Of more than 7000 pregnancy-related maternal deaths in the United States from 2006 to 2015, hemorrhage was a direct cause in 11 percent (Creanga, 2015, 2017; Petersen, 2019). Hemorrhage is also the single most important cause of maternal death worldwide (Goffman, 2016; Oladapo, 2016). Notably, perhaps a third of severe cases of hemorrhage are likely preventable (Lepine, 2020).
