About this study

Official title: Hyperglycaemia and Hyperlactataemia in Patients With Severe Acute Brain Injury in the Intensive Care Unit - a Prospective, Observational Cohort Study

This is an observational study of patients with severe acute brain injury, which aims to characterize the development of hyperglycaemia and hyperlactataemia and the influence of these markers on clinical outcome.

Additionally, in a subgroup of patients undergoing advanced multimodal neuromonitoring on either clinical or research indication, the relationship between hyperglycaemia and brain glucose levels as well as systemic and microdialysis lactate will be examined.

Being tested
Sampling of blood and cerebrospinal fluid
Medical subject headings
Brain Injuries, Hyperglycemia, Hyperlactatemia

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sampling of blood and cerebrospinal fluidOther

    Blood HbA1c, insulin, C-peptide and IL-6 measured at admission. Glucose and lactate measured every 4 hours during intensive care stay. Daily sampling of CSV analysed for glucose and lactate in patients with EVD.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Functional outcome at 6 months as evaluated by the modified Rankin Scale.

    Modified Rankin Scale ranges from 0-6, where 0 is the best and 6 is the worst outcome.

    Measured: 6 months after admission.

Secondary outcomes (2)
  1. All-cause mortality at 6 months (dichotomous).

    Measured: 6 months after admission.

  2. Length of stay in the neuro-ICU (continuous).

    Measured: Day of discharge, typically 1-30 days after admission.

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Brain Injury and Hyperglycemia, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Functional outcome at 6 months as evaluated by the modified Rankin Scale. (time frame: 6 months after admission.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
