PLASMA-LYTE M AND DEXTROSE 5% IN PLASTIC CONTAINER

PLASMA-LYTE M AND DEXTROSE 5% IN PLASTIC CONTAINER

Clinical safety rating

caution

Comprehensive clinical and safety monograph for PLASMA-LYTE M AND DEXTROSE 5% IN PLASTIC CONTAINER (PLASMA-LYTE M AND DEXTROSE 5% IN PLASTIC CONTAINER).


Mechanism of Action

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.

What the body does with it

MetabolismDextrose 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.
ExcretionRenal: 90% (as water and electrolytes); Dextrose is metabolized to CO2 and water, with negligible renal excretion of unchanged drug.
Half-lifeDextrose: <15 minutes (rapidly cleared from plasma); Electrolytes: No true half-life, as they are distributed and excreted according to homeostatic mechanisms.
Protein bindingMinimal (<5%) for electrolytes and dextrose; not significantly bound to plasma proteins.
Volume of DistributionElectrolytes: 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.
BioavailabilityNot applicable; drug is only administered intravenously (IV), so bioavailability is 100%.
Onset of ActionIntravenous: Immediate, with plasma volume expansion occurring within minutes; Dextrose infusion provides rapid glucose elevation (within 2-5 minutes) if hypoglycemic.
Duration of ActionIntravenous: 2-4 hours for volume effect, depending on fluid shifts; Glucose effect lasts as long as infusion continues, with return to baseline after cessation.

Classification & Brands

Dosing & administration

Intravenous infusion; adult dose determined by fluid and electrolyte needs; typical maintenance: 100-200 mL/hour (2-3 L/day) for normovolemic patients; adjust based on serum electrolytes, glucose, and clinical status.

Dosage formINJECTABLE
Renal impairmentContraindicated in severe renal impairment (eGFR < 30 mL/min/1.73 m²) due to risk of potassium and magnesium accumulation; for eGFR 30-59 mL/min/1.73 m², reduce infusion rate by 50% and monitor electrolytes; no adjustment for eGFR ≥ 60 mL/min/1.73 m².
Liver impairmentChild-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.
Pediatric useIntravenous infusion; dose based on weight: infants: 100-150 mL/kg/day; children: 100-200 mL/kg/day; adjust for ongoing losses and serum glucose; not recommended for neonates due to risk of hyperkalemia; maximum infusion rate 2-5 mL/kg/hour depending on age and clinical status.
Geriatric useElderly patients: use lower initial rates (e.g., 50-100 mL/hour) with careful monitoring of fluid overload, serum electrolytes, and glucose tolerance; due to age-related renal decline, consider dose reduction if eGFR < 60 mL/min/1.73 m²; avoid in patients with heart failure or significant renal impairment.

Use during pregnancy

1st trimesterGenerally considered safe; use only if clearly needed. No known teratogenic effects.
2nd trimesterGenerally considered safe; use only if clearly needed. Monitor fluid and electrolyte balance.
3rd trimesterUse with caution; may cause fluid overload or electrolyte disturbances in mother or fetus.

Clinical note

Comprehensive clinical and safety monograph for PLASMA-LYTE M AND DEXTROSE 5% IN PLASTIC CONTAINER (PLASMA-LYTE M AND DEXTROSE 5% IN PLASTIC CONTAINER).

Placental transferDextrose and electrolytes readily cross the placenta. No evidence of harm.
BreastfeedingDextrose and electrolytes are normal constituents of breast milk. No known adverse effects on infant when used as directed.
Lactation RatingSafe
Teratogenic RiskNo 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.
Fetal MonitoringMonitor maternal serum electrolytes, fluid balance, blood glucose (especially in gestational diabetes or impaired glucose tolerance), and signs of fluid overload (e.g., edema, pulmonary congestion). Fetal monitoring not routinely required unless maternal condition warrants (e.g., preeclampsia); assess fetal heart rate if maternal electrolyte disturbances or fluid overload occur.
Fertility EffectsNo known adverse effects on fertility. The solution contains normal physiological components; no reproductive toxicity or impact on spermatogenesis or oogenesis reported. Use in IVF protocols for fluid resuscitation without fertility impairment.

Warnings & precautions

■ FDA Black Box Warning

Not for use in patients with intracranial or intraspinal hemorrhage, or in patients with known hypersensitivity to any component.

Absolute Contraindications

HyperglycemiaHypersensitivity to any componentSevere electrolyte disorders (e.g., hyperkalemia, hypernatremia)Severe fluid overloadRenal failure with oliguria or anuria

Clinical Precautions

PrecautionsUse 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.
Food/DietaryNo 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.

Clinical Tips & Counseling

Clinical PearlsPLASMA-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 mEq/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.
Patient AdviceThis intravenous solution contains sugar (dextrose) and electrolytes to maintain fluid balance and provide calories. · Tell your healthcare provider if you have diabetes, kidney problems, or heart disease. · Report any signs of fluid overload: swelling, shortness of breath, or rapid weight gain. · This solution may be given with other medications; inform your nurse of all medications you are taking. · You may experience a cold sensation at the IV site; this is usually temporary.
