Ukrainian trauma surgeon's all-consuming task during Russia's war.

Petro Nikitin, the lead trauma surgeon at a military hospital in Kyiv, Ukraine, has been working tirelessly to repair the bodies of soldiers injured in the ongoing war with Russia. Nikitin's hospital, like others in the country, is short-staffed due to physicians being pulled away to work in field hospitals closer to the front. Nikitin has become familiar with a range of traumatic injuries, including those caused by explosive weapons such as landmines, artillery shells, and grenades. He typically works from 7:45 a.m. until the work is done, sometimes not leaving until about 11 p.m.
