PLASMA-LYTE 56 IN PLASTIC CONTAINER

PLASMA-LYTE 56 IN PLASTIC CONTAINER

Clinical safety rating

caution

Comprehensive clinical and safety monograph for PLASMA-LYTE 56 IN PLASTIC CONTAINER (PLASMA-LYTE 56 IN PLASTIC CONTAINER).


Mechanism of Action

PLASMA-LYTE 56 is an isotonic crystalloid solution that provides electrolytes and water to maintain or restore intravascular volume and electrolyte balance. It expands extracellular fluid volume and improves circulation by increasing plasma volume. The solution's electrolyte composition mimics plasma, helping to correct electrolyte deficits and acid-base disturbances.

What the body does with it

MetabolismPLASMA-LYTE 56 is a crystalloid solution; its components are not metabolized. Electrolytes are distributed and eliminated via renal excretion and normal physiological pathways. The solution itself is not subject to hepatic metabolism.
ExcretionPrimarily renal; >90% of infused electrolytes are excreted unchanged in urine; fecal elimination negligible (<5%).
Half-lifeNot applicable as a fixed value; infused electrolytes distribute and are eliminated according to individual ion kinetics (e.g., sodium t½ ~30 min, chloride t½ ~1–2 h) with rapid redistribution.
Protein bindingMinimal (<5%); electrolytes (Na+, Cl-, K+, Mg2+, acetate, gluconate) are not significantly protein-bound.
Volume of DistributionApproximately 0.2–0.3 L/kg for sodium and chloride, corresponding to extracellular fluid volume; distributed throughout ECF.
Bioavailability100% by intravenous route; not administered orally (bioavailability not applicable).
Onset of ActionImmediate; intravenous infusion achieves plasma volume expansion and electrolyte correction within minutes.
Duration of ActionShort; effects on volume and electrolytes persist for 2–4 hours post-infusion, depending on renal function and ongoing losses.
Molecular WeightNot applicable (multiple components: sodium 56 mEq/L, chloride 56 mEq/L, etc.; no single molecular weight).

Classification & Brands

Dosing & administration

Intravenous infusion; dose depends on fluid and electrolyte needs; typical adult rate: 100-200 mL/hour.

Dosage formINJECTABLE
Renal impairmentContraindicated in severe renal impairment (GFR <30 mL/min) due to risk of potassium and magnesium accumulation; use with caution and monitor electrolytes in moderate impairment (GFR 30-59 mL/min).
Liver impairmentNo specific adjustment required; however, monitor electrolytes in severe hepatic impairment due to risk of fluid overload and electrolyte imbalances.
Pediatric useDose based on weight and clinical status; typical initial infusion rate: 5-10 mL/kg/hour, adjusted based on response and electrolyte monitoring.
Geriatric useUse with caution due to reduced renal function; start at lower infusion rates (e.g., 50-100 mL/hour) and monitor for fluid overload and electrolyte disturbances.

Use during pregnancy

1st trimesterPLASMA-LYTE 56 is a balanced electrolyte solution used for intravenous fluid and electrolyte replacement. No teratogenic effects reported in animal studies; however, insufficient human data. Use only if clearly needed and benefit outweighs risk.
2nd trimesterSimilar to T1; monitor maternal and fetal electrolytes and fluid balance. No known fetal harm but limited data.
3rd trimesterUse with caution due to potential for fluid overload and electrolyte disturbances affecting maternal and fetal status. Monitor closely during labor and delivery.

Clinical note

Comprehensive clinical and safety monograph for PLASMA-LYTE 56 IN PLASTIC CONTAINER (PLASMA-LYTE 56 IN PLASTIC CONTAINER).

Placental transferElectrolytes and water from PLASMA-LYTE 56 readily cross the placenta; no specific data on the solution itself but components cross freely.
BreastfeedingExcreted into breast milk in small amounts; considered compatible with breastfeeding when used as indicated. Monitor infant for electrolyte imbalances if high doses are used.
Lactation RatingL2 (Probably Compatible)
Teratogenic RiskNo known teratogenic effects. Plasma-Lyte 56 is an electrolyte solution and does not cross placenta in significant amounts to cause fetal harm. Use if clearly needed.
Fetal MonitoringMonitor maternal serum electrolytes, fluid balance, and renal function during prolonged infusion. Fetal heart rate monitoring only if maternal condition warrants.
Fertility EffectsNo known effects on fertility. Normal electrolyte balance is required for reproductive function.

Side Effect Profile

Serious Effects

Absolute Contraindications

HypervolemiaHypersensitivity to any componentSevere electrolyte imbalance (unless corrected first)Severe renal impairment (oliguria, anuria)

Clinical Precautions

PrecautionsUse with caution in patients with heart failure, renal impairment, or conditions predisposing to fluid overload (e.g., congestive heart failure, pulmonary edema), Monitor electrolytes, fluid balance, and renal function during administration, Avoid in patients with hypervolemia, since this may exacerbate fluid overload conditions, Use with caution in patients receiving corticosteroids or corticotropin, as they may increase risk of fluid and electrolyte disturbances, Solutions containing acetate should be used with caution in patients with hepatic insufficiency
Food/DietaryNo specific food interactions; maintain normal diet unless otherwise directed by physician. Avoid excessive potassium-rich foods if renal impairment exists.

Clinical Tips & Counseling

Clinical PearlsPlasma-Lyte 56 is a balanced crystalloid solution containing acetate and gluconate as buffers, which may reduce the risk of hyperchloremic metabolic acidosis compared to 0.9% saline. It is isotonic (osmolarity 406 mOsm/L) but hypotonic in plasma due to metabolism of anions, making it suitable for maintenance fluid therapy. Use caution in patients with renal impairment due to potassium content (13 mEq/L). Not for co-administration with blood products via same tubing due to calcium content (5 mEq/L).
Patient AdviceThis solution provides fluids and electrolytes to maintain hydration and balance. · It contains potassium; follow dietary restrictions if you have kidney problems. · Report any signs of fluid overload (swelling, shortness of breath) or electrolyte imbalances (muscle cramps, weakness, irregular heartbeat). · Do not eat or drink anything unless instructed by your healthcare provider during infusion.
