Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Lactated Ringer's and Dextrose 5% is a crystalloid solution that provides fluid, electrolytes, and calories. Lactate is metabolized to bicarbonate in the liver, providing buffering capacity. Dextrose is metabolized to carbon dioxide and water, providing energy. The solution expands extracellular fluid volume and replaces electrolyte deficits.
Dextrose is a simple sugar that provides a source of calories and fluid for intravenous administration. It increases blood glucose levels, enhancing cellular metabolism and energy production via the glycolytic pathway and subsequent oxidative phosphorylation.

Intravenous infusion; adult dose is 500-1000 m L at a rate of 5-10 m L/kg/hour, adjusted based on clinical response, fluid status, and serum glucose/electrolytes. Usual max rate 30 m L/kg/day or 2000 m L/day unless otherwise indicated.
Intravenous infusion. Typical adult dose is 500-1000 m L of 7.7% dextrose solution infused at a rate of 100-200 m L/hour, titrated to clinical response and serum glucose levels.
Lactate: ~1.5 hours (hepatic conversion); dextrose: ~0.5 hours (insulin-dependent); prolonged in hepatic or renal impairment.
30-60 minutes for blood glucose to return to baseline after infusion cessation; clinical context: rapid metabolism via glycolysis.
Lactate is primarily metabolized to bicarbonate in the liver; dextrose is metabolized via glycolysis and oxidative phosphorylation to carbon dioxide and water.
Dextrose undergoes glycolysis and enters the Krebs cycle to produce ATP. It is metabolized via the Embden-Meyerhof pathway and the pentose phosphate pathway. Insulin facilitates cellular uptake.
Lactate: primarily hepatic metabolism to bicarbonate; renal excretion minimal (<5%). Dextrose: metabolized to CO2 and water; <1% excreted unchanged in urine. Electrolytes: renal excretion proportional to intake.
Renal: 100% as CO2 and water; no unchanged dextrose excreted in urine under normal conditions.
None significant (<1%); lactate, dextrose, and electrolytes are not protein bound.
None (0%); dextrose does not bind to plasma proteins.
Lactate and dextrose distribute into total body water: approximately 0.5 L/kg; electrolytes (Na+, Cl-, Ca2+) distribute into extracellular fluid: 0.2 L/kg.
0.15-0.25 L/kg; approximates extracellular fluid volume.
Intravenous: 100% (only route of administration).
Oral: 100% (dextrose is completely absorbed).
Contraindicated in anuria. For GFR 10-50 m L/min: use with caution; monitor fluid balance, electrolytes, and glucose. For GFR <10 m L/min: avoid due to risk of hyperkalemia and volume overload. No specific dose reduction equation; adjust rate based on renal function.
No specific dose adjustment for GFR; however, monitor fluid balance and serum glucose in patients with renal impairment due to risk of fluid overload and hyperglycemia.
No standard Child-Pugh based dose adjustment. Use with caution in severe hepatic impairment due to altered lactate metabolism; monitor lactate levels and avoid in severe liver failure.
No specific dose adjustment for Child-Pugh class; monitor serum glucose closely in patients with hepatic impairment due to altered glucose metabolism.
Neonates and infants: 10-20 m L/kg per dose as intravenous infusion; rate not to exceed 5 m L/kg/hour. Children: 5-10 m L/kg/hour, max 30 m L/kg/day or 2000 m L/day. Adjust based on glucose monitoring.
Intravenous infusion at a dose of 5-10 m L/kg of 7.7% dextrose solution, infused at a rate not to exceed 0.5-1 g/kg/hour of dextrose, with careful monitoring of serum glucose.
Elderly: initiate at lower end of dosing range (e.g., 500 m L initial infusion), monitor for fluid overload, hyperglycemia, and electrolyte disturbances due to decreased renal and cardiac reserve. Typical rate: 5 m L/kg/hour max.
Use with caution; consider lower infusion rates and volumes due to decreased renal function and increased risk of fluid overload and hyperglycemia. Monitor serum glucose and electrolytes frequently.
No FDA black box warnings.
No black box warning.
Use with caution in patients with heart failure, renal impairment, or conditions with sodium retention.,Monitor serum electrolytes, fluid balance, and acid-base status.,Avoid in patients with lactic acidosis or severe metabolic alkalosis.,Do not administer simultaneously with blood through same infusion set due to risk of hemolysis.
Use with caution in patients with diabetes mellitus or glucose intolerance; may cause hyperglycemia,Monitor serum glucose levels during administration,Risk of fluid overload in patients with renal or cardiac impairment,Avoid extravasation; can cause tissue necrosis,High concentrations may cause hyperosmolality and osmotic diuresis
Hypersensitivity to any component,Hyperlactatemia or lactic acidosis,Severe metabolic alkalosis,Patients with impaired lactate metabolism (e.g., severe hepatic insufficiency)
Hyperglycemia or diabetes mellitus when uncontrolled,Intracranial or intraspinal hemorrhage (contraindicated for certain dextrose-containing solutions),Known allergy to dextrose or corn products,Severe dehydration with anuria,Delirium tremens in patients with known ethanol intolerance (for high-concentration solutions)
No specific food interactions; however, dextrose content may affect blood glucose levels, requiring adjustments in diabetic patients; avoid excessive alcohol consumption due to potential electrolyte disturbances.
No specific food interactions. However, because this is a parenteral solution, oral intake may be restricted per clinical condition. Monitor blood glucose levels closely if oral intake is resumed.
Lactated Ringer's and dextrose 5% is a crystalloid solution. No teratogenic effects are reported. In first trimester, use only if clearly needed. Second and third trimesters: no known fetal risk, but monitor maternal glucose and electrolytes due to dextrose load.
Dextrose is a physiological nutrient; at standard infusion rates, no teratogenic effects are expected. However, hyperglycemia from excessive infusion may increase the risk of fetal macrosomia, neonatal hypoglycemia, and congenital anomalies (first trimester). Avoid maternal hyperglycemia.
Compatible with breastfeeding. Dextrose and electrolytes are normal blood constituents. No M/P ratio available. Use usual precautions for IV fluids.
Dextrose is a normal blood constituent; no significant excretion into breast milk. M/P ratio not applicable. Safe during breastfeeding when used at recommended doses; monitor for maternal hyperglycemia.
No routine dose adjustments needed. However, pregnancy increases blood volume and GFR; monitor for fluid overload in preeclampsia or cardiac disease. Adjust dextrose in gestational diabetes.
No specific dose adjustment required for dextrose itself. However, pregnant patients may have altered glucose metabolism; adjust infusion rate to avoid hyperglycemia or hypoglycemia. Monitor for gestational diabetes.
Contains 5% dextrose and isotonic lactated Ringer's solution; provides ~170 kcal/L from dextrose; use with caution in lactic acidosis as lactate may worsen acidosis; not compatible with certain drugs (e.g., ceftriaxone); monitor serum potassium and calcium in patients with renal impairment; do not administer with blood products due to calcium content causing coagulation.
Dextrose 7.7% is a hypertonic solution (approx. 770 m Osm/L) that must be administered via a central venous line to avoid phlebitis. It is commonly used as a component of parenteral nutrition or for treatment of hypoglycemia. Monitor serum glucose closely; rapid infusion can cause hyperglycemia and osmotic diuresis. Do not administer if solution is cloudy or contains precipitate.
