Million Anesthesia Cases: Preoperative fasting and perioperative outcomes

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational cohort will analyze perioperative records from the Mass General Brigham Epic electronic health record covering a large sample of cases where patients received general, regional, or sedated anesthesia. Investigators will measure duration of preoperative fasting and link it to patient-reported well-being (anxiety, hunger, thirst), physiologic markers (blood pressure, urine output, glucose values), and clinical events (perioperative aspiration, postoperative nausea/vomiting, hypoglycemia). Inclusion requires a diagnostic or therapeutic procedure with anesthesia and available Epic data; patients not receiving anesthesia or without Epic records will be excluded. The study aims to identify associations between fasting duration and adverse perioperative outcomes to inform safer fasting practices.
