Case Reports
Fatal neuroglycopaenia after accidental use of a glucose 5% solution in a peripheral arterial cannula flush system.
A patient on an Intensive Care Unit who was recovering from multiple organ failure was being given an intravenous infusion of insulin to maintain normoglycaemia. On her 20th day in the unit, she suddenly became unresponsive. A cerebrovascular accident was suspected as other clinical and laboratory parameters remained normal apart from a blood glucose value of 20.6 mmol.l(-1). ⋯ The prolonged period of severe hypoglycaemia led to neuroglycopaenia and irreversible brain injury. The patient died 9 days later without regaining consciousness. Such a complication has not previously been reported in this context and has particular significance given the increasing use of insulin therapy to maintain normoglycaemia in critically ill patients.
