Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Plasma-Lyte M and Dextrose 5% is an intravenous solution that provides electrolytes and calories. Dextrose is a monosaccharide that serves as a source of calories and water for cellular metabolism. Electrolytes (sodium, potassium, magnesium, chloride, acetate, gluconate) maintain fluid and electrolyte balance, and acetate and gluconate act as bicarbonate precursors to correct acidosis.
Acetated Ringer's solution provides isotonic crystalloid fluid and electrolytes, with acetate as a bicarbonate precursor metabolized in the liver and peripheral tissues, buffering metabolic acidosis. It restores intravascular volume and corrects electrolyte imbalances.

Intravenous infusion; adult dose determined by fluid and electrolyte needs; typical maintenance: 100-200 m L/hour (2-3 L/day) for normovolemic patients; adjust based on serum electrolytes, glucose, and clinical status.
Intravenous infusion; dosing based on patient's fluid and electrolyte needs. Typical adult dose: 500-1000 m L per hour as needed for volume replacement; adjust rate based on clinical response and serum electrolyte monitoring.
Dextrose: <15 minutes (rapidly cleared from plasma); Electrolytes: No true half-life, as they are distributed and excreted according to homeostatic mechanisms.
Not applicable as a fixed half-life; components distribute and equilibrate rapidly. For administered volume, intravascular half-life is 20-30 minutes due to redistribution to interstitial space. Electrolyte half-lives: sodium ~8-12 hours, chloride ~8-12 hours, potassium ~12-24 hours, calcium ~24-48 hours, magnesium ~24-48 hours.
Dextrose is metabolized via glycolysis and the citric acid cycle to carbon dioxide and water, providing energy. Acetate and gluconate are metabolized primarily in the liver and skeletal muscle to bicarbonate. Electrolytes are not metabolized.
Acetate is metabolized via acetyl-Co A in the tricarboxylic acid cycle, yielding bicarbonate; primary sites include liver and skeletal muscle.
Renal: 90% (as water and electrolytes); Dextrose is metabolized to CO2 and water, with negligible renal excretion of unchanged drug.
Acetated Ringer's solution components are excreted primarily renally: water (100% via kidneys), sodium (90-95% renal, 5-10% sweat/feces), chloride (90-95% renal), acetate (metabolized to bicarbonate, then CO2 excreted via lungs; <5% renal), potassium (80-90% renal, 10-20% feces), calcium (98% renal reabsorption, <2% fecal), magnesium (70% renal, 30% fecal).
Minimal (<5%) for electrolytes and dextrose; not significantly bound to plasma proteins.
Calcium: ~40% bound to albumin; magnesium: ~30% bound to albumin; other components (sodium, potassium, chloride, acetate) have negligible protein binding (<5%).
Electrolytes: Vd of sodium ~0.6 L/kg (total body water); Dextrose: Vd ~0.2-0.3 L/kg (extracellular fluid); overall Vd approximates 0.6 L/kg.
Not a single value for all components. Water distributes into total body water (0.6 L/kg), sodium and chloride primarily into extracellular fluid (0.2 L/kg), potassium into intracellular fluid (0.4 L/kg), calcium and magnesium into bone and cells (Vd ~0.5-0.8 L/kg).
Not applicable; drug is only administered intravenously (IV), so bioavailability is 100%.
Intravenous: 100% (only route administered). Oral: not applicable; not administered orally.
Contraindicated in severe renal impairment (e GFR < 30 m L/min/1.73 m²) due to risk of potassium and magnesium accumulation; for e GFR 30-59 m L/min/1.73 m², reduce infusion rate by 50% and monitor electrolytes; no adjustment for e GFR ≥ 60 m L/min/1.73 m².
No specific GFR-based dose adjustment required; however, use with caution in renal impairment due to risk of fluid overload and electrolyte imbalances. Monitor serum potassium and renal function.
Child-Pugh Class A or B: no adjustment needed; Child-Pugh Class C: monitor serum magnesium and potassium closely due to reduced clearance; consider reduced infusion rate (e.g., 75% of normal) and frequent electrolyte monitoring.
No specific Child-Pugh dose adjustment; use with caution in severe hepatic impairment due to potential altered lactate metabolism. Monitor electrolytes and acid-base status.
