Abstract

The invention discloses a first-aid plasma substitute medicine composition and a preparation method thereof. The medicine composition includes 2-6% (w/v) of sodium chloride and 4-10% (w/v) of hydroxyethyl starch, wherein the average molecular weight of the hydroxyethyl starch is 200000 +/- 20000 Dolton. The medicine composition is strong in plasma volume expansion effect, is durable in effect, is low in tendency of medicine accumulation, is high in safety and is less in influence on blood clotting in human body. The medicine composition can be used for treating hemorrhagic shock due to various factors, can be used in first aid of patient suffered from trauma and burn as a plasma substitute, and is employed as the plasma substitute in various surgery.

Description

technical field [0001] The invention relates to a blood plasma replacement pharmaceutical composition for emergency use and a preparation method thereof, belonging to the technical field of pharmaceutical compositions. Background technique [0002] The traditional resuscitation of hemorrhagic shock is to use isotonic crystalloid and / or colloid fluid to infuse early, quickly, and in sufficient quantities, with the goal of restoring hemodynamics as soon as possible. ), and even developed into multiple organ dysfunction syndrome (MODS). Acute respiratory distress syndrome (ARDS) and MODS are currently the main causes of delayed death after resuscitation of trauma-hemorrhagic shock. Resuscitation methods that can reduce the inflammatory response and organ damage after resuscitation are the current focus of attention in the treatment of hemorrhagic shock. [0003] Compared with isotonic solutions, hypertonic solutions have the advantages of inhibiting the activation of neutroph...
