[Pay attention to persistent inflammation-immunosuppression-catabolism syndrome in the late stage of severe burns].

With the deepening of researches on organ complications after severe burns and the continuous improvement of monitoring and support technology for organ function, severe burn patients have avoided death in the early and middle to late stages due to shock, infection, etc., and entered the late stage of burns. Due to the failure of timely and effective burn wound healing and long-term exposure and infection of extensive burn wounds, some of these patients were in chronic and critical conditions such as fever, emaciation, and delayed wound healing that are accompanied by decreased immune function, anemia, and hypoproteinemia, etc. It manifested as persistent inflammation-immunosuppression-catabolism syndrome (PICS), leading to prolonged hospitalization and increased long-term mortality. Based on clinical practice of the author's team in burn treatment, this paper briefly expounds the main causes, clinical characteristics, and prevention methods of PICS in the late stage of severe burns of patients, hoping to attract the attention of peers to PICS in the late stage of severe burns.
