This single-center quality improvement project evaluates preoperative fasting times before elective procedures requiring anesthesiology care. The project aims to reduce prolonged fasting for clear fluids by implementing a local standard operating procedure (SOP) allowing patients to drink clear liquids until being called to the operating room ("drink until called"), supported by staff education and fasting instruction cards. Fasting times and selected perioperative outcomes will be assessed before and after implementation.
All patients elective surgery or intervention requiring with anesthesiology care general anesthesia, regional anesthesia, sedation, or anesthesiology stand-by
Already sedated, intubated, and mechanically ventilated patients
The study population includes all patients undergoing elective procedures requiring anesthesiology care (general anesthesia, regional anesthesia, sedation, or anesthesiology standby) at University Hospital Giessen during the predefined pre- and post-implementation data collection periods. Patients who are already sedated, intubated, and mechanically ventilated at the time of anesthesia induction are excluded.
