Natriumchloride Fresenius Kabi (Sodium Chloride)

Sodium Chloride is used in the management of fluid and electrolyte disorders.

• Fluid replacement: restores intravascular volume in patients with dehydration or blood loss.
• Electrolyte replenishment: corrects sodium and chloride deficits during surgery or illness.
• Hypovolemia: supports circulatory volume in conditions such as trauma, burns, or severe diarrhea.

• Sodium Chloride provides Na+ and Cl- ions that increase extracellular osmolarity, drawing water into the vascular compartment. This raises plasma volume, corrects electrolyte imbalances, and helps maintain osmotic pressure, thereby supporting circulatory stability and tissue perfusion.

Sodium Chloride administered intravenously may be associated with several adverse reactions.

Common Side Effects

• Injection site pain: discomfort at the infusion site.
• Phlebitis: inflammation of the vein used for infusion.
• Hypernatremia: elevated serum sodium levels.
• Hyperchloremia: elevated serum chloride levels.
• Fluid overload: excess extracellular fluid accumulation.
• Electrolyte imbalance: transient shifts in other electrolytes.

Serious or Rare Side Effects

• Severe hypernatremia: can lead to neurological symptoms.
• Pulmonary edema: fluid accumulation in the lungs.
• Anaphylactic reaction: rare severe allergic response.
• Metabolic acidosis: due to excess chloride.
• Cardiac arrhythmia: secondary to electrolyte disturbances.
• Hyperchloremic metabolic acidosis: rare but serious acid‑base disturbance.

When using intravenous sodium chloride, careful clinical assessment is essential to minimise risks.

• Assess fluid status: avoid over‑infusion in patients with heart failure or renal impairment.
• Monitor electrolytes: check serum Na+ and Cl- regularly during therapy.
• Use caution in renal impairment: adjust volume and rate according to kidney function.
• Avoid rapid infusion: infuse over the recommended time to prevent circulatory overload.
• Pregnancy and lactation: use only if clearly needed after risk‑benefit evaluation.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Sodium chloride can interact with other agents that affect fluid and electrolyte balance.

Major Interactions (Avoid)

• Concurrent hypertonic saline: risk of severe hypernatremia.
• Loop diuretics: may exacerbate electrolyte shifts and volume depletion.
• ACE inhibitors/ARBs combined with potassium supplements: increased risk of electrolyte disturbances.

Moderate Interactions (Monitor Closely)

• Colloids (e.g., albumin): may alter overall fluid balance.
• Blood products: monitor for changes in serum electrolytes.
• Corticosteroids: can increase sodium retention and affect volume status.
• Other IV fluids: ensure compatible electrolyte composition to avoid overload.
• Anticoagulants: monitor for bleeding if large volumes are infused rapidly.
