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.
Interventions
ultrasound measurement of the optic nerve sheath diameter
MoCA test is a short bedside test for measuring cognitive disfunction

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ultrasound measuring of optic nerve sheath diameter baseline | 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 | 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 | 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
| Measure | Time frame | Description |
|---|---|---|
| postoperative cognitive disfunction measured with the MoCA test | on the day before surgery, on day 3 after the surgery | MoCA test is a validated test for cognitive disfunction, especially in patients who are elderly than 60 years, the study is comparing the MoCA test values on the day before surgery with the values on day 3 after the surgery |
| postoperative nausea and vomiting (PONV) | during the first 24 hours after surgery | Postoperative nausea and vomiting is common after cardiac surgery, the occurrence of postoperative nausea and vomiting will be recorded |
