Advances in the Study of Risk Factors for Postoperative Subdelirium
Objective:Postoperative subsyndromal delirium(PSSD)is a relatively common postoperative complication in surgical patients and is associated with a variety of adverse outcomes,including prolonged postoperative hospitalization,decreased cognitive function,and increased mortality.There is a temporary lack of effective preventive and therapeutic measures in clinical practice,its symptoms are insidious and not easy to be recognized,and there is a lack of clinical awareness of PSSD,which increases the difficulty of managing patients with postoperative PSSD.The study provides a reference for early detection and effective prevention of PSSD by reviewing the national and international literature on postoperative subdelirium research.Methods:A systematic review of the current status and risk factors for the occurrence of PSSD was conducted through a literature search.Results:The risk factors for the development of PSSD were summarized in terms of sociodemographic factors,preoperative,intraoperative,and postoperative factors,such as advanced age,literacy level,ability to perform activities of daily living,cognitive functioning,nutritional status,medication use,preoperative comorbidities,duration of the procedure,postoperative pain,infections,and physical constraints,respectively.Conclusion:The high incidence and danger of postoperative subdelirium is the result of a multifactorial combination of factors,and clinical workers should strengthen the attention and management of high-risk PSSD patients to promote the early recovery of postoperative patients.
