Objective:To establish training system for postoperative delirium (POD) assessment and evaluate the efficacy of training for anesthesia nurses.Methods:Sixteen nurse anesthetists of both sexes in our hospital were selected and received the systemic training for POD assessment.The training system included questionnaire survey, theoretical teaching, simulated visit, clinical observation, independent evaluation, centralized question-answering, evaluation of efficacy and random inspection.The level of POD knowledge tests were performed before the training and at the end of the fourth week of independent evaluation, respectively.At week 1 and 4 of independent evaluation, the diagnostic rate of POD and sensitivity and specificity of the assessment were calculated, and Kappa consistency analysis was used to assess the consistency between anesthesia nurses and training group in diagnosis of POD.In the first week of the third month after the end of training, the evaluation results were randomly inspected, the POD diagnosis rate was calculated between the anesthesia nurses and the training group, and the consistency analysis was conducted.Results:Compared with the scores of POD knowledge questionnaire and sensitivity of the assessment of the anesthesia nurses in the first week of training, the scores were significantly increased ( P<0.05), and no significant change was found in the POD diagnosis rate in the fourth week of training ( P>0.05). Compared with the training group, the diagnosis rate of POD of anesthesia nurses was significantly decreased in the first week of training ( P<0.05), and no significant change was found at the fourth week of training ( P>0.05). In the first and fourth weeks of training, the Kappa value of anesthesia nurses and the training group was 0.676 and 0.954 ( P<0.001), respectively.In the first week of the third month after the end of training, the Kappa value between anesthesia nurses and the training group in diagnosis of POD was 0.862 ( P<0.05). Conclusion:The training system of POD assessment has been successfully established, and the standardized anesthesia nurses training of POD has been achieved with good results.

Objective:To evaluate the relationship between prognostic nutritional index (PNI) and myocardial injury after non-cardiac surgery (MINS).Methods:This was a retrospective cohort study. The clinical data of adult patients ( n=2 203) who underwent liver resection surgery with general anesthesia at our center from January 2016 to August 2019 were retrospectively collected. The predictive value of preoperative PNI for MINS and the optimal cut-off value of PNI were evaluated and determined according to the receiver operating characteristic curve, and the patients were divided into 2 groups based on the cut-off value: high PNI group and low PNI group. Logistic regression analyses were applied to investigate the relationship between preoperative PNI and MINS. According to the same inclusion and exclusion criteria, the clinical data of patients at our center from January 2022 to December 2023 were collected as the validation set ( n=2 525), and they were grouped using the same PNI cutoff value. Logistic regression analyses were used to verify the relationship between PNI and MINS. Results:The receiver operating characteristic curve analysis showed that the area under the curve of preoperative PNI for predicting MINS was 0.651 (95% confidence interval [ CI] 0.602-0.699), with an optimal cut-off value of 46.193, and the specificity and sensitivity were 0.729 and 0.519 respectively. The integer 46 was considered as the optimal cutoff value for PNI, and the patients were divided into low PNI group (PNI<46, n=606) and high PNI group (PNI≥46, n=1 597). Both univariate and multivariate logistic regression analyses showed that preoperative low PNI was an independent risk factor for the occurrence of MINS (univariate: OR=2.873, 95% CI 2.063-4.003, P<0.001; multivariate: OR=1.844, 95% CI 1.241-2.600, P=0.003). The results in the validation set were still robust (univariate: OR=2.694, 95% CI 1.890-3.833, P<0.001; multivariate: OR=1.602, 95% CI 1.071-2.385, P=0.021). Conclusions:Preoperative low-level PNI is an independent risk factor for MINS, with a certain predictive value.
