Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to demonstrate that preoperative fasting does not increase the rate of lowered blood volume (defined by a variation of 15% ΔITV during a leg lift) in patients undergoing surgery.
