Overview
Brief Summary
The purpose of this study is to assess the influence of extracorporeal circulation during cardiac surgery on the optic nerve sheath diameter (ONSD) after the surgery.
Detailed Description
ONSD will be measured before and 1 hour after the surgery and in the morning of day 1 after the surgery. Fluid balance and lactate will be measured too. PONV will be assessed. Patients will be evaluated with MoCA test on the day before surgery and on the day 3 after the surgery for cognitive disfunction.

Outcomes
Primary Outcomes
Ultrasound measuring of optic nerve sheath diameter baseline
Time Frame: Before start of surgery
Baseline optic nerve sheath diameter measurement before start of surgery with a linear ultrasound probe (Scan) in coronal and axial plane
Ultrasound measuring of optic nerve sheath diameter end of surgery
Time Frame: 1 hour after the end of surgery
Optic nerve sheath diameter measurement 1 hour after the end of surgery with a linear ultrasound probe in coronal and axial plane
Ultrasound measuring of optic nerve sheath diameter day 1
Time Frame: day 1 after the surgery
Optic nerve sheath diameter measurement in the morning on day 1 after the surgery with a linear ultrasound probe in coronal and axial plane
Secondary Outcomes
- postoperative cognitive disfunction measured with the MoCA test(on the day before surgery, on day 3 after the surgery)
- postoperative nausea and vomiting (PONV)(during the first 24 hours after surgery)
