Liver transplant recipients often have low immunity due to their underlying diseases and the need for routine use of immunosuppressants to resist rejection after surgery, making them highly susceptible to perioperative infections. Bacterial and fungal infections are the main causes of high mortality after liver transplantation, so it is extremely important to strengthen the prevention of infection after liver transplantation. At present, there is no consensus on the prevention of infection during the perioperative period of liver transplantation. This article provides a brief review of the susceptibility factors, common infection sites, types of pathogens, and related antibacterial strategies for perioperative infection in liver transplantation, to provide reference for the prevention and use of antibiotics during the perioperative period of liver transplantation.
