Abstract Background Neurocognitive complications seriously affect long-term health-related quality of life in patients after liver transplantation, but what was it like during the transplant? There has been little related research,so it is very necessary to understand the changes in cognition during the perioperative period. Methods This observational study included patients with end-stage liver disease who are waiting for liver transplantation in our center. We performed the individual cognitive function investigation before and one week after successful surgery,then analyze the changes between them and further explore possible ones that cause perioperative cognitive dysfunction among several factors. Results From December 2018 to November 2019, there are 70 patients completed all the investgation. Compared with preoperative cognitive performance, 29 patients experienced deterioration, 14 patients showed significant improvement, and 27 patients remained unchanged. Multi-factor analysis results showed that, a mean arterial pressure <80 mmHg (p=0.035) during the reperfusion phase, sufentanil dosage <1.5 µg kg -1 (p=0.027), and blood transfusion volume >70 ml kg -1 (p=0.047) were closely related to early postoperative cognitive dysfunction. Conclusions The incidences of deterioration, maintenance, and improvement in cognitive function were 41.6%, 38.4%, and 20%, respectively. Massive blood transfusion, hypotension during the reperfusion phase, insufficient intra-operative analgesia, and lower anesthesia depth may be the independent pathogenic factors for deteriorated cognitive function.

Acupoint Stimulation

Background: No specific treatment is available for postoperative cognitive dysfunction (POCD). Recently, interest in the prevention of POCD during the perioperative period has increased. Although some studies suggest that transcutaneous electrical acupoint stimulation (TEAS) may be beneficial, the relevant evidence remains uncertain.Objective: To evaluate the preventive effects of TEAS on POCD.Methods: Seven databases including PubMed, EMBASE, CENTRAL, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Wanfang Database, and Chinese Biomedical Literature Database (CBM) were electronically searched up to April 2021. Two reviewers independently selected the studies, collected data, and assessed the risks of bias and grading of recommendations, assessment, development, and evaluations certainty of the evidence. A meta-analysis of the incidence of POCD, cognitive function score, pain, adverse reactions, and length of hospital stay after surgery was also performed.Results: Twenty-nine randomized controlled trials with 1,994 participants were included. The results of the meta-analysis showed that the TEAS group has a significantly lower incidence of POCD compared with the control group on postoperative days 1 [OR = 0.33 (95%CI: 0.23, 0.47); p &lt; 0.001, I2 = 0%, moderate certainty], 3 [OR = 0.38 (95%CI: 0.29, 0.50); p &lt; 0.001, I2 = 0%, low certainty], and 7 [OR = 0.51 (95%CI: 0.32, 0.81); p = 0.005, I2 = 0%, low certainty] but not on day 5 (p &gt; 0.05, low certainty). Moreover, TEAS improved the Mini-Mental State Examination scores on postoperative days 1, 3, and 7 [MD = 2.44 (95%CI: 1.61, 3.27); p &lt; 0.001, I2 = 93%, low certainty]; [MD = 2.07 (95%CI: 1.53, 2.62); p &lt; 0.001, I2 = 87%, low certainty]; and [MD = 0.49 (95%CI: 0.18, 0.79); p = 0.002, I2 = 21%, low certainty], respectively, but not on day 5 (p &gt; 0.05, very low certainty). TEAS promoted a postoperative analgesic effect within 24 h after surgery. Furthermore, patients receiving TEAS showed a lower incidence of postoperative nausea and vomiting and a shorter hospital stay.Conclusions: Limited evidence suggests that the application of TEAS in the perioperative period is associated with a reduced POCD rate and a protected early postoperative cognitive function.

