This research proposal aims to investigate the correlation between a) the hunger feeling as measured by a ten point scale and b) total gastric fluid volumes and content as measured with gastric PoCUS in fasted, healthy subjects \> 18 of age, scheduled for elective surgery.
An ultrasound exam will be performed before induction of anaesthesia. GUS results from selected patients will be systematically acquired and assessed following an algorithm (Appendix Ia). The ultrasound results will be collected on a standardized form (Appendix IIa). The technique is performed in the supine and right lateral decubitus position (Appendix Ib) and only by anesthesiologists with sufficient experience with ultrasound and the technique. The patient will be asked to indicate his/her satiety on a predetermined ten-point scale. Patient data and satiety score will be collected on a standardized form (Appendix IIb). The scanning anaesthesiologist is blinded to the result of the questionnaire.

the correlation between total gastric fluid volume in millilitres and a ten-point (0-10) satiety scale.
total gastric fluid volumes are measured with gastric point-of-care ultrasound, satiety is measured with a 0 to 10 scale. Zero stands for no satiety ( very hungry, thirsty), ten stands for fully satisfied ( no hunger or thirst).
Time frame: Before surgery
the correlation between the Perlas grading scale ( 0,1,2) and a ten-point (0-10) satiety scale.
the Perlas grading scale is a semi-quantitative scale where 0 stands for no fluid appreciated in the gastric antrum with gastric ultrasound in both the supine and right lateral decubitus postion (RLD), grade 1 stands for fluid appreciated in the RLD only, grade 2 stands for fluid appreciated in both the supine and RLD position. This will be correlated to the abovementioned satiety scale.
Time frame: Before surgery
the correlation between the type of gastric content ( no content, fluid content, solid content) and a ten-point (0-10) satiety scale
gastric ultrasound will reveal whether the stomach is empty, contains fluid or solid content. This will be correlated to the abovementioned satiety scale.
Time frame: before surgery
