Hydroxyethyl starch Basic information Clinical Uses lnstructions for Use Adverse Reactions and Side Effects Product Name: Hydroxyethyl starch Synonyms: 2-hydroxyethylstarchether;essex1360;2-HYDROXYETHYL STARCH;essexgum1360;ethylexgum2020;hes;hespander;hespanderinjection CAS: 9005-27-0 MF: (C6H10O5)m(C2H5O)n MW: 0 EINECS: 618-410-9 Product Categories: API;Carbohydrates;Carbohydrates A to;Carbohydrates H-LBiochemicals and Reagents;Polysaccharide Mol File: Mol File   Hydroxyethyl starch Chemical Properties Melting point  >224oC (dec.) storage temp.  -20°C solubility  Freely soluble in water and in dimethyl sulfoxide, practically insoluble in anhydrous ethanol. Hydroxyethyl starches are hygroscopic until they reach a water content of about 12 per cent to 15 per cent. form  neat color  White to Off-White CAS DataBase Reference 9005-27-0(CAS DataBase Reference) EPA Substance Registry System Starch, 2-hydroxyethyl ether (9005-27-0)   Safety Information WGK Germany  2 RTECS  WI0410000 MSDS Information Provider Language SigmaAldrich English   Hydroxyethyl starch Usage And Synthesis Clinical Uses Hydroxyethyl starch is often used as a plasma substitute for therapy of hypo- volemia after trauma, burns, infections or during surgery.It is also widely used for hemodilution treatment of cerebral ischemia and of retinal, otogenic or peripheral perfusion disturbances.In treatment of cerebral ischemia, a hypervolemic therapy protocol has been shown to be more effective than an isovolemic infusion. Another indication is the hyperdynamic treatment of vasospasm in subarachnoid hemorrhage.Some of these indications require relatively high dosages to ensure efficacy of therapy.However, during continuous treatment with large volumes of HES, disturbances of coagulation and hemor- rhagic complications are not uncommon. Trumble et al. reported bleeding complications during hetastarch therapy of vasospasm in subarachnoid hemorrhage patients and recommended the use of plasma protein fraction instead.Van den Brink observed coagulopathy under therapy with highly sub- stituted medium molecular weight HES.These disturbances of the coagulation sys-tem were found to be due to an acquired von Willebrand syndrome. lnstructions for Use Suspend in saline(0.9%) or 5% dextrose solution for use. Administer slowly in 5-mL/kg increments to small animals,then reassess and increase the dose to rates listed in the dosing section.Hydroxyethyl starch solutions are used in critical care situations and infused via CRI. Adverse Reactions and Side Effects Most of the serious adverse effects reported, such as kidney injury and coagula- tion abnormalitics,have been observed in human studies and have not been docu- mented with clinical use in veterinary medicine.The use in people has become controversial and caution is advised when using these products in animals,with attention to the most commonly reported problems in people.Hetastarch may cause allergic reactions and hyperosmotic kidney injury.Hydroxyethyl starch solu- tions may affect platelet function and produce coagulation abnormalitics at clini- cally relevant doses for up to 24 hours.The high-molecular-weight hetastarch may alter coagulation and alter viscoelastic measurements and fibrinolysis.Do not use in patients with bleeding problems or preexisting coagulopathies. High-molecular- weight products (10% solutions) have molecular weight more than 200 kDa (kilodaltons)and are associated with higher risk of kidney injury.Tetrastarch solu- tions also may have less tendency to cause coagulopathics than hetastarch.There- fore the current recommendation is to use tetrastarch solutions of 6% and reduced molecular weight(130 kDa). Chemical Properties DS 0.7; Uses blood volume expander Uses Hetastarch, with a trade name of Hespen, is used widely as volume expanders. An intravenous solution of hydroxyethyl starch is used to prevent shock following severe blood loss caused by trauma, surgery, or other problems. Brand name Pentaspan (DuPont Merck). Biochem/physiol Actions Analysis of cDNA clones indicates that ribosome binding protein 1 may exist in different forms due to removal of tandem repeats, or partial intraexonic splicing of RRBP1. The form presented here is lacking the canine p180 ribosome-binding domain, NQGKKAEGAQ, which is tandemly repeated close to the N-terminus in other forms that haven′t been fully characterized. RRBP1 has been excluded as a candidate gene in the cause of Alagille syndrome. Alternate splicing results in multiple transcript variants.

Leader Biochemical Group is a large leader incorporated industry manufacturers and suppliers of advanced refined raw materials From the year of 1996 when our factory was put into production to year of 2020, our group has successively invested in more than 52 factories with shares and subordinates.We focus on manufacture Pharm & chemicals, functional active ingredients, nutritional Ingredients, health care products, cosmetics, pharmaceutical and refined feed, oil, natural plant ingredients industries to provide top quality of GMP standards products.All the invested factories' product lines cover API and intermediates, vitamins, amino acids, plant extracts, daily chemical products, cosmetics raw materials, nutrition and health care products, food additives, feed additives, essential oil products, fine chemical products and agricultural chemical raw materials And flavors and fragrances. Especially in the field of vitamins, amino acids, pharmaceutical raw materials and cosmetic raw materials, we have more than 20 years of production and sales experience. All products meet the requirements of high international export standards and have been recognized by customers all over the world. Our manufacture basement & R&D center located in National Aerospace Economic & Technical Development Zone Xi`an Shaanxi China. Now not only relying on self-cultivation and development as well as maintains good cooperative relations with many famous research institutes and universities in China. Now, we have closely cooperation with Shanghai Institute of Organic Chemistry of Chinese Academy of Science, Beijing Institute of Material Medical of Chinese Academy of Medical Science, China Pharmaceutical University, Zhejiang University. Closely cooperation with them not only integrating Science and technology resources, but also increasing the R&D speed and improving our R&D power. Offering Powerful Tech supporting Platform for group development. Keep serve the manufacture and the market as the R&D central task, focus on the technical research.  Now there are 3 technology R & D platforms including biological extract, microorganism fermentation and chemical synthesis, and can independently research and develop kinds of difficult APIs and pharmaceutical intermediates. With the strong support of China State Institute of Pharmaceutical Industry (hereinafter short for CSIPI), earlier known as Shanghai Institute of Pharmaceutical Industry (SIPI), we have unique advantages in the R & D and industrialization of high-grade, precision and advanced products.  Now our Group technical force is abundant, existing staff more that 1000 people, senior professional and technical staff accounted for more than 50% of the total number of employees, including 15 PhD research and development personnel, 5 master′ S degree in technical and management personnel 9 people. We have advanced equipment like fermentation equipment and technology also extraction, isolation, purification, synthesis with rich production experience and strict quality control system, According to the GMP required, quickly transforming the R&D results to industrial production in time, it is our advantages and our products are exported to North and South America, Europe, Middle East, Africa, and other five continents and scale the forefront in the nation, won good international reputation.  We believe only good quality can bring good cooperation, quality is our key spirit during our production, we are warmly welcome clients and partner from all over the world contact us for everlasting cooperation, Leader will be your strong, sincere and reliable partner in China.