Postoperative Cognitive Decline

Perioperative neurocognitive disorders (PNDs) refer to cognitive decline identified in the preoperative or postoperative period. It has been reported that the incidence of postoperative neurocognitive impairment after noncardiac surgery in patients older than 65 at 1 week was 25.8∼41.4%, and at 3 months 9.9∼12.7%. PNDs will last months or even develop to permanent dementia, leading to prolonged hospital stays, reduced quality of life, and increased mortality within 1 year. Despite the high incidence and poor prognosis of PNDs in the aged population, no effective clinical prediction model has been established to predict postoperative cognitive decline preoperatively. To develop a clinical prediction model for postoperative neurocognitive dysfunction, a prospective observational study (Clinical trial registration number: ChiCTR2000036304) will be performed in the Shanghai General Hospital during January 2021 to October 2022. A sample size of 675 patients aged &#x3e;65 years old, male or female, and scheduled for elective major noncardiac surgery will be recruited. A battery of neuropsychological tests will be used to test the cognitive function of patients at 1 week, 1 month, and 3 months postoperatively. We will evaluate the associations of PNDs with a bunch of candidate predictors including general characteristics of patients, blood biomarkers, indices associated with anesthesia and surgery, retinal nerve-fiber layer thickness, and frailty index to develop the clinical prediction model by using multiple logistic regression analysis and least absolute shrinkage and the selection operator (LASSO) method. The <i>k</i>-fold cross-validation method will be utilized to validate the clinical prediction model. In conclusion, this study was aimed to develop a clinical prediction model for postoperative cognitive dysfunction of old patients. It is anticipated that the knowledge gained from this study will facilitate clinical decision-making for anesthetists and surgeons managing the aged patients undergoing noncardiac surgery.

OBJECTIVESurgical trauma is known to result in systemic inflammatory changes that can lead to postoperative cognitive dysfunction. In the present study, the authors compared the effects of an epidural anesthesia protocol to those of traditional anesthesia with regard to postoperative inflammatory changes, cellular immunity, and cognitive dysfunction.METHODSForty-eight patients, ages 45–60 years, underwent multilevel thoracolumbar decompression and fusion and were randomly assigned to one of two groups: group 1 (27 patients) had combined epidural and general anesthesia, followed by epidural analgesia for 48 hours after surgery, and group 2 (21 patients) had general anesthesia, followed by traditional opioid pain management after surgery. At multiple time points, data on pain control, cognitive function, cellular immunity, and inflammatory markers were collected.RESULTSGroup 1 patients demonstrated lower pain levels, less systemic inflammation, less cellular immune dysfunction, and less postoperative cognitive dysfunction than group 2 patients.CONCLUSIONSThe use of combined epidural and general anesthesia followed by postoperative epidural analgesia during the first 48 hours after multilevel thoracolumbar decompression and fusion surgery had a significant positive effect on pain management, cellular immune function, systemic inflammation, and postoperative cognitive function.Clinical trial registration no.: 115080510080 (http://rosrid.ru)

ObjectiveThis study aimed to explore the influence of coronary artery bypass grafting (CABG) on both postoperative cognitive dysfunction and quality of life (QoL) and the association between the two patient-related outcomes.MethodsIn a prospective, observational cohort study, patients with elective, isolated CABG were included. Cognitive function was assessed using the Cogstate computerised cognitive test battery preoperatively, 3 days and 6 months after surgery. QoL was measured preoperatively and at 6 months using the RAND-36 questionnaire including the Physical Component Score (PCS) and the Mental Component Score (MCS). Regression analysis, with adjustment for confounders, was used to evaluate the association between postoperative cognitive dysfunction and QoL.ResultsA total of 142 patients were included in the study. Evidence of persistent cognitive dysfunction was observed in 33% of patients after 6 months. At 6 months, the PCS had improved in 59% and decreased in 21% of patients, and the MCS increased in 49% and decreased in 29%. Postoperative cognitive changes were not associated with QoL scores.ConclusionsPostoperative cognitive dysfunction and decreased QoL are common 6 months after surgery, although cognitive function and QoL were found to have improved in many patients at 6 months of follow-up. Impaired cognitive function is not associated with impaired QoL at 6 months.Trial registration numberNCT03774342.

Postoperative cognitive dysfunction increases mortality and morbidity in perioperative patients. Numerous studies have demonstrated that multiple surgery/anesthesia during the neurodevelopmental period affects cognitive function, whereas a single anesthesia/surgery rarely causes cognitive dysfunction in adults. However, whether adults who undergo multiple anesthesia/surgery over a short period will experience cognitive dysfunction remains unclear. In this study, central nervous system inflammation and changes in cholinergic markers were investigated in adult mice subjected to multiple laparotomy procedures over a short period of time. The results showed that despite the increased expression of IL-6 and TNF-α in the hippocampus after multiple operations and the activation of microglia, multiple anesthesia/surgery did not cause a decline in cognitive function in adult mice. There were no changes in the cholinergic markers after multiple anesthesia/surgery.

