April 10 — the city of Tsaritsyn was renamed Stalingrad.
October 31 — Mikhail Vasilyevich Frunze died after an unsuccessful ulcer operation. Today, Frunze would not have been sent to the operating table. As it turned out during the surgery, his ulcer had scarred over. But in 1925 there was no equipment that would have allowed doctors to make the correct diagnosis. The medical mistake lay elsewhere. To put the patient to sleep, they had to administer an increased dose of chloroform—60 grams, even though 50 grams could already have led to poisoning. However, some patients tolerated even 100 grams without any particular shock.
Seeing that Frunze was not falling asleep, Alexey Ochkin, who was responsible for the anesthesia, should have stopped the operation, but he continued increasing the doses. In the end the patient fell asleep; the abdominal cavity was opened, examined, and stitched up. Frunze woke up and remained conscious for another three days. The causes of his death were severe chloroform intoxication and the natural decrease in immunity in such a situation, which led to the development of postoperative peritonitis.