Intravenous infusion; dose based on weight: infants: 100-150 m L/kg/day; children: 100-200 m L/kg/day; adjust for ongoing losses and serum glucose; not recommended for neonates due to risk of hyperkalemia; maximum infusion rate 2-5 m L/kg/hour depending on age and clinical status.
Weight-based dosing: 20-30 m L/kg as a bolus over 30-60 minutes for volume expansion; maintenance: adjust based on fluid deficit and ongoing losses. Maximum rate and volume vary by clinical condition.
Elderly patients: use lower initial rates (e.g., 50-100 m L/hour) with careful monitoring of fluid overload, serum electrolytes, and glucose tolerance; due to age-related renal decline, consider dose reduction if e GFR < 60 m L/min/1.73 m²; avoid in patients with heart failure or significant renal impairment.
Consider reduced initial volume and slower infusion rate due to decreased cardiovascular reserve and higher risk of fluid overload. Monitor closely for signs of heart failure and electrolyte disturbances.
Not for use in patients with intracranial or intraspinal hemorrhage, or in patients with known hypersensitivity to any component.
Not available; no FDA boxed warning.
Use with caution in patients with heart failure, renal impairment, or conditions predisposing to fluid overload.,Monitor serum glucose, electrolytes, and fluid status regularly.,Avoid rapid infusion to prevent hyperglycemia and osmotic diuresis.,Do not administer simultaneously with blood through the same infusion set (risk of hemolysis) unless using a Y-type connector with proper flushing.

No specific food interactions. Dietary potassium/magnesium intake should be monitored in patients receiving this solution to avoid electrolyte imbalance. Patients with diabetes should coordinate dextrose infusion with insulin and meal timing.
No specific food interactions. However, dietary intake of sodium and potassium should be considered in patients with electrolyte imbalances or renal impairment.
No evidence of teratogenicity. Plasma-Lyte M and Dextrose 5% is an isotonic crystalloid solution; dextrose and electrolytes are normal physiological constituents. Fetal risk is negligible as the solution is designed to replace fluids and electrolytes. No teratogenic effects reported in animal studies or human data. Trimester-independent low risk, but use only if clearly needed.
No fetal risks identified; acetated Ringer's solution is isotonic and used for fluid and electrolyte replenishment. No teratogenic effects reported in any trimester.
Compatible with breastfeeding. Components (dextrose, electrolytes) are endogenous and present in breast milk. No known M/P ratio available as the solution is composed of substances normally present in milk. Excretion is not clinically relevant; no adverse effects expected.
Considered safe during breastfeeding; components (sodium, chloride, potassium, calcium, acetate) are normal physiological constituents. M/P ratio not applicable.
No specific dose adjustments required. Pregnancy induces increased plasma volume (40-50%) and glomerular filtration rate (50-85%), but crystalloid solutions like Plasma-Lyte M and Dextrose 5% are dosed based on clinical need (fluid replacement, maintenance). Monitor for hyperglycemia due to dextrose; consider lower infusion rates in gestational diabetes or preeclampsia-related fluid sensitivity.
No dose adjustments required due to pregnancy; pharmacokinetics of electrolytes and water unchanged; adjust dosing based on clinical status and losses.
PLASMA-LYTE M AND DEXTROSE 5% is a balanced isotonic crystalloid containing multiple electrolytes (Na 40, K 13, Mg 3, Cl 40, acetate 16, gluconate 20 m Eq/L) with 5% dextrose. It is used for maintenance fluid therapy, particularly in pediatric or geriatric patients, or when mild potassium/magnesium supplementation is needed. The dextrose provides ~170 kcal/L and helps prevent ketosis. Avoid in patients with hyperkalemia, hypermagnesemia, or anuria. Acetate and gluconate serve as bicarbonate precursors (acetate is rapidly metabolized; gluconate slower). Monitor serum glucose in diabetics or stress states. Compatible with most IV medications; check specific compatibility.
Acetated Ringer's is an isotonic crystalloid containing acetate as a bicarbonate precursor; it does not require hepatic metabolism for alkalinization, unlike lactate, making it preferable in patients with hepatic impairment or lactic acidosis. Monitor serum electrolytes and acid-base status during infusion, especially in renal impairment. Do not administer through same IV line with blood products due to risk of hemolysis from calcium content. Avoid use in metabolic alkalosis.
