Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
