Predicting low blood pressure after spinal anesthesia in elderly patients
Can Caval-aorta Index and Perfusion Index Predict Hypotension After Spinal Anaesthesia in Elderly Patients Undergoing Lower Extremity Surgery?
This study is testing if certain measurements can help predict low blood pressure in older patients after they receive spinal anesthesia for leg surgeries.

What this trial studies
This observational study aims to predict hypotension in elderly patients undergoing elective lower extremity surgeries with spinal anesthesia by utilizing the caval aorta index and perfusion index. It will involve 190 patients over the age of 60, who will be monitored for various physiological parameters before and during the procedure. Measurements will include heart rate, blood pressure, and indices obtained through ultrasonography and non-invasive pulse oximetry. The study seeks to enhance patient safety by identifying those at risk of hypotension post-anesthesia.
Who should consider this trial
Good fit: Ideal candidates are elderly patients over 60 years old scheduled for elective surgeries in a supine position.
Not a fit: Patients who may not benefit include those with contraindications to spinal anesthesia or those undergoing emergency surgeries.
Why it matters
Potential benefit: If successful, this study could lead to improved monitoring and management of hypotension in elderly patients undergoing spinal anesthesia.
How similar studies have performed: While similar studies have explored monitoring techniques in anesthesia, this specific approach using caval aorta and perfusion indices in the elderly is relatively novel.
