Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Incidence of postoperative cognitive decline
Tidsramme: Preoperative baseline to postoperative day 7 or before hospital discharge
|
Postoperative cognitive function will be assessed using the Korean Mini-Mental State Examination (K-MMSE) and the Korean version of the Montreal Cognitive Assessment (MoCA-K).
Both assessments will be performed preoperatively and again on postoperative day 7 or before hospital discharge.
Postoperative cognitive dysfunction will be defined as a decrease of ≥2 points from the preoperative baseline score in either the K-MMSE or MoCA-K.

Change in plasma HMGB1 concentration
Tidsramme: Preoperative baseline through 24 hours after completion of cardiopulmonary bypass
|
Plasma high mobility group box 1 (HMGB1) concentration will be measured at preoperative baseline, 2-4 hours after completion of cardiopulmonary bypass, and 24 hours after completion of cardiopulmonary bypass.
Changes from baseline will be compared between the remimazolam and propofol groups.
Plasma HMGB1 concentration will be measured in pg/mL using the Multiplex bead assay.

Change in plasma GFAP concentration
Tidsramme: Preoperative baseline to 24 hours after completion of cardiopulmonary bypass
|
Plasma glial fibrillary acidic protein (GFAP) concentration will be measured at preoperative baseline and 24 hours after completion of cardiopulmonary bypass.
The change from baseline will be compared between the remimazolam and propofol groups.
GFAP will be analyzed using the Single Molecule Array (Simoa) assay.
