Conditions

Cardiac Disease, Cardiac Valve Disease

Keywords

extracorporeal circulation, otpic nerve sheath diameter, postoperative cognitive disfunction, postoperative nausea and vomiting

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

Design outcomes

Primary

MeasureTime frameDescription
Ultrasound measuring of optic nerve sheath diameter baselineBefore start of surgeryBaseline 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 surgery1 hour after the end of surgeryOptic 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 1day 1 after the surgeryOptic nerve sheath diameter measurement in the morning on day 1 after the surgery with a linear ultrasound probe in coronal and axial plane

Secondary

MeasureTime frameDescription
postoperative cognitive disfunction measured with the MoCA teston the day before surgery, on day 3 after the surgeryMoCA 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 surgeryPostoperative nausea and vomiting is common after cardiac surgery, the occurrence of postoperative nausea and vomiting will be recorded
