Treatment and study plan

preoperative ultrasonographic evaluation of right common femoral vein diameter

Diagnostic Test

preoperative ultrasonographic evaluation of right common femoral vein diameter to predict spinal anesthesia-induced hypotension in elderly patients

Primary outcomes

  1. 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.

    Time frame: 30 minutes after spinal anesthesia

Secondary outcomes

  1. Incidence of spinal anesthesia-induced hypotension in elderly

    Time frame: 30 minutes after spinal anesthesia

  2. The sensitivity of the peak velocity of blood flow (mm/s) in the right common femoral vein as measured by ultrasound before anesthesia to predict spinal anesthesia-induced hypotension in elderly patients

    Time frame: 30 minutes after spinal anesthesia
