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.

Transthoracic echocardiogram will be performed before the operation and at certain time intervals during the operation.
Ejection fraction
Ejection fraction (EF) measurement will be made with Simpson's method and fractional shortening method.
Time frame: peroperative
intraoperative blood pressure monitoring
systolic, diastolic and median blood pressure values
Time frame: peroperative
cardiac diastolic dysfunction
The echocardiogram will measure the flow velocity between the left atrium and ventricle in cm/s in pulsed wave mode and the E/A ratio will be calculated.
Time frame: peroperative
Entropy
Depth of anesthesia will be measured by placing Entropy sensors on the forehead as needed.
Time frame: peroperative
sedative drug
The drugs used for sedation and their amounts will be recorded.
Time frame: intraoperative
ramsey sedation scale
1. point Awake, restless and/or crying. 2. points Alert, calm, watching his surroundings. 3. points Sleepy but responds to verbal stimuli 4. points Sleepy but immediately responds to glabellar tactile stimuli. 5. points Sleepy but responds slowly to glabellar tactile stimuli. 6. points Does not respond to Alerts.
Time frame: intraoperative
