Preoperative Butyrylcholinesterase Linked to Postoperative Delirium Risk

A recent meta-analysis suggests that lower preoperative butyrylcholinesterase (BuChE) activity is significantly associated with an increased risk of postoperative delirium. While presenting a potential biomarker, other studies indicate that this association might not be independently significant in multivariate analyses, prompting further research. The findings hold global relevance for surgical patient care.
