What blood glucose target is recommended in ICU patients?

NICE-SUGAR trial: glucose 140-180 mg/dL target reduces mortality vs intensive control (81-108 mg/dL) due to hypoglycemia harm; current SCCM/AACE target 140-180 mg/dL; below 140 is acceptable but below 110 is harmful.

What insulin infusion starting dose is recommended?

Typical insulin infusion algorithms start at 0.5-1 unit/hr for glucose 150-200 mg/dL; adjust by 0.5-1 unit every 1-2h based on glucose checks; glucocheck every 1-2h when unstable, every 2-4h when stable.

What blood glucose threshold requires intervention?

Glucose 250 mg/dL: escalate insulin; >350: consider DKA protocol.

What factors predispose ICU patients to hypoglycemia?

Enteral/PN nutrition interruption while insulin infusing, steroid dose reduction, sepsis resolution, renal/hepatic dysfunction, insulin-specific issues (inappropriate protocol application); high-risk patients need more frequent monitoring.

Is continuous glucose monitoring reliable in ICU?

CGM in ICU reduces time outside target range and hypoglycemia episodes in some trials; subcutaneous sensors may be less accurate in shock (poor perfusion); IV CGM sensors more reliable; not yet standard of care but promising.

ICU Glucose Control and Insulin Infusion Protocol Calculator

Implements evidence-based glucose control (140-180 mg/dL target per NICE-SUGAR) in ICU patients with insulin infusion titration, hypoglycemia risk stratification, and continuous glucose monitoring integration.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
