A doctor with the Yale School of Medicine has just returned from Ukraine where he helped surgeons with wounded soldiers.

Dr. Suresh Mohan said Ukrainian doctors came to Connecticut to learn last fall. Last week, it was Mohan's turn to go to Ukraine and teach.

"I kept waiting for the bombs to drop from the sky," said Mohan. Mohan heard air sirens in Ukraine. He quickly got a real sense that he was in a country at war. "And suddenly they were telling me about the bomb shelter and what to do if the alarm went off," said Mohan. It has been more than three years since Russian invaded Ukraine. "The trauma that these soldiers endured is a different kind of trauma than what we see here in the U.S.," said Mohan. Not only physical trauma, but psychological.

Mohan helped perform almost 15 surgeries with two other surgeons from the U.S. "These are very skilled surgeons. They just have been pulled out of their natural environment and thrown into this new challenge of treating injuries they've never seen or sometimes even working out of their specialty," said Mohan. Mohan specializes in tissue reconstruction. He said the surgeries he performed in Ukraine improved disfigurements and helped soldiers to see, speak, eat and breathe.

He risked his own life to save the lives of others. "Human beings are human beings no matter where they are. We all want the same thing. Everyone wants the war to end," said Mohan. He said he has been invited back to Ukraine in September and is planning to go.
