"Despite the uncertainties, air embolism has served as a reasonably dependable method of execution. After public outcry stopped Nazi gassing of mental patients in 1941, psychiatric institutions were ordered to continue so-called mercy killings by less conspicuous means. A program described as "wild euthanasia" began at the Meseritz-Obrawalde hospital in 1942, with doctors selecting the victims and nurses doing the deed. While most of the murders were carried out with overdoses of sedatives, some patients were injected with air, which usually killed them within minutes. Though thousands of patients died, at trial years after the war 14 nurses claimed they were just following orders and were acquitted. Decades later Germany saw another rash of murders-by-embolism when a nurse confessed to injecting an estimated 60 to 130 milliliters of air into the veins of 15 seriously ill elderly patients. All died."
