Brief summary

Hypotension after spinal anesthesia is associated with significant perioperative morbidity and mortality, especially in hypovolemic patients. Ultrasonographic measurement of internal jugular vein (IJV) has been recently shown as effective in predicting the intravascular volume status. The aim was to investigate the reliability of preanesthetic ultrasound measurements of IJV in predicting hypotension after spinal anesthesia.
