HES200/0.5：其注射液具有起效快而强的扩容作用，能维持中等强度扩容作用达4小时，能较完全地从肾脏清除，在血浆和组织的蓄积较少，对凝血功能影响小，能够改善微循环。

　　HES200/0.5: The injection has rapid and strong expansion effect. At moderate intensity, the expansion effect can be maintained up to 4 hours. It can be completely removed from the kidney with low accumulation in plasma and tissues. It has little effect on blood coagulation and can improve microcirculation.

　　除满足日常临床需求外，在突发大量人员伤亡事件、战争及地震等自然灾害的情况下，HES制剂的需求尤为迫切。人血浆在无电、缺水的情况下，保存时间短，且存在血型配型问题，不便使用，该产品可常温保存，无需配型，在上述情况中是最佳急救输血用品。汶川特大地震发生后，该产品在国家紧急采购药品名单中列第一位。

　　In addition to daily clinical usage, HES preparations are in great demand during large scale emergencies such as accident, war and natural disaster. On these occasions, human plasma has short storage life due to power and water shortages and mandatory blood type compatibility also makes it inconvenient to use. While in comparison HES preparations can be stored at room temperature and there is no specific requirement on blood type compatibility, making it the best choice for emergency blood supply. Immediately after Wenchuan earthquake in 2008, it was ranked as the top priority in the purchasing list of national emergency medicines.
