Objective:To systematically evaluate the incidence and influencing factors of emergence agitation (EA) after general anesthesia in patients undergoing non-cardiac surgery.Methods:Literature on EA after general anesthesia in adult patients undergoing non-cardiac surgery was electronically retrieved from PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The search period was from the establishment of the database to June 1, 2024. Two researchers independently screened literature, extracted data, conducted quality assessments, and used RevMan 5.3 to perform the Meta-analysis.Results:A total of 22 studies were included, involving 16 853 patients. Meta-analysis indicated that the incidence of EA after general anesthesia in patients undergoing non-cardiac surgery was 18.00%. Advanced age, male, high anesthesia grade, obesity, smoking, hypertension, diabetes, preoperative anxiety, preoperative benzodiazepine use, high preoperative leukocyte, low preoperative serum albumin, prolonged operative time, intraoperative hypothermia, type of surgery, inhalation anesthesia, hypoxemia during emergence, pain during emergence, indwelling urinary catheter, and indwelling drainage tube were risk factors for EA ( P<0.05). The use of dexmedetomidine during surgery and analgesic pump after surgery were protective factors for EA ( P<0.05) . Conclusions:The EA in patients undergoing general anesthesia for non-cardiac surgery is the result of multiple factors acting together. Clinical healthcare providers should enhance their ability to identify risk factors for EA and implement targeted interventions at an early stage to improve the quality of patient awakening and clinical outcomes.

Objective To investigate the incidence and related factors of postoperative delirium in elderly patients undergoing elective noncardiac surgery under general anesthesia. Methods Elderly patients aged ≥65 years old undergoing non-cardiac surgery under general anesthesia from December 31, 2017 to December 31, 2018 were retrospectively analyzed. The patients were divided into delirium group and control group according to whether delirium occurred after surgery. Paired t test was used to compare the laboratory test results between the delirium group and the control group. Logistic regression analysis was used to identify the independent risk factors for delirium after non-cardiac surgery in elderly patients. Results A total of 1 072 elderly patients undergoing elective non-cardiac surgery were enrolled in this study. Delirium occurred in 60 patients, and the incidence of delirium was 5.6%. Multivariate Logistic regression analysis showed that postoperative prothrombin time(PT), preoperative blood glucose, preoperative activated partial thromboplastin time(APTT) and postoperative C-reactive protein(CRP) were independent risk factors for delirium after non-cardiac surgery in elderly patients. Conclusions Postoperative PT, preoperative blood glucose, preoperative APTT and postoperative CRP are independent risk factors for POD in elderly patients undergoing non-cardiac surgery.
