Q: At what threshold of serum glucose should insulin therapy be initiated among patients requiring intensive care?
A: Pending more data to guide the identification of optimal glucose levels, national associations recommend that insulin therapy be initiated once glucose exceeds a threshold of 180 mg per deciliter.
Q: According to most professional guidelines, what should the target serum glucose be among intensive care patients receiving insulin therapy?
A: Most professional societies recommend a target glucose level of 140 to 180 mg per deciliter for patients requiring intensive care, with the use of an established, preferably computerized insulin-infusion algorithm and close monitoring of glucose levels.
