Brief Summary: In patients with fluid deficit, vasoconstriction occurs in peripheral tissues and blood circulation is kept in the central area. It causes arterial vasodilation and hemodynamic variability by increasing the blood volume of the extremity due to the sympathectomy occurring after the block. When the investigators classify patients according to VCI-CI, it will be questioned whether there is a difference between patients' block quality and hemodynamic variability.
Detailed Description: VCI-CI helps us to have an idea about the amount of fluid in patients according to the vena cava Inferior (VCI) diameter and the diameter between the inspiring and expiration. Low arterial diameter and high inspiratory and expiratory variability indicate that the patient's fluid volume may be lower. In the measurement of VCI diameter, VCI has visualized in the craniocaudal plane thanks to the transverse ultrasound probe. Changes in VCI diameter are observed depending on the negative pressure in the thoracic area during inspiration and expiration. When the difference between this rate of change is greater than 50%, it indicates that the patient has a fluid deficit. The fact that the VCI diameter is also below 1.5 cm indicates that this amount of fluid requirement is more serious. In this study, the investigators will question whether there is a difference between patients' block quality and hemodynamic variability when they classify patients according to VCI-CI.
