Kolosinskyi Andrii Volodymyrovych was born on September 9, 1994 in the family of doctors Volodymyr and Oksana. After graduating from school in 2012, he entered the Ternopil State Medical University, and in 2018 – the Ukrainian Military Medical Academy. He chose to specialize in anesthesiology. Since June 2021, he served as a resident of the Department of Anesthesiology, Intensive Care and Intensive Care at the Mariupol Military Hospital. Since February 24, 2022, he provided medical assistance to wounded/injured servicemen and civilians. Dozens, and sometimes hundreds, of patients were admitted to the Mariupol military hospital every day, complex surgical interventions were performed, so Andrii and his colleagues had to work in dangerous conditions under constant fire from aircraft, artillery and other types of weapons. After another aerial bombardment on March 16, 2022, the hospital was destroyed. Andriy, together with part of the doctors of hospital No. 555, moved to the “Azovstal” plant, where they continued to provide medical assistance to the wounded and injured. Conditions at the factory were difficult: limited supplies of food, drinking water, and a minimal amount of medicine. Andriy with his wife Nina and colleagues worked around the clock, without rest, and sometimes without sleep at all. Despite life-threatening conditions, constant exhaustion and fatigue, they provided qualified medical care until May 18, 2022, when they were captured. During Andrii’s stay in captivity, the family received a letter dated November 2, 2022. Since then, there is no information about his health and condition. His wife Nina, parents and old grandmother are waiting for Andrii at home.
