Description détaillée
Before the beginning of any trial related activities, the relatives of each patient will be asked if the patient has ever mentioned in the past, that he/she does not want do participate in any kind of clinical study. If this was said by the patient in the past or if there are any signs which make it likely that the patient would not participate, he/she will be excluded from the trial. After testing of the inclusion and exclusion criteria, screening information will be obtained a the beginning of the trial. A screening number will be assigned to the patient in ascending order. The following data will be recorded in the case record form (CRF): Check for inclusion/exclusion criteria,demographic data, medical (including diabetes) history and relevant medication, body weight and heightand laboratory analyses from routine laboratory assessment. Patients fulfilling all the inclusion criteria and none of the exclusion criteria will be included into the trial and a subject number will be assigned in ascending order. Routine intensive care will be provided from department of internal medicine. Trial related activities will not interfere with regular patient care. Blood samples will be retrieved from an arterial line, available for routine diagnostic and monitoring procedures in all patients. At time 0, a blood glucose measurement will be taken, manually entered into the CS-1 decision support system and both a insulin infusion rate and the time to next glucose reading will be suggested by the computer-based system. Based on the suggestion of the system, an insulin infusion pump as routinely used in the ICU will be manually set to this suggested insulin infusion rate by specially trained ICU staff but only if the staff feels safe with this suggestion. Intravenous infusion of human soluble insulin will then be started. For safety reasons: In case that the suggested measurement interval of the decision support system exceeds a 90 minute interval, interim glucose measurements will be taken. All measurements will be documented in the CRF. Only in case that the blood glucose values are below 40 mg/dl the additional interim-glucose value will also be put into the CS-1 system. However, the nursing staff can at any time decide to take an additionlal blood glucose measurement and/or neglect the decision as suggested by the system.
The target range for blood glucose levels will be 80-110 mg/dl [4.4 - 6.1 mmol/l]. The current blood glucose level and insulin infusion rate will continuously be documented by the CS-1 decision support system and supervised by the investigator. Glucose values will be provided to the system by manual entry. In case of hypoglycaemia, intravenous insulin infusion will be stopped and glucose will be administered via intravenous bolus.
The treatment visit, including all trial related activities as described above, will last for 72 hours. Adverse events and relevant medication will be continuously monitored and documented The Acute Physiology and Chronic Health Evaluation Score (Apache II) will be documented for each patient at the beginning of the trial. There is no physical connection between the algorithm suggesting the insulin infusion rate and the insulin infusion pump such as that the algorithm would be capable to independently steer the insulin infusion. There is also no physical connection between the glucose measurement device and the algorithm such as that the algorihthm would be able to independently get a glucose measurement. For safety reasons, both the glucose measurement and the insulin infusion rate are parameters that need to be manually entered by a specially trained nurse. For glucose measurement, a certified device for ICU application is being used (Accuchek® Inform; Roche Diagnostics), for intravenous insulin infusion, a certified insulin infusion pump (Perfusor® Space, BBraun Melsungen) as it is used under routine conditions in the ICU is being used. Follow up information will be acquired at hospital discharge or at the latest one week after visit 1. .
