Robust Modelling of the Glucose-Insulin System for Tight Glycaemic Control of Less Critical Care PatientsAbdul Razak, Normy Norfiza January 2012 (has links)
In the intensive care units, hyperglycaemia among the critically ill is associated with poor outcomes. Many studies have been done on managing hyperglycaemia
in the critically ill. Patients in the ICU continue to benefit from the outcome of extensive studies including several randomized clinical trials on glycaemic control
with intensive insulin therapy. Tight glycaemic control has now emerged as a major research focus in critical care due to its potential to simultaneously reduce both mortality and cost. Although the debate on tight glycaemic control is
on going, managing glycaemic level in ICUs is gaining widespread acceptance as the adverse effects are well known. However, in the less acute wards, to date there have only been a single randomized, controlled study to examine the
benefit of glycaemic control. Patients in the less acute wards do not receive the same level of care, as glycaemic control is not regarded as important and not a priority. Glycaemic goals in the less acute wards are often judged based on clinical experience rather than adhering to a standard protocol or a treatment guideline. It is important that patients in the less acute wards received the level of care as practised in the ICU. If hyperglycaemia worsens outcome in the ICU, a similar effect is seen within less acute wards. Hence, tight glycaemic control needs to be
extended in the less critical setting as well. To support the establishment of a control protocol for patients in less acute wards, a method that has been successful in the critical care and can be adapted to the less acute wards, is the model based or model-derived control protocol. Model-based protocol can deliver a safe and effective patient-specific control, which means the glycaemic control protocol
can be devised to each individual patient. Hence, a physiological model that represents the glucose-insulin regulatory system is presented in this thesis. The
developed model, Intensive Control Insulin-Nutrition-Glucose (ICING) is based on the best aspects of two previous clinically-validated glucose-insulin models.

Ets-insulin-bolus calculation promotes tighter blycaemic control for type 1 diabetics / Henry Louis TownsendTownsend, Henry Louis January 2007 (has links)
Type 1 Diabetes is a dangerous and life-long disease for which its prevalence is global. Research
has shown that tight glycaemic control of this disease significantly reduces the risks of developing
several life threatening diabetic complications.
The Ets-Insulin-Bolus Calculator (EIBC), inspired by the Ets concept (Equivalent Teaspoon
Sugar), was primarily designed to assist type I diabetics in improving their blood glucose control.
The EIBC has shown to improve the average blood glucose level of type 1 diabetics. The need for
this study however is to determine whether the ET!3C promotes tighter glycaemic control for type 1
diabetics based on a more-in-depth numerical analysis.
With the use of the latest technology in blood glucose monitoring, the CGMS from Medtronic,
mathematical models expressing and rating blood glucose control have been proposed and derived
in this study. A clinical trial with type 1 diabetics has also been conducted.
The use of the models together with the clinical trial results have shown that the EIBC does in fact
promote tighter glycaemic control for type 1 diabetics. / Thesis (M.Ing. (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2007.
