Preoperative Ultrasonographic Evaluation of the Right Common Femoral Vein Diameter for Predicting Spinal Anesthesia-induced Hypotension in Elderly Patients

Preoperative Ultrasonographic Evaluation of the Right Common Femoral Vein Diameter for Predicting Spinal Anesthesia-induced Hypotension in Elderly Patients. A Prospective Observational Study.

In this study we will determine the ability of preoperative ultrasonographic evaluation of the right common femoral vein diameter to predict spinal anesthesia-induced hypotension in elderly patients.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
The sensitivity of the transverse diameter (mm) value of the right common femoral vein as measured by ultrasound before anesthesia to predict spinal aneshesia-induced hypotension in elderly patients.	30 minutes after spinal anesthesia

Secondary Outcome Measures

Outcome Measure	Time Frame
