Expansol Injection 6%+0.9% is an intravenous solution containing Hydroxyethyl Starch (HES) 6% and Sodium Chloride 0.9%, designed for plasma volume expansion in patients experiencing hypovolemia. Hypovolemia, a condition of decreased blood volume, may result from trauma, surgery, burns, or severe fluid loss. Expansol works by restoring circulatory volume, improving tissue perfusion, and supporting hemodynamic stability.

Hydroxyethyl Starch, a synthetic colloid, is a macromolecular substance that remains in the vascular compartment longer than crystalloids, providing sustained plasma volume expansion. Sodium chloride (normal saline) balances electrolytes and ensures isotonicity with blood plasma.

Indications

Expansol Injection 6%+0.9% is indicated for:

• Acute hypovolemia caused by hemorrhage, trauma, or surgery

• Shock associated with fluid loss

• Burns where plasma volume expansion is necessary

• Prevention of hypotension during major surgical procedures

• Adjunctive fluid therapy when crystalloids alone are insufficient to restore intravascular volume

Dosage and Administration

Adult Dosage:

• Initial dose: 500–1000 ml intravenously, administered slowly, depending on the patient’s condition and clinical response

• Maintenance infusion: Adjusted according to hemodynamic parameters, ongoing blood loss, and patient tolerance

• Maximum daily dose of HES: 20–25 ml/kg body weight for critically ill patients, and up to 50 ml/kg in perioperative patients

Administration Guidelines:

• Administer via a sterile intravenous infusion set under aseptic conditions

• Use a central or peripheral vein depending on infusion rate and patient condition

• Monitor blood pressure, heart rate, and urine output to assess the effectiveness of therapy

• Avoid rapid administration in patients at risk of fluid overload, such as those with cardiac or renal insufficiency

• Do not mix with other medications in the same infusion line unless compatibility is confirmed

Mechanism of Action

Hydroxyethyl Starch in Expansol increases the colloid osmotic pressure in the plasma, drawing water from the interstitial space into the intravascular compartment. This restores circulating blood volume, improves cardiac output, and maintains adequate tissue perfusion. Sodium chloride provides isotonicity and prevents electrolyte imbalance during fluid replacement therapy.

Contraindications

Expansol Injection should not be used in patients with:

• Severe renal impairment or oliguria

• Uncontrolled bleeding due to coagulation disorders

• Hypersensitivity to hydroxyethyl starch or any component of the formulation

• Severe heart failure or pulmonary edema where fluid overload is a risk

Side Effects

Possible adverse reactions may include:

• Mild allergic reactions (rash, itching, or urticaria)

• Fluid overload leading to pulmonary edema in susceptible patients

• Temporary increase in blood pressure

• Rare: coagulopathy with prolonged or high-dose use

• Local reactions at the infusion site such as redness or pain

Precautions and Warnings

• Monitor renal function during therapy, especially in critically ill patients

• Use cautiously in elderly patients or those with cardiovascular compromise

• Avoid exceeding recommended dosage to prevent coagulation disturbances or volume overload

• Stop infusion immediately if signs of allergic reaction or pulmonary edema appear

Pregnancy and Lactation

• Safety in pregnancy and lactation has not been firmly established. Use only if clearly indicated and with close monitoring.

Storage Conditions

• Store at 20–25°C, protected from light

• Do not freeze

• Keep the solution in its original container until use

• Keep out of reach of children

Summary

Expansol Injection 6%+0.9% (Hydroxyethyl Starch + Sodium Chloride) is a safe and effective plasma volume expander used to treat hypovolemia, shock, burns, and surgical fluid loss. Its colloidal properties ensure prolonged intravascular retention, while sodium chloride maintains electrolyte balance. Proper administration, monitoring, and adherence to dosage recommendations are essential for optimal outcomes.
