Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Recovering critically ill patients who meets the study inclusion criteria will be given insulin glargine once a day. The dose will be determined by a titration algorithm. Blood samples will be taken for assays of plasma insulin and C-peptide 3 times a day for the first two days a patient is receiving glargine. The samples will be taken before glargine injection, 6 hours from time of injection, and 14 hours from time of injection. The patient will continue to receive glargine for blood glucose control unless the dose become less than 10U. When the patient begins to consume meals (as oppose to naso-gastric feed), blood samples will be taken 8 times a day for the first two days. These samples will be taken before glargine injection and breakfast, before lunch, before dinner, 30 mins from start of dinner, 1 hr from start of dinner, 1.5 hrs from start of dinner, 2 hrs from start of dinner, and 4 hrs from start of dinner. Photos will be taken of the meal before and after mealtime to determine nutrition intake.

Eligibility
Key inclusion criteria
- Stable hourly insulin requirement, equal to or less than 3U of intravenous insulin per hour, for at least 12 hours.

- No acute renal failure (creatinine < 250 micromol/L)
- Less than 1000ml of fluid given as intravenous boluses in the past 24 hours, indicating stable interstitial volume.
- Resolving multiple organ failure (Sequential Organ Failure Assessment Score SOFA<=6).
