Hydroxyethyl starch (HES) solutions have had a turbulent history as resuscitation fluids.1,2 There was initial optimism that these products would efficiently expand the intravascular space with a prolonged intravascular half-life and therefore would be “volume sparing,” with less edema. However, enthusiasm was tempered when HES solutions were reported to be harmful when administered to critically ill patients, including those with sepsis.2,3 Despite these concerns, HES is still used in surgery under the premise that lower doses infused under strict protocols would be safe.4 In this issue of JAMA, Futier and colleagues5 report the results of the FLASH multicenter randomized clinical trial, which assessed the effects of HES vs saline for fluid resuscitation in patients undergoing major abdominal surgery. The primary end point was a composite of death and occurrence of renal, respiratory, cardiovascular, infectious, or surgical complications. Several secondary and exploratory end points were also reported.
