Preoperative Fasting and Hypotension Clinical Trial
Official title:
The Influence of Duration of Fluid Abstinence on Hypotension During General Anaesthesia Induction for Traumatic Hip Surgery in the Elderly
This study aims to determine if prolonged fasting represents an independent risk factor for hypotension during induction of general anesthesia in the elderly.
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. ;
