Clinical Trial Summary

The study targets postoperative delirium in patients undergoing major abdominal surgery, with the aim to evaluate the functional baseline and proteomics implicated in pathogenesis, prevention strategies (such as anesthesia depth monitoring) and incidence in certain population groups.

Outcome

Type Measure Description Time frame Safety issue
Other The influence of POD on length of stay (LOS), unplanned ICU re-admission, cognitive decline and mortality Evaluating the possibility of a correlation between the occurence of POD and prolonged hospitalization, a prerequisite for ICU re-admittance or further cognitive deterioration / mortality. during patient hospitalization
Primary Prediction model for postoperative delirium (POD) in major abdominal surgery Developing an accesible algorithm to anticipate the occurence of postoperative delirium, based on functional baseline and proteomics, in adult patients subjected to major abdominal surgical interventions.
This includes investigating a correlation between a set of risk factors, a panel of biomarkers and the occurrence of postoperative delirium in the enrolled patients, respectively.
3-4 years
Secondary Anesthesia depth monitoring and the incidence of postoperative delirium Assessing the influence of BIS monitoring during general anesthesia on the prevalence of postoperative delirium 0-4 days postoperatively
Secondary Postoperative delirium incidence in surgical patients in the Intensive Care Unit (ICU) setting during ICU hospitalization
Secondary Postoperative delirium incidence in surgical patients - subgroup - communism survivors during ICU hospitalization
Secondary Postoperative delirium incidence in surgical patients - subgroup - patients with no relatives/visitors during ICU hospitalization
