Hypoglycemia Management
Treatment
If BG < 70 mg/dL: Administer IV dextrose 25–50 mL (D50W).
If BG < 40 mg/dL: Stop insulin + continuous glucose monitoring.
Signs & Symptoms:
•Sweating, tremors, palpitations.
•Confusion, seizures, coma (severe cases).
Preventing Hypoglycemia:
•Adjust insulin during NPO (nothing by mouth) periods.
•Ensure adequate carbohydrate intake.
•Frequent blood glucose monitoring.
Definition & Importance
Glycemic control in ICU refers to maintaining blood glucose levels within a safe range to reduce complications.
Prevents hyperglycemia, hypoglycemia, and glucose variability—all associated with poor patient outcomes.

Diagnostic Monitoring
Methods
•Capillary blood glucose (CBG) via glucometer.
•Arterial & venous blood sampling (more accurate).
•Continuous glucose monitoring (CGM) (not widely used in ICU).

Key Takeaways
•Maintain BG 100–180 mg/dL in critically ill patients.
• IV insulin is the preferred therapy in ICU.
•Frequent BG monitoring to prevent hypoglycemia.
•Avoid oral hypoglycemics & aggressive glucose lowering.
•Adjust insulin therapy during enteral feeding or fasting periods.
