Registration Number

Brief Summary

The incidence of diabetes mellitus type II is increasing. More and more patients who need surgery have diabetes mellitus type II. Despite an enormous amount of glucose lowering protocols and the proven negative effects of hyperglycaemia. There is no evidence for the optimal glucose lowering protocol.

This study investigates the optimal intraoperative treatment algorithm to lower glucose in patients with diabetes mellitus type 2 undergoing non-cardiac surgery, comparing intraoperative glucose-insulin-potassium infusion (GIK), insulin bolus regimen (BR) and GLP-1 (liraglutide, LG) treatment.

Detailed Description

Diabetes mellitus is associated with poor outcome after surgery. The prevalence of diabetes in hospitalised patients is up to 40%, meaning that the anaesthesiologist will encounter a diabetes patient in the operating room on a daily basis. Multiple protocols for perioperative glucose regulation have been developed, ranging from intravenous glucose-insulin-potassium infusion to subcutaneous bolus regimens. Despite this abundance of published glucose lowering protocols and the proven negative effects of intraoperative hyperglycaemia in diabetes, there is no evidence regarding the optimal intraoperative glucose lowering treatment. Recently, incretins have been introduced to lower blood glucose. The main hormone of the incretin system is glucagon-like peptide-1 (GLP-1). GLP-1 increases insulin and decreases glucagon secretion in a glucose-dependent manner, resulting in low incidence of hypoglycaemia. This study investigates for the first time the optimal intraoperative treatment algorithm to lower glucose in patients with diabetes mellitus undergoing non-cardiac surgery.

Objective:

This study investigates the optimal intraoperative treatment algorithm to lower glucose in patients with diabetes mellitus type 2 undergoing non-cardiac surgery, comparing intraoperative glucose-insulin-potassium infusion (GIK), insulin bolus regimen (BR) and GLP-1 (liraglutide, LG) treatment.

Arm && Interventions
GroupInterventionDescription
BR (bolus regimen)Insulin bolus* Day before surgery: half evening dose long acting insulin * Day of surgery: * patients using mealtime and longacting insulin/NPH: withhold mealtime morning dose, stop glucose lowering tablets * patients using only long acting insulin/NPH: half dose of long-acting or NPH insulin, stop glucose lowering tablets * Measure blood glucose every 60 minutes, start 30 min prior to surgery * Give bolus of insulin according to treatment algorithm
LG (Liraglutide)Insulin bolus* Day before surgery: half dose of long acting and mealtime insulin from start liraglutide * Day of surgery: withhold own insulin, stop oral glucose lowering tablets * Start with 0.6 mg liraglutide subcutaneously (s.c.) the day prior to surgery at 17.00hr. * In case of nausea graded higher than minimal, the patient will be excluded from the study * Otherwise, treatment will be continued with 1.2 mg liraglutide s.c. per day on the day of surgery at 07.00hr. * Measure glucose every 60 minutes, start 30 min prior to surgery * Adjust according to bolus algorithm of BR group
GIK (glucose -insulin - potassium) infusionGIK infusion* Day before surgery: half evening dose long acting insulin * Day of surgery: stop oral glucose lowering tablets and withhold own insulin. * GIK infusion: 500 cc glucose 5% with insulin and 10 mmol KCL per 500 cc. Start at 83 ml/hr. * Calculate the insulin amount in the GIK infusion according to the formula: I= (PG-7)/(200/W)+8 I=Insulin amount, PG=glucose 30 minutes preoperative, W= body weight in kg * Measure blood glucose every 60 minutes, start 30 min prior to surgery * Adjust glucose \> 8 mmol/l according to treatment algorithm
LG (Liraglutide)Liraglutide* Day before surgery: half dose of long acting and mealtime insulin from start liraglutide * Day of surgery: withhold own insulin, stop oral glucose lowering tablets * Start with 0.6 mg liraglutide subcutaneously (s.c.) the day prior to surgery at 17.00hr. * In case of nausea graded higher than minimal, the patient will be excluded from the study * Otherwise, treatment will be continued with 1.2 mg liraglutide s.c. per day on the day of surgery at 07.00hr. * Measure glucose every 60 minutes, start 30 min prior to surgery * Adjust according to bolus algorithm of BR group
