NCT02979275

Brief Summary

Identification of risk factors of acute kidney injury (AKI). It is hypothesized that there might be a correlation between brain oximetry, tissue saturation of thenar muscle and marker of AKI in blood - neutrophil gelatinase-associated lipocalin (NGAL) - measured in blood samples during the first post-op day.

Outcome Measures

Primary Outcomes (1)

  • NGAL

    neutrophil gelatinase-associated lipocalin (NGAL) measured in blood samples

    3 hours after operation

Secondary Outcomes (5)

  • NGAL on second day

    second post-op day morning

  • Cystatin C

    second post-op day morning

  • Serum creatinine

    second post-op day morning

  • Acute renal failure

    30 day / any time after operation before discharge from hospital

  • In hospital mortality

    30 day / any time after operation before discharge from hospital

Study Arms (1)

BRAIN+THENAR MUSCLE INVOS

Patients undergoing open heart surgery on cardiopulmonary bypass.

Procedure: Open heart surgery on cardiopulmonary bypass.

Interventions

Brain oximetry and tissue saturation will be measured during operation. NGAL, cystatin-C, and Acute Kidney Injury Network (AKIN) criteria of AKI will be assessed durin first post-op day.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult patient scheduled for elective on-bypass cardiac surgery (aortic valve surgery, mitral valve surgery with/without tricuspid valve surgery, ascending aorta surgery with/without aortic valve surgery).

You may qualify if:

  • adult patients
  • signed informed consent
  • scheduled for elective on-bypass cardiac surgery (aortic valve surgery, mitral valve surgery with/without tricuspid valve surgery, ascending aorta surgery with/without aortic valve surgery).

You may not qualify if:

  • chronic kidney insufficiency (serum creatinine \>2 mg/dL)
  • active infection (i.e.: endocarditis)
  • shock or tissue hypoperfusion before operation (blood lactate \>3 mmol/L)
  • left ventricle ejection fraction \<25%
  • vancomycin used for infection prophylaxis (i.e.: in immunosuppressed patients)
  • history of ischaemic shock
