Abstract

The present invention discloses one kind of medicine composition for expanding blood volume and its preparation process. The medicine composition includes hydroxyethyl starch, sodium ion, potassium ion, magnesium ion, chlorine ion, and acetate radical or lactate radical ion. The medicine composition is used for preventing and treating hypovolemia and may be used in great dosage infusion without risk of hyperchloremic metabolic acidosis.

Description

technical field [0001] The invention relates to a pharmaceutical composition for expanding blood volume and a preparation method thereof. Background technique [0002] Volume therapy has always been one of the important means in emergency resuscitation, perioperative surgery and critical care medicine. Therefore, choosing the appropriate type of fluid for safe and effective volume therapy is crucial to maintaining the organ function of patients, and to some extent affects the prognosis and outcome of the disease. Crystalloids, colloids, and whole blood are commonly used clinical volume supplements. In recent years, artificial colloids, especially hydroxyethyl starch, have been widely used clinically. Injection containing hydroxyethyl starch is used to maintain circulating blood volume (emovolemia) or to treat hypovolemia, including conditions such as surgery, trauma, burns, and infection. In addition, hydroxyethyl starch can be used as a blood thinner for extracorporeal c...
