Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Preoperative fasting aims to reduce the risk of adverse events (eg, inhalation), but may be responsible for dehydration whose consequence is a major hypotension. This problem of hypotension is important because it (MAP \<55 mmHg) is directly correlated to the occurrence of pejorative events on the cardiac and renal level and even more so that the duration of the hypotension is long.
