Methylene Blue and Postoperative Neurocognitive Disorders

Effectiveness and Safety of Methylene Blue for Prevention of Postoperative Neurocognitive Disorders in Patients Undergoing Pancreatic Tumor Surgery: A Prospective Randomized Controlled Clinical Trial

Source: ClinicalTrials.gov · Last updated 14 May 2025

Brief summary (registry, in English)

Postoperative Neurocognitive Disorders are the most common neurological complications after major surgery, which are associated with higher increased mortality and morbidity in elderly patients undergoing major surgery. Until now highly effective intervention has not been established yet. Recent preclinical studies suggest neuroinflammation may be linked to pathogensis of (postoperative delirium) POD and postoperative cognitive dysfunction (POCD). As Methylene blue(MB) has neuroprotective and anti-inflammatory properties, and it is a safe drug with long history of clinical use, we propose that inflammation-targeted interventions may be useful to prevent POD/POCD in surgical patients.
