Summary

This study looked at whether a simple, non-invasive ultrasound of the internal jugular vein in the neck can help predict a dangerous drop in blood pressure (hypotension) after spinal anesthesia in elderly patients. The study included 70 people aged 65 and older undergoing elective surgery. Researchers measured changes in the vein's size when patients moved from lying flat to having their legs raised, to see if this could identify those at risk.
