How is insulin management adjusted during labor for a pregnant patient with diabetes?

• A. Continuous insulin infusion with hourly glucose monitoring; target 70–110 mg/dL
• B. Discontinue insulin during labor
• C. Use only oral hypoglycemics during labor
• D. Administer fixed-dose IV insulin regardless of glucose

Answer: (A)

Tight glycemic control during labor is essential to protect both mother and baby, because the stress of labor can rapidly alter insulin needs and maternal glucose levels. The best approach is continuous IV insulin infusion with hourly glucose monitoring, aiming to keep maternal glucose in roughly 70–110 mg/dL. This setup lets clinicians quickly adjust insulin based on real-time glucose readings and the patient’s changing physiology under labor, while IV dextrose is often given to prevent hypoglycemia and ensure steady glucose supply. Discontinuing insulin during labor risks maternal hyperglycemia and ketosis, which can harm both mother and fetus. Using only oral hypoglycemics isn’t appropriate in the labor setting due to unreliable absorption and potential fetal extrapolation; IV insulin provides precise, rapid control. A fixed-dose IV insulin plan ignores dynamic changes in insulin sensitivity during labor and can lead to dangerous hypo- or hyperglycemia.
