What this trial studies

This study evaluates the potential of automated pupillometry to predict postoperative delirium in adult patients undergoing elective open cardiac surgery. By measuring various pupillary variables during anesthesia with an automated pupillometer, the researchers aim to identify correlations between these measurements and the occurrence of delirium post-surgery. Patients will be monitored closely in the cardiac intensive care unit after surgery to assess their cognitive status using the Confusion Assessment Method-ICU. The study seeks to validate a new predictive tool for a common complication in cardiac surgery.

Who should consider this trial

Good fit: Ideal candidates are adult patients over 18 years old scheduled for elective open cardiac surgery requiring cardiopulmonary bypass.

Not a fit: Patients under 18, those undergoing emergency surgeries, or individuals with psychiatric disorders or ocular problems may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable method for predicting postoperative delirium, potentially improving patient outcomes and care strategies.

How similar studies have performed: While various predictors for postoperative delirium have been studied, the use of automated pupillometry in this context is novel and has not been extensively tested.
