A Russian woman has died after doctors allegedly placed her on a formalin drip - a solution containing formaldehyde - instead of saline.
Ekaterina Fedyaeva, 27, was undergoing an unspecified but routine surgery at a hospital in Ulyanovsk, in the Volga Federal District of Russia, when medics allegedly filled her IV bag with formalin solution. Formalin is used to prevent corpses from decomposing, reported The Sun.
