Glycaemic control

Elevated blood glucose is a widely recognised response to critical illness, with around two thirds of patients admitted to the intensive care unit requiring treatment with insulin infusion therapy.

The benefits of avoiding hyperglycaemia in critically ill patients have been demonstrated and are understood, but insulin therapy carries the risk of hypoglycaemic episodes and injury. The difficulty with safely and consistently maintaining blood glucose concentrations has resulted in care protocols remaining highly variable across northwest European ICUs and 80% of intensive care units cite problems with implementing their adopted protocols.

Blood testing is at the heart of many of these issues. Frequent blood glucose monitoring is essential for optimally managing insulin therapy and protocols often require hourly measurement of blood glucose until patient stability is achieved. Any changes that could affect glucose levels, such as insulin or feed changes require reverting to hourly measurement until stability is evident.

The amount of time involved implementing protocols is a problem frequently mentioned by the clinical staff. Pressure on time can lead to testing not being carried out as frequently as necessary, or to wider target glucose levels being accepted to avoid the risk of hypoglycaemic events.

The Proxima system allows rapid measurement of glucose levels directly at the bedside, making frequent measurement of arterial blood samples easy and helping carers maintain glycaemic control.
