The Relationship Between Hypotension and Tissue O2 in Invasive Eadyn During Anesthesia Induction in Open Heart Surgery

Brief Summary

Our aim is to identify patients who may experience hypotension during anesthesia induction. Intraoperative hemodynamic stability plays an important role in tissue oxygenation. Although the duration of hypotension can be kept short with the necessary interventions, it is important that hypotension is predictable in order to prevent intraoperative complications and postoperative organ damage. 40 patients scheduled for open heart surgery will be monitored from one minute before anesthesia is administered until ten minutes after. Patients will be divided into two groups based on the presence or absence of hypotension during the monitoring period. All patients will be monitored according to a standardized procedure. Demographic data, non-invasive and invasive hemodynamic parameters, primarily Eadyn, and cerebral and renal tissue saturation data will be collected. Moreover, vasopressor administration in response to hypotension will be recorded.
