Research progress of delirium after solid organ transplantation

Delirium after solid organ transplantation is an important factor affecting the prognosis of organ transplant recipients, but it lacks sufficient clinical attention at present. The pathophysiological mechanisms are not yet clear, which are closely related to the type of transplant organ, recipient's age, blood glucose variability, high-dose glucocorticoid therapy, and other factors. It is crucial to identify and early intervene the risk factors for delirium after solid organ transplantation for improving patients’ prognosis. This article reviewed the literature on delirium after solid organ transplantation in recent years at home and abroad, clarified the definition, classification, clinical manifestations, and diagnostic criteria of postoperative delirium, summarized the risk factors for delirium after solid organ transplantation, highlighted the characteristics of transplant recipients that are different from other patients, and summarized their prognosis and prevention and treatment methods. The aim is to enhance clinical attention to delirium after solid organ transplantation and improve the prognosis of recipients.
