Natriumklorid B. Braun (Sodium Chloride)

• Sodium chloride injection is used to manage fluid and electrolyte disorders.
• Fluid replacement: provides isotonic fluid to maintain intravascular volume in patients with dehydration, blood loss or burns.
• Electrolyte imbalance correction: supplies sodium and chloride ions to normalize serum electrolyte concentrations in hyponatremic or hypochloremic states.
• Blood volume expansion: increases circulating blood volume during surgical procedures or trauma to support hemodynamic stability.

• Intravenous sodium chloride delivers sodium (Na⁺) and chloride (Cl⁻) ions directly into the bloodstream, increasing extracellular osmolarity and expanding plasma volume. The added ions draw water into the vascular compartment, restoring intravascular pressure and correcting hyponatremia or hypochloremia. By matching physiological concentrations, the solution maintains osmotic balance without causing significant shifts in intracellular fluid compartments.

Adverse reactions to sodium chloride injection are generally related to volume status and electrolyte shifts.

Common Side Effects

• Hypernatremia: elevated serum sodium levels causing thirst, confusion or weakness.
• Fluid overload: signs of edema, pulmonary congestion or increased blood pressure.
• Phlebitis: irritation or inflammation at the infusion site.
• Injection site pain: discomfort or burning sensation during administration.

Serious or Rare Side Effects

• Hyperchloremic metabolic acidosis: significant acid‑base disturbance requiring medical intervention.
• Pulmonary edema: severe fluid accumulation in the lungs leading to respiratory distress.
• Anaphylactoid reaction: rare hypersensitivity with rash, hypotension or bronchospasm.
• Cardiac overload: exacerbation of heart failure with arrhythmias or reduced cardiac output.

Before administering sodium chloride injection, consider the following precautions to ensure safe use.

• Assess fluid status: evaluate the patient’s volume status and cardiac function prior to infusion.
• Monitor electrolytes: regularly check serum sodium, chloride and overall electrolyte balance during therapy.
• Infuse at appropriate rate: avoid rapid administration to reduce risk of circulatory overload.
• Use caution in renal or cardiac failure: patients with compromised fluid excretion are at higher risk of edema.
• Pregnancy: limited safety data; administer only when clearly indicated and benefits outweigh risks.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Sodium chloride may interact with other medications that affect fluid balance or electrolyte concentrations.

Major Interactions (Avoid)

• Hypertonic saline solutions: concurrent use can cause severe hypernatremia.
• Loop diuretics: may exacerbate electrolyte disturbances when combined with large-volume saline.
• Potassium‑sparing agents (e.g., ACE inhibitors, ARBs) together with potassium supplements: increased risk of hyperkalemia.

Moderate Interactions (Monitor Closely)

• Corticosteroids: can enhance sodium retention, requiring electrolyte monitoring.
• Blood products (e.g., packed red cells): may alter chloride levels and affect acid‑base status.
• Antihypertensive agents: volume expansion may reduce efficacy, necessitating dose adjustment.
