravenously every 6 hours for the duration of study treatment and will be infused over 1 hour.
2. Thiamine (Vitamin B1): The dosing schedule is 4mg/kg intravenously every 12 hours for the duration of study treatment and will be infused over 1 hour.
3. Hydrocortisone: The dosing schedule is 1mg/kg intravenously every 6 hours for the duration of study treatment given as a slow bolus.
Study drugs will be given through an existing intravenous line using. Drug delivery will occur through guardrails or similar system to ensure safe delivery of applied standardized drug concentrations.
Study treatments will be given for a duration of 7 days, or until resolution of shock, discharge from intensive care unit, death, 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.

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 total of three medications in an acute care situation, 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 randomisation. A permuted block randomisation method with variable block sizes of 2, 4 and 6 and stratified by site will be used to allocate eligible patients to the treatment group.
All eligible patients will be enrolled as soon as possible after fulfilling the criteria for randomisation. Patients will be allocated in a 1:1 ratio to the treatment group (receiving early metabolic resuscitation versus standard shock 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.

Summary
Brief summary
This multicentre pilot pragmatic open label randomized controlled Trial (RCT) compares early metabolic resuscitation treatment with Hydrocortisone, Vitamin C, and Thiamine in comparison to standard care defined as no treatment with Hydrocortisone, Vitamin C, and Thiamine. We hypothesize that in children presenting with sepsis and septic shock early intravenous administration of Vitamin C (30mg/kg iv q6h), Thiamine (4mg/kg q12h) and Hydrocortisone (1mg/kg q6h) delivered early during resuscitation is feasible. We hypothesize that these interventions will lead to a more rapid resolution of shock, reduced duration of organ dysfunction, leading to reduced intensive care resource utilisation.
The study can provide the urgently needed evidence on currently used sepsis resuscitation bundles.
