Delirium in Elderly Undergoing Cardiac Surgery and the Significance of CholinEsterase Activity (DECCEP)
Delirium in Elderly Undergoing Cardiac Surgery and the Significance of CholinEsterase Activity Measured by Point of Care Method - a Prospective Observational Study
The purpose of this study is to assess the association between the "point-of-care" (POC) measured ChE activity (Acetylcholinesterase (ChE) + Buturylcholinesterase (ChE)) and postoperative delirium in elderly patients undergoing cardiac surgery.
Furthermore the investigators aim to identify factors, which influence the baseline levels and the time course of ChE activity.

Was misst die Studie?
Primäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Acetylcholinesterase (AChE) and buturylcholinesterase (BuChE) activity
Zeitfenster: 5 days
|
The perioperative AChE and BuChE activity will be assessed in the whole blood by a "point-of-care" measuring instrument (ChE check mobile ®) and the association to the incidence and duration of postoperative delirium will be determined.
It will be assessed preoperative and maximum until the 5th postoperative day (POD), minimum until the 3.POD.
|
5 days
|
Delirium
Zeitfenster: 5-45 days
|
Postoperative delirium will be assessed preoperative and daily with the CAM / CAM-ICU test until the 5.POD and on the discharge day from hospital.
The incidence of postoperative delirium will be associated with the perioperative AChE and BuChE time course.
|
5-45 days
