The correlation between patient satiety sensation and total gastric fluid volume: a prospective observational study
Authors' conclusion
This study suggests that the correlation between total gastric fluid volume and satiety sensation is very weak. Satiety did not reliably predict total gastric fluid volume.

- Population
- Fasted elective surgical patientsexam inconclusive in 14
- Participants

- Outcome
- Correlation between hunger (0-10 NRS) and total gastric fluid volume measured with gastric ultrasonography
