Is Regional Oxygen Saturation Effective in Predicting Perfusion Parameters and Patient Outcomes in Liver Resection

Sudden hypotension, which may develop during liver resection operations performed under general anesthesia, can affect the patient satisfaction at a high rate by causing complications during and after the operation as a result of disrupting the blood supply of the tissues. Although there are standard monitoring methods such as blood pressure, heart rate, and oxygen status that show unwanted hypotension during anesthesia, it is possible to show hypotension in the early period with new generation methods. Although there are many clinical studies proving the effectiveness of these methods, these methods have not yet been included in the standard monitoring methods. Our prediction in this study is that the development of intraoperative and postoperative complications in patients who will undergo liver surgery, in whom tissue blood flow is monitored with the help of devices, will be less than in patients who are followed up with traditional methods. If an individual participate in this study, he will not be subjected to any additional procedures other than routine practice during the participant's operation. Before standard general anesthesia for his surgery, heart rate, oxygenation status, blood pressure parameters will be monitored. After the initiation of general anesthesia, the procedures performed in each liver surgery will be applied. In addition, he will be followed by using a probe that allows monitoring of tissue blood flow and reflects a value to the screen, to which it is attached, by simply sticking to his skin.
