Fasting guidelines may be adjusted in which patient groups?

• A. Pregnancy, diabetes, and pediatric patients
• B. Only pregnant patients
• C. Only diabetic patients
• D. No adjustments

Answer: (A)

Fasting guidelines are tailored for groups with unique risks to avoid complications during anesthesia and surgery and to keep metabolism stable.

In pregnant patients, the balance between preventing aspiration and maintaining maternal-fetal health can require adjustments. Conditions like gestational diabetes or planned obstetric procedures, as well as the overall physiological changes of pregnancy, may prompt changes to the usual fasting times and fluid allowances to reduce dehydration or ketosis while still protecting the airway.

For patients with diabetes, the perioperative glucose balance is a major concern. Fasting without careful adjustment can lead to hypoglycemia if insulin or other agents are continued, or hyperglycemia and ketosis if they’re withheld. Management often involves modifying antidiabetic regimens and using IV fluids with glucose or insulin as needed, along with frequent glucose monitoring, so fasting is managed within a tight metabolic safety window.

Pediatric patients require special consideration because children have different metabolic reserves and can become hypoglycemic more quickly during longer fasts. Their hydration needs are higher relative to body size, and fasting schedules are adapted to their age, weight, and readiness for oral intake, with attention to preventing dehydration and electrolyte imbalances.

So, fasting guidelines may be adjusted in pregnancy, diabetes, and pediatric patients, reflecting the need to tailor perioperative plans to safety and metabolic stability in each group.
