Dextran 70 IV Infusion

This is indicated in aid in Hysteroscopy, Thromboembolic disorders, Prophylaxis of pulmonary embolism or venous thrombosis in moderate- to high-risk patients undergoing surgery, Prophylaxis of postoperative thromboembolic disorders, Hypovolaemic shock.

Dextran produce expansion of plasma volume. It also reduces blood viscosity and inhibits sludging or aggregation of red blood cells.

Sodium chloride is the major extracellular cation. It is important in electrolyte and fluid balance, osmotic pressure control and water distribution as it restores sodium ions. It is used as a source of electrolytes and water for hydration, treatment of metabolic acidosis, priming solution in haemodialysis and treatment of hyperosmolar diabetes. It is also used as diluents for infusion of compatible drug additives.

Dextran: Enzyme inducers e.g. phenytoin or carbamazepine and enzyme inhibitors e.g. cimetidine.

Sodium Chloride: May affect serum concentrations of lithium.

Hypersensitivity. Severe renal disease with oliguria or anuria. Marked cardiac decompensation. Pregnancy.

GI disturbances; headache, dizziness; allergic reactions; raised liver enzyme values; alopecia; bone marrow suppression.

Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.
