Evaluating postoperative delirium in ICU patients after major abdominal surgery

Postoperative Delirium: a Complex Prediction Model in Patients Undergoing Major Abdominal Surgery

Observational Institutul Regional de Gastroenterologie & Hepatologie Prof. dr. Octavian Fodor · NCT05474872

This study looks at patients who have major abdominal surgery to see how often they experience confusion afterward and what factors might contribute to it, while also testing ways to help prevent this issue.

What this trial studies

This observational study focuses on patients undergoing major abdominal surgeries to assess the incidence of postoperative delirium and its associated factors. It aims to evaluate baseline functional status and the role of specific proteins in the pathogenesis of delirium. Additionally, the study will explore prevention strategies, including monitoring anesthesia depth, to mitigate the risk of cognitive impairment in this patient population. The research is conducted at a specialized gastroenterology and hepatology institute in Eastern Europe.

Who should consider this trial

Good fit: Ideal candidates include patients classified as ASA risk I-III who are scheduled for complex digestive surgeries.

Not a fit: Patients who are unable to provide consent, have undergone neurosurgery or cardiac surgery, or have pre-existing dementia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for preventing postoperative delirium, enhancing recovery and cognitive outcomes for patients after major surgery.

How similar studies have performed: While there have been studies on postoperative delirium, this specific approach focusing on proteomics and anesthesia monitoring in this population is relatively novel.
