Natriumchloride Laboratoire Aguettant (Sodium Chloride)

Natriumchloride is an intravenous electrolyte solution used to manage disorders of fluid and electrolyte balance.

• Fluid replacement: restores intravascular volume in patients with acute fluid loss.
• Electrolyte balance: provides sodium and chloride ions to correct hyponatremia.
• Dehydration: rehydrates individuals unable to maintain adequate oral intake.
• Hyponatremia: raises serum sodium concentration in low‑sodium states.

• Sodium chloride delivers sodium (Na⁺) and chloride (Cl⁻) ions directly into the bloodstream, expanding the extracellular fluid compartment. The increased osmolarity draws water into the vascular space, raising plasma volume and normalising serum electrolyte concentrations. This osmotic shift supports tissue perfusion and stabilises cellular function in patients with fluid deficits or electrolyte disturbances.

Adverse reactions may occur with intravenous administration of sodium chloride solutions.

Common Side Effects

• Injection site pain: mild discomfort at the infusion site.
• Phlebitis: inflammation of the vein used for infusion.
• Mild hypernatremia: elevated serum sodium if administered excessively.
• Local hypersensitivity: rash or itching at the site.
• Fluid overload (mild): transient swelling in susceptible patients.

Serious or Rare Side Effects

• Severe hypernatremia: significant rise in serum sodium leading to neurological symptoms.
• Anaphylaxis: acute, life‑threatening allergic reaction.
• Cardiac arrhythmia: electrolyte imbalance affecting heart rhythm.
• Pulmonary edema: fluid accumulation in lungs due to overload.
• Severe hypersensitivity: systemic rash, fever, or organ involvement.

Before administering Natriumchloride, clinicians should evaluate patient status and monitor for potential complications.

• Assess fluid status: determine hydration level and volume needs.
• Monitor serum electrolytes: check sodium and chloride concentrations regularly.
• Evaluate cardiac function: watch for signs of arrhythmia in at‑risk patients.
• Adjust infusion rate: tailor speed to avoid rapid shifts in osmolarity.
• Use aseptic technique: prevent contamination during preparation and administration.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Sodium chloride may interact with other agents that influence fluid or electrolyte balance.

Major Interactions (Avoid)

• Concurrent hypertonic saline solutions: risk of severe hypernatremia.
• Loop diuretics: may exacerbate electrolyte shifts and volume depletion.
• Cardiac glycosides: electrolyte changes can alter drug activity and toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors: monitor blood pressure and renal function.
• NSAIDs: may affect renal handling of sodium and fluid balance.
