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.
Dextrose provides caloric support and increases serum glucose levels, while lactated Ringer's solution restores fluid and electrolyte balance. Lactate is metabolized to bicarbonate, buffering acidosis.
FDA-approved: Peripheral parenteral nutrition supplementation in patients who require caloric intake but cannot take adequate oral nutrition,Off-label: Treatment of hypoglycemia, as a component of total parenteral nutrition
Fluid and electrolyte replacement,Caloric supply,Treatment or prevention of dehydration,Metabolic acidosis correction (via lactate buffering)
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.
Intravenous infusion. Dose depends on patient's fluid and electrolyte needs. Typical adult infusion rate: 100-200 m L/hour. Maximum rate of dextrose infusion: 0.5 g/kg/hour to avoid hyperglycemia.
30-60 minutes for blood glucose to return to baseline after infusion cessation; clinical context: rapid metabolism via glycolysis.
Approximately 5-10 minutes for dextrose; lactated Ringer's components have variable half-lives: lactate 5-20 minutes, electrolytes follow renal clearance.
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.
Dextrose undergoes glycolysis and oxidative phosphorylation. Lactate is converted to pyruvate via lactate dehydrogenase (LDH) and then enters the citric acid cycle, primarily in the liver.
Renal: 100% as CO2 and water; no unchanged dextrose excreted in urine under normal conditions.
Renal: water and electrolytes are excreted renally; dextrose is metabolized to CO2 and water, with CO2 exhaled and water excreted renally. Biliary/fecal: negligible.
None (0%); dextrose does not bind to plasma proteins.
Dextrose: negligible; electrolytes: minimal binding; lactate: not significantly protein-bound.
0.15-0.25 L/kg; approximates extracellular fluid volume.
0.2-0.3 L/kg for dextrose (total body water); electrolytes distribute according to body water compartments (Na+ primarily extracellular, K+ intracellular), lactate distributes in total body water.
Oral: 100% (dextrose is completely absorbed).
Intravenous: 100% by definition.
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.
GFR < 50 m L/min: Monitor for fluid overload and electrolyte disturbances. Dose reduction may be necessary to avoid hyperkalemia due to potassium content (approximately 20 m Eq/L). GFR < 30 m L/min: Use with caution; consider alternative fluids. Anuria: Contraindicated.
No specific dose adjustment for Child-Pugh class; monitor serum glucose closely in patients with hepatic impairment due to altered glucose metabolism.
Child-Pugh Class B or C: Caution due to impaired lactate metabolism. Monitor lactate levels. May require alternative fluids in severe hepatic impairment to avoid lactic acidosis.
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.
Intravenous infusion. Dose based on weight and clinical condition. Typical maintenance: 100 m L/kg/day for first 10 kg, 50 m L/kg/day for next 10 kg, 20 m L/kg/day for each kg over 20 kg. Dextrose infusion rate should not exceed 0.5 g/kg/hour.
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.
Start at lower infusion rates (e.g., 50-100 m L/hour) due to decreased renal function and increased risk of fluid overload. Monitor electrolytes and glucose closely. Adjust rate based on volume status and comorbidities.
No black box warning.
None.
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
Use with caution in patients with congestive heart failure, renal impairment, or conditions causing fluid overload,Monitor serum glucose, especially in diabetics or patients with glucose intolerance,Risk of electrolyte imbalances,Not for use in patients with lactic acidosis or severe hepatic impairment,Avoid in patients with known hypersensitivity to corn-derived products
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)
Hyperglycemia or hyperlactatemia,Patients with severe metabolic acidosis (except when caused by dehydration),Severe renal failure (oliguria or anuria),Addison's disease,Administration of blood products through same IV line (due to risk of precipitation)
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.
No significant food interactions, as this is an intravenous solution. However, oral intake of high-potassium foods (bananas, oranges, spinach, potatoes) should be monitored in patients with hyperkalemia or renal impairment due to the potassium content of LR.
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.
No evidence of teratogenicity. Dextrose and lactated Ringer's are physiologic solutions; at therapeutic doses, no increased risk of fetal malformations in any trimester. However, electrolyte imbalances or hyperglycemia from misuse may pose indirect fetal risks.
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.
Excreted in breast milk in negligible amounts. Dextrose and electrolytes are normal milk constituents. No adverse effects expected. M/P ratio not determined as it is not pharmacologically active.
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.
No standard dose adjustment required. Use with caution in preeclampsia or gestational hypertension due to sodium load. Monitor for hyperglycemia in gestational diabetes; consider insulin if needed.
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.
D5LR is isotonic after infusion (osmolality ~525 m Osm/L initially, but rapidly equilibrates). Not for use in patients with lactic acidosis or known hyperlactatemia. Avoid in patients with galactosemia. Contains calcium; do not administer through same IV line as ceftriaxone (precipitation risk). Use with caution in renal impairment—risk of hyperkalemia from LR component. Blood transfusions via LR can cause citrate anticoagulant toxicity; prefer NS. In DKA, LR may worsen lactic acidosis—use NS initially. For hypovolemic patients, D5LR provides free water after dextrose metabolism; monitor for hyperglycemia.
