Review Meta Analysis
The impact of general and regional anesthesia on the incidence of post-operative cognitive dysfunction and post-operative delirium: a systematic review with meta-analysis.
Post-operative cognitive complications such as delirium have been consistently associated with poor short and long term outcomes, and the role of anesthesia, particularly the role of general versus regional anesthesia, remains unclear. The objective of this systematic review with meta-analysis was to compare the influence of general, regional, or a combination of anesthesia on the development of Post-Operative Cognitive Dysfunction (POCD) and Post-Operative Delirium (POD). Standard bibliographic databases were searched and complimented by hand searching of original and review article references. ⋯ In conclusion, it appears that general anesthesia, compared to others, may increase the risk of developing POCD; however this has not been shown for POD. Possible reasons for this finding have been explored. This data would advocate for the use of regional anesthesia wherever possible especially in people otherwise vulnerable to developing cognitive symptoms.

Review Meta Analysis
Peri-operative risk management in patients with Alzheimer's disease.
The aim of this review is to identify an evidence-based perioperative management for patients affected by Alzheimer's disease (AD) that are scheduled to undergo surgery. This will minimize the negative effects of anesthesia and postoperative sedation and correct those perioperative variables possibly responsible for a decline in cognitive status and a worsening of AD. ⋯ The potential role of anesthesia, surgery, and postoperative analgosedation as risk factors for development of delirium are herein outlined. Finally, pain assessment instruments, as well as principles of management strategies for postoperative delirium in subjects with AD, are suggested.
