Problems solved by technology

Hypertonic solutions such as 7.5% (w / v) sodium chloride and 7.2% sodium chloride, but this hypertonic concentration of sodium chloride has certain toxicity to the body and often leads to complications, such as hypotension, hypertonicity Blood cell rupture, cardiac insufficiency, renal insufficiency, and nervous system disorders
[0005] At present, the existing plasma substitutes can not meet the needs of clinical application well, and a better plasma substitute pharmaceutical composition is needed to be used in the field of first aid for the wounded and sick, especially for the rescue of hemorrhagic shock caused by acute trauma

Abstract

The invention discloses a plasma substitute medicine composition used in first aid and a preparation method thereof. The plasma substitutes medicine composition includes 2-4.5% (w / v) of sodium chloride and 3-7% (w / v) of hydroxyethyl starch, wherein the average molecular weight of the hydroxyethyl starch is 130000 + / - 20000 Dolton. The plasma substitute medicine composition is strong in plasma volume expansion, is durable in effects, is low in tendency of medicine accumulation, is high in safety and is more less in influence on blood coagulation in human body. The plasma substitute medicine composition can be used for treating hemorrhagic shock due to various reasons and can be used for rescue of injury and burn patients. The plasma substitute medicine composition can be used in various operations.

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...
