AI Article Synopsis
- The study assesses the effectiveness of combined epidural anaesthesia/analgesia (EAA) in reducing postoperative delirium (POD) and cognitive dysfunction (POCD) after major non-cardiac surgeries.
- While EAA showed no significant difference in the risk of POD/POCD compared to non-EAA methods, it did result in lower pain scores and reduced postoperative nausea and vomiting.
- Overall, the findings indicate that EAA does not significantly impact the incidence of POD/POCD in these patients, though it may improve postoperative comfort.
Article Abstract
Background: To investigate the efficacy of combined epidural anaesthesia/analgesia (EAA) against postoperative delirium/cognitive dysfunction (POD/POCD) in adults after major non-cardiac surgery under general anaesthesia (GA).
Methods: The databases of PubMed, Google Scholar, Embase and Cochrane Central Register were searched from inception to November 2021 for available randomised controlled trials (RCTs) that assessed the impact of EAA on risk of POD/POCD. The primary outcome was risk of POD/POCD, while the secondary outcomes comprised postoperative pain score, length of hospital stay (LOS), risk of complications, and postoperative nausea/vomiting (PONV).
Results: Meta-analysis of eight studies with a total of 2376 patients (EAA group: 1189 patients; non-EAA group: 1187 patients) revealed no difference in risk of POD/POCD between the EAA and the non-EAA groups [Risk ratio (RR): 0.68; 95% CI: 0.41 to 1.13, p = 0.14, I = 73%], but the certainty of evidence was very low. Nevertheless, the EAA group had lower pain score at postoperative 24 h [mean difference (MD): -1.49, 95% CI: -2.38 to -0.61; I = 98%; five RCTs; n = 476] and risk of PONV (RR = 0.73, 95% CI: 0.57 to 0.93, p = 0.01, I = 0%; three RCTs, 1876 patients) than those in the non-EAA group. Our results showed no significant impact of EAA on the pain score at postoperative 36-72 h, LOS, and risk of complications.
Conclusion: This meta-analysis demonstrated that EAA had no significant impact on the incidence of POD/POCD in patients following non-cardiac surgery.

Purpose Of Review: Postoperative delirium (POD) is a common and serious complication after surgery. It is associated with postoperative neurocognitive disorder (PNCD). The vagal cholinergic anti-inflammatory pathway (CAP) has been hypothesized to play a role in POD/PNCD and may be a target for interventions such as transcutaneous auricular stimulation (taVNS).

Article Synopsis
- * Analyzing 30 studies with over 9,000 participants, results indicated that higher levels of postoperative pain were associated with an increased risk of POD, but there was low certainty in these findings, and there was very low certainty regarding the link between pain and POCD.
- * The study faced challenges due to methodological differences among the included studies, which complicated the pooling of data and assessment of evidence certainty, particularly for chronic postsurgical pain (CPSP) with POD or POCD.
The use of peripheral nerve block decrease incidence of postoperative cognitive dysfunction following orthopedic surgery: A systematic review and meta-analysis.

Article Synopsis
- Postoperative neurocognitive disorders (PNDs), which include postoperative cognitive dysfunction (POCD) and postoperative delirium (POD), are common after orthopedic surgery and can lead to negative outcomes.
- This study examined the effects of combining peripheral nerve block (PNB) with general anesthesia (GA) on the occurrence of POCD and POD compared to using GA alone.
- The findings revealed that combining PNB and GA significantly reduced the incidence of POCD but had no notable impact on POD; it also led to lower opioid use and reduced postoperative nausea and vomiting.
Electroencephalography Monitoring for Preventing Postoperative Delirium and Postoperative Cognitive Decline in Patients Undergoing Cardiothoracic Surgery: A Meta-Analysis.
Rev Cardiovasc Med

Department of Anesthesiology and Perioperative Medicine, The Second Hospital of Anhui Medical University, 230061 Hefei, Anhui, China.
Background: Patients undergoing cardiothoracic surgery frequently encounter perioperative neurocognitive disorders (PND), which can include postoperative delirium (POD) and postoperative cognitive decline (POCD). Currently, there is not enough evidence to support the use of electroencephalograms (EEGs) in preventing POD and POCD among cardiothoracic surgery patients. This meta-analysis examined the importance of EEG monitoring in POD and POCD.

Background: Perioperative neurocognitive disorders (NCD) are poorly characterized in terms of their risk factor profiles. Leptin and adiponectin are adipose-tissue-derived hormones with a role in inflammation and atherosclerosis whose function in perioperative NCD is unclear. Here, we used a cohort of older adults to examine the association of preoperative plasma concentrations of these biomarkers with the risk of perioperative NCD.
