Study Details

Study Description

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.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: ultrasound measurement of the optic nerve sheath diameter
  • Diagnostic Test: MoCA test

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.

Arms and Interventions

Arm Intervention/Treatment
standard cardiopulmonary bypass

patients 18 year or older undergoing heart surgery with standard cardiopulmonary bypass

Diagnostic Test: ultrasound measurement of the optic nerve sheath diameter
ultrasound measurement of the optic nerve sheath diameter

Diagnostic Test: MoCA test
MoCA test is a short bedside test for measuring cognitive disfunction

mini-cardiopulmonary bypass

patients 18 year or older undergoing heart surgery with standard mini-cardiopulmonary bypass

Diagnostic Test: ultrasound measurement of the optic nerve sheath diameter
ultrasound measurement of the optic nerve sheath diameter

Diagnostic Test: MoCA test
MoCA test is a short bedside test for measuring cognitive disfunction

Outcome Measures

Primary Outcome Measures

  1. 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

  2. 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

  3. 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 Outcome Measures

  1. 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

  2. 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
