NCT04706884

Brief Summary

Objective: The objective of the study was to investigate a reverse correlation between blood lactate levels and rSO2, and distinguish between hypoxic and non-hypoxic hyperlactatemia seen in the early postoperative period.

Outcome Measures

Primary Outcomes (1)

  • Differantial Diagnosis of early hyperlectathemia

    To understand whether early hyperlactathemia after cardiopulmonary bypass surgery is due to hypoxic or non-hypoxic causes, we will look at the correlation between blood lactate level and cerebral oxygen saturation (rSO2)

    through study completion, an average of 1 year

Interventions

The rSO2 (cerebral oxygen satutation) was continuously monitored by NIRS (Near infrared spectroscopy) with a sensor positioned on the forehead of the patient

Patients who will undergo elective bypass surgery and extracorporeal circulation

You may qualify if:

  • ASA) II-III patients, aged 43-80 years, undergoing on-pump coronary artery bypass grafting

You may not qualify if:

  • Active congestive cardiac failure, intraoperative death, urgent cardiac surgery or reoperation, hemodynamic instability or need of inotropic support before the operation, the elevation of any parameters preoperatively suggestive of systemic hypoperfusion, coagulopathy, renal failure, hepatic dysfunction, local or systemic infection, and inflammation.
