肝移植后感染的时间进程与流行病学特征OA

Despite the increasing standardization of surgical techniques and prevention strategies,infection still remains the main cause of complications and death in liver transplant recipients.Post-operative infection exhibits specific pathogenic characteristics at different stages after transplant:in the early stage(within 1 month after trans-plant),surgery-related infection and donor-derived infection are predominant,in the middle stage(2-6 months after transplant),the risk of opportunistic infection reaches its peak,and in the late stage(6 months after trans-plant),community-associated infection is predominant.Through comprehensive analysis of recent research,this paper systematically elaborates the pathogenic and epidemiological characteristics of infection in different stages after liver transplant,as well as the differences in infection patterns among populations in different regions,aiming to provide theoretical basis for optimizing infection surveillance as well as prevention and control strategies,and improving patients'prognosis.
