Primary outcomePrimary: Aspiration Risk Grade — 30; 30; 20; 9 Participants
Summary
The primary objective of this study is to evaluate gastric volume and contents as well as gall bladder size in patients scheduled for routine, urgent, and emergency surgery. The hypothesis is that patients with stress, pain and opioid administration will have delayed gastric emptying and therefore a larger gastric fluid volume than those scheduled for elective surgery. The patients who have an appropriate NPO time will have a larger gallbladder size than the patients with shorter NPO time.
