Conditions

Femur Fracture, Spinal Anesthesia, Lumbar Plexus Block

Brief summary

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.

Detailed description

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.

Interventions

DEVICETransthoracic echocardiogram

Transthoracic echocardiogram will be performed before the operation and at certain time intervals during the operation.

Design outcomes

Primary

Measure	Time frame	Description
Ejection fraction	peroperative	Ejection fraction (EF) measurement will be made with Simpson's method and fractional shortening method.

Secondary

Measure	Time frame	Description
intraoperative blood pressure monitoring	peroperative	systolic, diastolic and median blood pressure values
cardiac diastolic dysfunction	peroperative	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.
Entropy	peroperative	Depth of anesthesia will be measured by placing Entropy sensors on the forehead as needed.
sedative drug	intraoperative	The drugs used for sedation and their amounts will be recorded.
ramsey sedation scale	intraoperative	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.
