Objective To practice the prevention and treatment of severe bone marrow form and intestine form of acute radiation sickness complicated by bacteria infection for providing an effective method on the treatment of acute radiation sickness. Methods Two patients with severe acute radiation sickness suffered from different infection during treatment. Based on their clinical symptoms, image analysis and the findings of microbiological culture, the patients underwent different anti-bacteria and anti-fungi treatment, and the results were evaluated. Result Repeated multiple bacterial infection companied with fungi infection occurred in the two patients with severe acute radiation sickness during the period of treatment. The bacterial infection was controlled temporarily by an intensively antibacterial and antimycotic treatment, but the fungi infection was uncontrolled. In patient A, acute peritonitis occurred 14 days after exposure, and pulmonary infection occurred 19 days after exposure. The pulmonary infection in patient A was controlled by using antibacterial drugs Tienam and Vancocin, while the patient died of multiple organ failure and fungi infection 33 days after exposure. In patient B, pulmonary infection occurred 17 days after exposure, and the septicemia occurred twice with Gram-negative bacteria at 55th day and 71st day after exposure. The pulmonary infection was controlled provisionally by using antibacterial drugs Tienam and Vancocin, while the patient died of multiple organ failure 75 days after exposure.
