Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Dextrose provides glucose for cellular metabolism, serving as a source of calories and energy. Lactated Ringer's solution supplies electrolytes (sodium, potassium, calcium, chloride) and lactate, which is metabolized to bicarbonate to buffer acidosis.
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.

Intravenous infusion, typical adult dose is 1000 m L to 3000 m L per 24 hours, rate adjusted based on fluid and electrolyte needs.
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.
Terminal elimination half-life of dextrose is approximately 1.5-2 hours in healthy adults; clinically, redistribution occurs faster due to cellular uptake, but elimination depends on glucose homeostasis and renal function.
Lactate: ~1.5 hours (hepatic conversion); dextrose: ~0.5 hours (insulin-dependent); prolonged in hepatic or renal impairment.
Dextrose: metabolized via glycolysis and oxidative phosphorylation in tissues; lactate: converted to bicarbonate in the liver via gluconeogenesis.
Lactate is primarily metabolized to bicarbonate in the liver; dextrose is metabolized via glycolysis and oxidative phosphorylation to carbon dioxide and water.
Renal: nearly 100% as intact dextrose and water; lactated Ringer's components (Na+, K+, Ca2+, Cl-, lactate) are excreted renally or metabolized (lactate to bicarbonate). Biliary/fecal: negligible.
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.
<5% bound; dextrose does not significantly bind to plasma proteins; lactate and electrolytes are minimally protein-bound.
None significant (<1%); lactate, dextrose, and electrolytes are not protein bound.
Approximately 0.2-0.25 L/kg (dextrose distributes mainly in extracellular fluid, but is rapidly taken up by cells); clinical interpretation: initial distribution to ECF, then intracellular uptake.
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.
Intravenous: 100% bioavailability; not applicable orally as the preparation is for IV use only.
Intravenous: 100% (only route of administration).
Use caution in renal impairment; monitor fluid and electrolyte status. No specific GFR-based dose adjustment formula; adjust volume and rate based on renal function.
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 Child-Pugh based adjustment; monitor for fluid overload and electrolyte imbalances.
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.
Intravenous infusion, dose based on weight and clinical condition. Typical rate: 4-8 mg/kg/min of dextrose (equivalent to 5-10 m L/kg/hour of this solution for fluid maintenance, adjust as needed).
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.
Use with caution; monitor renal function and avoid fluid overload. Adjust infusion rate based on cardiovascular status and comorbidities.
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.
None.
No FDA black box warnings.

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.

Hypersensitivity to any component,Hyperlactatemia or lactic acidosis,Severe metabolic alkalosis,Patients with impaired lactate metabolism (e.g., severe hepatic insufficiency)
No known food interactions. However, monitor glucose intake from other sources if diabetic. Avoid high-potassium foods if hyperkalemia risk.
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.
Dextrose and lactated Ringer's solution components are generally considered low risk for teratogenicity. Dextrose is a normal constituent of blood and essential for fetal growth. No evidence of structural anomalies from intravenous administration. Lactated Ringer's components (sodium, chloride, potassium, calcium, lactate) are physiological and not associated with teratogenic effects. However, hyperglycemia from excessive dextrose may be associated with fetal macrosomia and neonatal hypoglycemia if maternal glucose control is poor. No trimester-specific risks beyond those related to maternal fluid and electrolyte balance.
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 and lactated Ringer's components are normal constituents of breast milk. Exogenous administration at pharmacological doses is expected to result in minimal transfer. Dextrose is rapidly metabolized; its concentration in milk is not significantly increased. Lactate is a normal milk component. No specific M/P ratio available. Considered compatible with breastfeeding, but use only if clearly needed and monitor infant for signs of fluid or electrolyte imbalance if high volumes are administered.
Compatible with breastfeeding. Dextrose and electrolytes are normal blood constituents. No M/P ratio available. Use usual precautions for IV fluids.
Dextrose-containing solutions should be used with caution in pregnancy due to increased risk of hyperglycemia and fluid shifts. Dose adjustments may be necessary in women with gestational diabetes or impaired glucose tolerance; consider using lower dextrose concentrations or adjusting infusion rate to maintain euglycemia. Plasma volume expansion in pregnancy requires careful monitoring to avoid fluid overload. No routine dose adjustment for lactated Ringer's components; however, adjust rate based on maternal fluid status, renal function, and electrolyte levels. In labor, avoid large volumes to prevent maternal hyponatremia or fetal fluid overload.
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.
Use as maintenance fluid in patients with ongoing losses (e.g., NPO status). Monitor serum glucose and electrolytes, especially in diabetic patients or those at risk for hyperglycemia. Avoid in patients with hyperkalemia due to potassium content. Not suitable for resuscitation due to hypotonicity. Use only if specific indication for dextrose exists (e.g., preventing ketosis).
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.
