Evaluation of Postoperative Delirium

Evaluation of Postoperative Delirium in Cardiac Surgery Patients With the SDACS Screening Tool: A Multicenter-Multiphase Study

This study developed and validated the SDACS screening tool to predict postoperative delirium in cardiac surgery patients. Conducted across three academic hospitals with 920 participants, it identified four key predictors: chronic opioid use, hearing impairment, benzodiazepine history, and poor postoperative sleep. The tool demonstrated strong predictive power (AUC = 0.897), offering clinicians a practical instrument to guide early interventions.

Vasoplegic Syndrome in Cardiac Surgery: Bridging Therapeutic Gaps with Best Practices and Future Research

This article explores vasoplegic syndrome (VS), a serious complication following cardiac surgery involving cardiopulmonary bypass. It discusses inconsistent definitions, risk factors, and treatment strategies. Methylene blue emerges as a promising therapy due to its ability to counteract the nitric oxide-cGMP pathway. The authors advocate for standardized definitions, early intervention, and large-scale trials to validate therapeutic protocols.
