Letting patients drink clear fluids until called to the operating room to shorten pre-surgery fasting

Official title: Quality Improvement Project to Reduce Preoperative Fasting Times Before Elective Procedures

Run by University of Giessen · NCT07488468 · Data updated 2026-11-12

This project will try letting elective procedure patients drink clear liquids until they're called to the operating room to see if fasting times, comfort, and perioperative outcomes improve.

Is this trial a fit for you?

Likely a good fit

Patients scheduled for elective surgery or interventions requiring anesthesiology care (general anesthesia, regional anesthesia, sedation, or anesthesiology standby) at the site are the intended participants, excluding those already sedated or mechanically ventilated.

Probably not a fit

Patients who are already sedated, intubated, or mechanically ventilated, those undergoing emergency procedures, or patients with specific medical orders to remain NPO are unlikely to benefit from this initiative.

What this trial studies

This single-center quality improvement initiative uses a Plan-Do-Study-Act framework to implement a local standard operating procedure allowing clear liquids until patients are called to the operating room. The team will train anesthesiology staff, provide patient fasting instruction cards, and roll out supporting materials such as posters and short screencasts. Fasting durations and selected perioperative outcomes (e.g., fluid intake, postoperative nausea and vomiting, pulmonary complications, and delirium) will be recorded before and after implementation. Data will be analyzed to guide iterative adjustments to the local protocol.

Why it matters

Potential benefit: If successful, patients may have shorter preoperative fasting with less dehydration and nausea, improved comfort, and potentially fewer postoperative complications such as delirium or pulmonary issues.

How similar studies have gone: International guidelines support a 2-hour clear-liquid fast and prior single-center quality-improvement programs have successfully shortened fasting times and improved patient comfort, so this approach builds on existing practice-change evidence.