Background. The issue of analysis of diagnostic criteria and adequate neuroprotective management of postsurgery cognitive dysfunction in abdominal oncosurgery, depending on the degree and structure of disorders, remains unresolved, determining its relevance. Purpose – assessing the postsurgery cognitive dysfunction in patients with neoplasms of the abdominal cavity and management of possible disorders with citicoline depending on the level of general cognitive deficit. Materials and methods. TThe study was conducted at the premises of departments for patients of surgical profile of Municipal Institution “Kharkov City Clinical Hospital of Ambulance and Emergency Care named after Professor O.I. Meshchaninov”. To achieve the aim of the study, 80 patients with abdominal neoplasms who underwent surgery under general anesthesia using propofol and fentanyl were examined. Results and discussion. Based on the comprehensive clinical study and anal- ysis of the mechanisms of formation of postsurgery cognitive dysfunction in patients of oncosurgical profile after surgery under general anesthesia, we suggested directions and schemes for managing postsurgery cognitive dysfunction by means of the developed clinical diagnostic criterion, which is essential in forming individual scheme of treating patients in postsurgery period. Conclusions. Based on the analysis of data on the state of cognitive function changes, comparing the postsurgery period with the preoperative state, a differentiated approach to intensive neuroprotective therapy of postoperative cognitive dysfunction was developed. The technique of intensive neuroprotective   therapy   of   postsurgery   cognitive   dysfunction in patients with abdominal neoplasms, undergoing surgery under general anesthesia, was suggested.

Objective: Postoperative cognitive dysfunction (POCD) can feature a wide spectrum of clinical symptoms, from asymptomatic to debilitating dementia, that lead to increased dependence, lower quality of life, morbidity, and mortality. Protein S100B is a direct marker for neuronal cell damage. We aimed to evaluate S100B as a biomarker for predicting POCD following open-heart surgery. Methods: This was an observational-analytic study to assess changes of the S100B level following open-heart surgery in Cipto Mangunkusumo Hospital, Jakarta. All subjects underwent cognitive function evaluations that consisted of six psychometric tests on the day prior to surgery and five days after surgery. Cognitive dysfunction was determined if there was a>20% cognitive score drop from baseline values in at least two tests. Blood samples for S100B were obtained (1) before the induction of anesthesia and (2) six hours after surgery. Samples were analyzed using enzyme-linked immunosorbent assay for S100B. All data were analyzed using SPSS 20. Results: Among the 55 subjects analyzed, 31 (56.4%) were found to have a decline in cognitive function. There were no differences in baseline characteristics, comorbidities, and perioperative data. Oxygen contents also did not show significant differences at any time. The S100B levels in all subjects increased. This increase was>1.5x higher in subjects with POCD compared to those without POCD (2.15[0.22–60.03] vs. 1.33[0.15–19.77] ng/ml, p = 0.16). However, this difference was not statistically significant. Conclusion: This study showed that serum S100B is higher in POCD patients and has the potential to be a biomarker for predicting POCD after open-heart surgery.

Objectives To investigate the effects of electroacupuncture in regulating astrocytes and oxidative stress in a rat model of postoperative cognitive dysfunction (POCD). Methods Male aged Sprague-Dawley rats were randomized to undergo left hepatic lobe resection to induce POCD, followed by either electroacupuncture or no treatment; or similar surgery without left lobe resection or electroacupuncture (sham). Postsurgical cognitive function, hippocampal astrocyte number and oxidative stress indicators were measured. Results At days 1, 3 and 7 following surgery, escape latency was significantly shorter and platform crossing frequency was increased with electroacupuncture versus other groups. At postoperative day 1, the electroacupuncture group showed significantly fewer glial fibrillary acidic protein (GFAP)-positive hippocampal astrocytes versus the POCD model group. In POCD rats, electroacupuncture significantly decreased serum S100 calcium binding protein B and neuron-specific enolase levels, and increased brain-derived neurotrophic factor and glial cell-derived neurotrophic factor levels, at days 1, 3 and 7. Electroacupuncture significantly attenuated the hippocampal POCD-induced increase in malondialdehyde and decreased superoxide dismutase levels at day 1 following surgery. Conclusion Electroacupuncture may improve cognitive function in rats with POCD by reducing hippocampal GFAP-positive astrocyte number and suppressing oxidative stress.
