入选标准
- •Patients age 18 or older, admitted to the ICU, requiring general anesthesia or sedation for a procedure with a pre-existing, cuffed endotracheal or tracheostomy tube. Most patients admitted to the ICU would be unable to consent.
排除标准
- •Known upper gastrointestinal anatomical problem that would prevent accurate estimation of gastric volume, gastric perforation, pregnancy beyond the first trimester.
- •Lack of a pre-existing, cuffed endotracheal or tracheostomy tube.
研究组 & 干预措施
Standard ASA NPO Protocol
Patients will be made NPO at midnight prior to date of surgery.
干预措施: Gastric Ultrasound (Diagnostic Test)
Liberal Feeding Protocol
Patients will be fed enterally up until call to OR at which time their stomachs will be decompressed with a pre-existing gastric tube.
干预措施: Gastric Ultrasound (Diagnostic Test)
结局指标
主要结局
Gastric Residual Volumes
时间窗: Within one hour of operative intervention.
Quantification of gastric residual volumes as measured in milliliters using antral cross-sectional areas and semi-quantitative gastric volumes using standardized grading scores.
次要结局
- Peri-operative aspiration events(Within four months of study completion, 16 months from study start)
- Estimation of the amount of enteral nutrition lost prior to surgery using the different NPO protocols(Zero to sixteen hours prior to surgery)
- Comparison of two different NPO protocol populations(Within four months of study completion, 16 months from study start)
