Hydroxyethyl starch (HES/HAES), sold under the brand name Voluven among others, is a nonionic starch derivative, used as a volume expander in intravenous therapy. The use of HES on critically ill patients is associated with an increased risk of death and kidney problems.[2][3]
HES is a general term and can be sub-classified according to average molecular weight, molar substitution, concentration, C2/C6 ratio and Maximum Daily Dose.[4] The European Medicines Agency commenced in June 2013 the process of agreeing to reduced indications which was completed in October 2013.[5] The process of full withdrawal in the EU was expected to complete in 2018.
