Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Trial participants randomised to ketone ester supplementation (R-1,3-Butanediol, 0.29grams/ml) will have this preparation administered via nasogastric tube within eight hours of ICU admission.

Dose: 40g bolus of ketone esters followed by 10g/hr NG infusion of KE for 12 hours and then cease

Adherence to the intervention will be monitored by administration documented in paper medical record and drug chart, as well as by study investigators.

Product: The KE supplement is a clear, colourless liquid solution that comes packaged in plastic bottles. It is manufactured by Health Via Modern Nutrition Inc, USA under the brand name, Ketone-IQ. It can be administered via syringe or an enteral feeding set down the participants nasogastric tube by ICU nursing or medical staff.

Comparator / control treatment
Trial participants randomised to placebo will have this administered via nasogastric tube within eight hours of ICU admission (ideally within 4 hours of hospital presentation). The placebo substance will be sterile water prepared in similar bottles by the same company.

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)
Allocation concealment will be maintained using sequential opaque sealed envelopes stored in the ICU.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will occur in a 1:1 ratio and occur as soon as possible following admission to the Intensive Care Unit. Randomisation will be derived from a computer-generated random number sequence.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The aim of this study is to determine the feasibility of giving ketone bodies in the form of dietary supplementation to patients with acute neurological injury admitted to ICU in order to improve neurological outcomes.

This study will use be a randomised controlled trial, a well known study design that eliminates study biases that can confound findings as much as possible in order to determine the true utility of the use of ketones in brain injury. Patients who are in a coma with an acute brain injury, admitted to ICU, will be eligible to participate in this trial. Participants will be randomised (like the toss of a coin) to routine administration of ketone bodies via a feeding tube on admission and standard care, or placebo and standard care alone. Ketone body supplementation is currently not available for ICU patients and will only be available within this trial.

Determining the feasibility of giving ketone bodies to patients with acute brain injury admitted to ICU is the first important step in a program of research that ultimately aims to test the efficacy of using ketone bodies in this group of patients to improve neurological outcomes and reduce disability.
