Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* The study evaluates a target controlled insulin infusion or conventional therapy as antidiabetic treatment during ulcer infection and after cardio- vascular surgery.
* Secondary efficacy parameter will be hospital stay, laboratories for inflammation and oxidative stress.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Normoglycemia is important for the outcome of acute surgical and medical conditions. Different insulin infusions have been studied to achieve normoglycemia and have proved to be useful. Insulin given by subcutaneous injections has duration between 3- 36 hours depending on the insulin brand and injection site compared to 10 minutes for intravenous given insulin. Different insulin infusions have been studied to achieve normoglycemia but the biological and chemical effects of insulin infusions have not been studied in routine operative care of patients with diabetes. Therefore, we aim to investigate the importance of normoglycemia for the optimal treatment of ulcer infection and/ or during routine cardio- vascular surgery care among diabetics.
Hypothesis:
Target controlled insulin infusion is more effective in reducing hyperglycemia, improve healing of inflammation and infection in diabetics compared to conventional antidiabetic therapy.
The infusion starts when patients who met the eligibility criteria has signed the informed consent. The intervention group continues for tree full days with insulin infusion. After the transition day (the fourth day) multiple doses of mixinsulin continues until the study ends 4 weeks after the randomization.
Study Design:
This is a randomized prospective, open controlled trial of target controlled insulin infusion vs conventional antidiabetic therapy in diabetic patients. Diabetics planned treated for ulcer infection and/ or after elective cardio- vascular surgery, who met inclusion, not exclusion criteria and choose to participate will be included and randomized.
Duration of study:
The infusion starts when patients who met the eligibility criteria have signed the informed consent and for the surgery group prior the surgery the operation day for all patients and stops during the postoperative care in the control group (conventional therapy). The intervention group continues for three full days with insulin infusion. After the transition day (the fourth day) multiple doses of mixinsulin continues until the study ends 4 weeks after the randomization.
Selection of patients:
Patients with diabetic ulcer infection and/or planned cardio-vascular intervention will be enrolled.
Treatment:
Eligible patients will be randomized to insulin infusion (group 1) for 3 days or therapy according to clinical practise (group 2).
Group 1 (intervention group):
The insulin infusion starts when the patients full fill the eligibility criteria, has signed the informed consent and for the surgery group prior the start of the operation. It controls by regular capillary plasma glucose tests and continues for three days. The infusion stop on the fourth day, the insulin demand is estimated from the last 24 infusion hours by a specific algorithm and divided to 2-4 equal mealtime doses of mixinsulin. The first mealtime dose is given to the breakfast on the fourth day and the infusion continues for another 2 hours where after it is stopped. After the transition day (the fourth day) multiple doses of mixinsulin continues until the study ends 4 weeks after the randomization.
All patients will have a stop visit at the study end.

Study Groups

Insulin infusion (aspart)
Insulin infusion
The infusion, a fast acting insulin analog in 1 Unit/ml of NaCl, starts prior the surgery the operation day for all patients and stops during the postoperative care in the control group (conventional therapy), the intervention group continues for three full days with insulin infusion. After the transition day (the fourth day) multiple doses of mixinsulin continues until the study ends 4 weeks after the randomization.
Standard care
Glucose control according to standard care at the ward, i.e., sliding scale insulin at the discretion of responsible physician.
