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 is a monosaccharide that serves as a source of calories and water for hydration. It is metabolized to carbon dioxide and water, yielding energy. Ringer's solution provides electrolytes (sodium, chloride, potassium, calcium) to maintain fluid and electrolyte balance.
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
Intravenous infusion for restoration of fluid and electrolyte balance,Source of calories (dextrose) in parenteral nutrition,Treatment of dehydration,Vehicle for drug administration
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; dosing based on glucose requirements and fluid status. Typical adult dose: 500-1000 m L at 1-2 m L/min. Not to exceed 0.5 g/kg/h glucose.
30-60 minutes for blood glucose to return to baseline after infusion cessation; clinical context: rapid metabolism via glycolysis.
Dextrose: not applicable as it is rapidly metabolized; exogenous dextrose has an elimination half-life of approximately 0.5-1 hour due to insulin-mediated uptake and metabolism. Electrolytes: no relevant half-life.
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 is metabolized via glycolysis and the citric acid cycle to carbon dioxide and water, yielding energy. Metabolism is insulin-dependent; in the presence of insulin, it is taken up by cells and phosphorylated to glucose-6-phosphate.
Renal: 100% as CO2 and water; no unchanged dextrose excreted in urine under normal conditions.
Renal: dextrose is completely metabolized; no significant renal excretion of intact dextrose. Ringer's solution components (Na+, K+, Ca2+, Cl-) are primarily excreted renally, with >90% of infused ions eliminated unchanged in urine.
None (0%); dextrose does not bind to plasma proteins.
Dextrose: negligible (<5%, not bound to proteins). Electrolytes: minimal protein binding (Na+, K+, Ca2+: <10% bound primarily to albumin for calcium).
0.15-0.25 L/kg; approximates extracellular fluid volume.
Dextrose: ~0.5 L/kg (total body water). Electrolytes: distribute into extracellular fluid (~0.2 L/kg).
Oral: 100% (dextrose is completely absorbed).
Intravenous: 100%.
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 specific dose adjustment. Use with caution in renal impairment due to potential fluid overload; monitor electrolytes and glucose.
No specific dose adjustment for Child-Pugh class; monitor serum glucose closely in patients with hepatic impairment due to altered glucose metabolism.
No specific dose adjustment. Monitor glucose closely in severe hepatic impairment due to altered gluconeogenesis.
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; initial rate 5-10 m L/kg, then titrate. Maximum glucose infusion rate: 0.2-0.3 g/kg/h for term infants.
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.
Use lower initial infusion rates (0.5-1 m L/min) and monitor for fluid overload and hyperglycemia due to decreased renal function and glucose tolerance.
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 hyperglycemia, diabetes mellitus, or glucose intolerance,Monitor serum electrolytes, fluid balance, and blood glucose levels,Risk of fluid overload in patients with cardiac or renal impairment,May cause hyperglycemia, hyperosmolality, and osmotic diuresis,Not for use in patients with intracranial hemorrhage or hepatic coma
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)
Hypersensitivity to any component,Hyperglycemia with severe dehydration,Intracranial hemorrhage,Hepatic coma,Severe renal impairment with oliguria or anuria
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 specific food interactions. However, monitor glucose intake in diabetic patients. Avoid concurrent administration with blood products.
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.
Dextrose 5% in Ringer's solution is not teratogenic. Dextrose is a physiologic sugar; Ringer's solution contains electrolytes at concentrations similar to plasma. No fetal risks are reported from IV administration at standard doses. Excessive dextrose may cause maternal hyperglycemia, which can lead to fetal macrosomia and neonatal hypoglycemia, but this is not teratogenic.
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.
Dextrose and electrolytes are normal components of breast milk. IV infusion does not pose risk to nursing infant. M/P ratio not applicable as dextrose is endogenous.
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 dose adjustment required. However, in preeclampsia or gestational hypertension, monitor for fluid overload; reduce infusion rate if needed. In gestational diabetes, adjust dextrose concentration or use alternative fluids to maintain euglycemia.
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.
This solution provides 170 calories per liter from dextrose. Use within 24 hours of spiking the IV set. Do not administer simultaneously with blood products through the same line due to risk of hemolysis and aggregation. Monitor serum glucose in diabetic patients.
This solution contains sugar (dextrose) and will be given through a central intravenous line.,Report any signs of infection at the catheter site, such as redness, swelling, or pain.,Notify your healthcare provider if you experience headaches, confusion, or frequent urination, which could indicate high blood sugar.,Do not adjust the infusion rate; it is precisely controlled to avoid complications.
This IV solution provides fluids and sugar to help maintain your body's energy levels.,Report any signs of allergic reaction, such as rash, itching, or difficulty breathing.,Inform your healthcare provider if you have diabetes, kidney problems, or heart failure.,The solution may cause temporary increase in blood sugar levels.
