Which statement accurately describes the glucose content of IV fluids used for neonates and pediatric patients during anesthesia?

• A. IV isotonic crystalloid solution with 5% dextrose
• B. Normal saline without dextrose
• C. Hypotonic solution without dextrose
• D. Hypertonic saline

Answer: (A)

Maintaining a steady blood glucose level during anesthesia is crucial in neonates and young children because their stored glycogen is limited and they can become hypoglycemic quickly if fluids don’t provide a glucose source. Therefore, the IV fluids given intraoperatively often include dextrose while remaining isotonic to preserve fluid and electrolyte balance. An isotonic crystalloid containing 5% dextose supplies the necessary glucose without shifting fluids abnormally, helping prevent hypoglycemia in these patients. Normal saline without dextrose provides no glucose, which makes hypoglycemia more likely during prolonged anesthesia or fasting. Hypotonic solutions can raise the risk of hyponatremia and fluid imbalance, and hypertonic saline isn’t routinely used for glucose maintenance.
