A clinical trial to compare the role of femoral vein and femoral artery diameter ratio with inferior vena cava - aorta diameter ratio in the patients above 50 years of age to predict the fall in blood pressure after giving spinal anaesthesia.

Design outcomes

Primary

Measure	Time frame
The primary outcome will be measured as sensitivity and specificity of femoral vein – femoral artery diameter ratio and inferior vena cava – aorta diameter ratio in predicting hypotension in patients aged 50 years and above. Timepoint: The vitals of patients will be observed every 2 minutes till 30 minutes after spinal anaesthesia administration	—

Secondary

Measure	Time frame
The secondary outcome will be measured as correlation between vessel diameter ratios and severity of hypotension episodes and to explore the potential clinical implications of using vessel diameter ratios as predictors of post spinal anesthesia hypotension, including their role in risk stratification. Timepoint: 30 minutes	—
