Introduction
The target blood glucose range for critically ill patients depends on whether they have diabetes. For critically ill patients without diabetes, the recommended blood glucose range is 6.1 mmol/L to 7.8 mmol/L. For those with pre-existing diabetes, a more lenient glucose control is advised, typically within the range of 6.1 mmol/L to 11.1 mmol/L.
The target blood glucose range for critically ill patients is between 6.1 mmol/L and 7.8 mmol/L, or between 6.1 mmol/L and 11.1 mmol/L, depending on whether the patient has diabetes. The specific analysis is as follows:
1. Non-diabetic critically ill patients
For non-diabetic critically ill patients, blood glucose should be maintained between 6.1 mmol/L and 7.8 mmol/L. Excessively strict glucose control generally does not provide benefits. Some non-diabetic critically ill patients may develop stress-induced hyperglycemia, an acute and transient elevation in blood glucose that can trigger harmful pathophysiological responses. Proper management of hyperglycemia in critical illness is highly significant and can reduce patient mortality risk.
2. Diabetic critically ill patients
For critically ill patients with pre-existing diabetes, a more relaxed blood glucose target is recommended, typically between 6.1 mmol/L and 11.1 mmol/L. However, close monitoring of the patient's condition remains essential. Maintaining blood glucose within an appropriate range helps protect organ function and ensures patient safety.
It should be noted that diabetic critically ill patients are at higher risk of hypoglycemia compared to non-diabetic critically ill patients, which may increase mortality risk. Therefore, monitoring blood glucose levels is particularly important.
