Echoing down the corridors of eastern Ukraine’s Pokrovsk Perinatal Hospital are the loud cries of tiny Veronika.

Born nearly two months prematurely weighing 1.5 kilograms (3 pounds, 4 ounces), the infant receives oxygen through a nasal tube to help her breathe while ultraviolet lamps inside an incubator treat her jaundice.

Dr. Tetiana Myroshnychenko carefully connects the tubes that allow Veronika to feed on her mother’s stored breast milk and ease her hunger.

Before Russia’s invasion of Ukraine in late February, three hospitals in government-controlled areas of the country’s war-torn Donetsk region had facilities to care for premature babies. One was hit by a Russian airstrike and the other had to close as a result of the fighting ‒ leaving only the maternity hospital in the coal mining town of Pokrovsk still operating.

Myroshnychenko, the site’s only remaining neonatologist, now lives at the hospital. Her 3-year-old son divides the week between staying at the facility and with his father, a coal miner, at home.

The doctor explains why it’s now impossible to leave: Even when the air-raid sirens sound, the babies in the hospital’s above-ground incubation ward cannot be disconnected from their lifesaving machines.
