0.9% w/v SODIUM CHLORIDE INFUSION [PSI] Infusion/Solution for

What is 0.9% w/v SODIUM CHLORIDE INFUSION [PSI]

0.9% w/v Sodium Chloride Infusion [PSI] is a sterile, isotonic intravenous solution containing sodium chloride as its active ingredient. Packaged in a 100ml NON-PVC bag, this infusion is commonly referred to as “normal saline” and is widely used in clinical settings for a variety of purposes. It plays a crucial role in restoring fluid and electrolyte balance in the body, particularly in cases of dehydration, shock, or surgery.

• Composition: Each 100 ml of solution contains 0.9 grams of sodium chloride.
• Form: Clear, colorless solution for infusion.
• Route of Administration: Intravenous (IV) only.
• Classification: Electrolyte replenishment therapy / Parenteral fluid therapy.

It is frequently used as a vehicle for the administration of other IV medications, or as a stand-alone fluid replacement in patients with low blood volume (hypovolemia). This product is free from PVC, reducing the risk of leachables and plasticizers that may pose health concerns in vulnerable patients such as neonates or individuals undergoing long-term infusion therapy.

0.9% Sodium Chloride Infusion [PSI] is considered one of the safest and most versatile IV solutions in clinical practice. It mimics the osmolarity of human plasma, making it ideal for volume expansion without altering serum sodium concentration when used correctly.

How to use 0.9% w/v SODIUM CHLORIDE INFUSION [PSI]

Administering 0.9% w/v Sodium Chloride Infusion [PSI] must be done under the supervision of a healthcare professional. It is primarily given intravenously through a sterile technique to ensure safety and effectiveness.

• Administration Route: Intravenous infusion via a sterile IV line.
• Preparation: No dilution is required. The solution is ready to use directly from the 100ml NON-PVC bag.
• Monitoring: Patients should be closely monitored for fluid balance, electrolyte levels, and signs of fluid overload or sodium imbalance.
• Equipment: Use an infusion set with aseptic precautions. An infusion pump may be used for precise administration.

The rate and volume of administration depend on the patient's clinical condition, age, weight, and ongoing fluid losses. For general hydration purposes or as a carrier fluid, a slow, continuous infusion may be employed. In emergency settings like hypovolemic shock, a faster infusion rate may be necessary.

Always inspect the solution visually before administration. If you observe any particulates, discoloration, or damage to the NON-PVC bag, discard the product. Once opened, the solution should be used immediately and not stored for later use to avoid contamination risks.

This product should never be injected intramuscularly or subcutaneously. Reuse or repurposing of partially used bags is strictly discouraged due to contamination risks.

Mode of Action 0.9% w/v SODIUM CHLORIDE INFUSION [PSI]

The therapeutic effects of 0.9% w/v Sodium Chloride Infusion [PSI] stem from its ability to restore extracellular fluid volume and correct electrolyte imbalances. As an isotonic solution, it contains the same osmotic pressure as blood plasma, allowing it to distribute primarily within the extracellular compartment without causing significant fluid shifts between compartments.

• Primary Action: Replaces lost fluid and sodium in conditions such as dehydration, hypovolemia, or electrolyte disturbances.
• Plasma Volume Expander: Helps maintain adequate circulatory volume and blood pressure in cases of acute fluid loss.
• Electrolyte Balancer: Restores sodium and chloride ions, which are critical for nerve conduction, muscle contraction, and acid-base balance.

Sodium ions play a vital role in maintaining osmotic equilibrium, while chloride ions aid in acid-base balance and hydrochloric acid production in the stomach. The infusion does not cross cell membranes freely, thus remains in the extracellular space (intravascular and interstitial), making it ideal for volume resuscitation.

By matching the body’s natural osmolarity, the solution avoids causing hemolysis or cellular dehydration, making it particularly safe in most patients when administered appropriately. It serves as a cornerstone in emergency care, perioperative management, and general supportive therapy.

0.9% w/v SODIUM CHLORIDE INFUSION [PSI] Interactions 0.9% w/v SODIUM CHLORIDE INFUSION [PSI]

Though 0.9% Sodium Chloride Infusion [PSI] is generally safe and well-tolerated, it can interact with certain medications and clinical conditions, especially when administered in large volumes or over prolonged periods.

• Diuretics: May exacerbate electrolyte loss when co-administered with loop or thiazide diuretics.
• Corticosteroids: Concurrent use may increase sodium and fluid retention, leading to edema or hypertension.
• Potassium supplements or potassium-sparing drugs: Require caution due to the risk of electrolyte imbalance or hyperkalemia in some patients.
• Calcium-containing solutions: Should be administered separately as calcium may precipitate with chloride under certain conditions.
• NSAIDs: May impair renal sodium excretion, increasing the risk of fluid overload and hypertension.

Additionally, interactions may occur if the infusion is used as a diluent for drugs that are unstable or incompatible with sodium chloride. Always consult compatibility charts or guidelines when using this infusion as a carrier for IV medications.

Patients with certain health conditions such as congestive heart failure, renal impairment, or hepatic cirrhosis may be more susceptible to fluid overload, so drug-fluid interactions must be considered holistically in these populations.

Dosage of 0.9% w/v SODIUM CHLORIDE INFUSION [PSI]

The dosage of 0.9% w/v Sodium Chloride Infusion [PSI] depends on the individual clinical situation, including the patient’s age, weight, underlying conditions, and therapeutic goals.

• Adults: Commonly used in volumes of 500ml to 1000ml per day for maintenance or replacement therapy. In emergencies, higher rates may be used.
• Children: Dosage typically calculated based on body weight (e.g., 20–60 ml/kg/day), and should be carefully monitored.
• Geriatric Patients: Require cautious administration due to higher risk of cardiac or renal complications.
• Rate of Infusion: Varies between slow infusion (e.g., 50–100 ml/hr) and rapid bolus (e.g., 250–500 ml over 30–60 min) based on clinical needs.

For medication dilution, the amount of sodium chloride used should be guided by the specific drug’s compatibility and concentration requirements. The infusion rate should always be adjusted based on serum sodium levels, urine output, blood pressure, and other clinical parameters.

It is vital to avoid excessive volumes that may lead to hypernatremia or fluid overload, especially in patients with cardiovascular or renal dysfunction.

Possible side effects of 0.9% w/v SODIUM CHLORIDE INFUSION [PSI]

Though generally safe and well-tolerated, 0.9% Sodium Chloride Infusion [PSI] may cause certain side effects, especially when used in large quantities or in susceptible patients.

• Common Side Effects:
• Local vein irritation or phlebitis at the infusion site
• Mild swelling or pain around the IV area
• Serious Side Effects:
• Fluid overload (hypervolemia) leading to pulmonary edema
• Hypernatremia (high sodium levels)
• Hypertension or exacerbation of heart failure
• Electrolyte imbalance
• Rare Side Effects:
• Allergic reactions (very uncommon)
• Metabolic acidosis (with excessive chloride levels)

Patients should be observed for signs of dyspnea, peripheral edema, confusion, or elevated blood pressure during infusion. Prompt adjustment of the infusion rate or discontinuation may be required in case of adverse effects.
