Clinical Trial Summary

During general anesthesia, hypotension might occur during positional change. It is reported that hypotension after positional change from supine to prone is mainly caused by the decrease in preload. The investigators aimed to investigate whether dynamic arterial elastance might predict hypotension associated with positional change from supine to prone.
