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.
Intravenous dextrose provides a source of calories and water for hydration. Dextrose is metabolized to carbon dioxide and water, yielding energy (approximately 3.4 kcal/g). It also stimulates insulin secretion and promotes glycogen synthesis.

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.
Intravenous infusion, 500-1000 m L (50-100 g dextrose) as a single dose, rate determined by clinical condition; typical maintenance 100-125 m L/h.
Approximately 5-10 minutes for dextrose; lactated Ringer's components have variable half-lives: lactate 5-20 minutes, electrolytes follow renal clearance.
The metabolic half-life of glucose is 1.5–2.5 hours; however, the plasma half-life of infused dextrose is approximately 1.5–2 hours, with clinical context indicating that doses >0.5 g/kg/hour can exceed oxidative capacity, leading to hyperglycemia.
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.
Dextrose is metabolized via glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP, carbon dioxide, and water. Insulin facilitates cellular uptake and metabolism. Excess glucose is stored as glycogen in liver and muscle, or converted to fat via lipogenesis.
Renal: water and electrolytes are excreted renally; dextrose is metabolized to CO2 and water, with CO2 exhaled and water excreted renally. Biliary/fecal: negligible.
Glucose is primarily metabolized via glycolysis and oxidative phosphorylation to CO2 and water; less than 5% is excreted unchanged in urine under normal conditions. In hyperglycemia with glycosuria, up to 50% may be lost renally.
Dextrose: negligible; electrolytes: minimal binding; lactate: not significantly protein-bound.
Glucose is not significantly bound to plasma proteins (<10%); it is freely diffusible.
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.
Approximately 0.2 L/kg (total body water), reflecting distribution into extracellular and intracellular spaces; clinical meaning: Vd approximates total body water (0.6 L/kg in lean body mass), but glucose is rapidly taken up by cells.
Intravenous: 100% by definition.
Oral bioavailability is 100% for absorbed glucose; intravenous administration yields 100% bioavailability.
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 GFR-based dosing adjustment; contraindicated in anuria or oliguria due to volume overload risk; use with caution in renal impairment.
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.
No evidence for Child-Pugh-based adjustment; use with caution in severe hepatic impairment due to risk of fluid overload.
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.
Intravenous infusion, 5-10 mg/kg/min dextrose (equivalent to 3-6 m L/kg/h of D10W) for maintenance; adjust based on glucose monitoring.
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.
Caution due to risk of volume overload, heart failure, and electrolyte disturbances; start at lower rates and monitor closely.

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.
No direct food interactions. However, dietary intake of carbohydrates may need adjustment to prevent hyperglycemia. Monitor blood glucose levels if eating.
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.
No evidence of teratogenic effects in animal studies; not associated with congenital anomalies in humans regardless of trimester. Intravenous glucose crosses the placenta; maternal hyperglycemia may cause fetal hyperinsulinism and neonatal hypoglycemia. Use only if clearly needed.
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.
Endogenous glucose is a normal component of breast milk. Intravenous dextrose infusion increases maternal blood glucose, leading to increased milk glucose concentrations. No adverse effects expected. M/P ratio not applicable.
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.
Increased plasma volume in pregnancy may require higher initial doses to achieve euglycemia. No standard dose adjustment; titrate based on maternal blood glucose monitoring.
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.
Dextrose 10% in water (D10W) is a hypertonic solution (510 m Osm/L) that provides 340 kcal/L. Administer via central line to avoid phlebitis. Monitor serum glucose closely, especially in diabetics and critically ill patients. Use with caution in patients with intracranial hemorrhage as hyperglycemia may worsen outcomes. D10W is often used for neonatal hypoglycemia or as a maintenance fluid when higher dextrose concentrations are needed. Rapid infusion can cause hyperglycemia and osmotic diuresis.
