In 1961, surgeon Leonid Rogozov was the only physician stationed on an isolated 12-man Soviet base in Antarctica when he developed appendicitis. He had to remove his appendix himself.
“I didn’t permit myself to think about anything other than the task at hand. It was necessary to steel myself, steel myself firmly and grit my teeth. In the event that I lost consciousness, I’d given Sasha Artemev a syringe and shown him how to give me an injection. I chose a position half sitting. I explained to Zinovy Teplinsky how to hold the mirror. My poor assistants! At the last minute I looked over at them: they stood there in their surgical whites, whiter than white themselves. I was scared too. But when I picked up the needle with the novocaine and gave myself the first injection, somehow I automatically switched into operating mode, and from that point on I didn’t notice anything else.
