Nerve blocks applied with neuraxial anesthesia and ultrasonography are used for many operations today. Neuraxial blocks cause varying degrees of decrease in the blood pressure level of the patients. Peripheral blocks may be preferred to avoid the cardiac effects of the neuraxial anesthesia method.
The hypothesis of this study was that spinal anesthesia applied in intertrochanteric femoral fracture operations caused hypotension by lowering the cardiac ejection fraction.
In our study, The investigators aimed to find out the effect of different regional anesthesia methods on the cardiac function of the patients by echocardiography.
