Gastric Ultrasound in Patients Who Have Undergone Bariatric Surgery

This is a nonrandomized prospective study. The purpose is to describe how to image the stomachs of patients after the patients have had bariatric surgery. Participants will have the stomachs imaged while undergoing general anesthesia for a bariatric procedure pre-operatively and post-operatively using point-of-care ultrasound (POCUS). The pre-operative imaging will be done post-intubation and the post-operative imaging will be done pre-extubation. There are minimal risks to gastric POCUS. Risks typically include discomfort to the patient, which will be avoided as the patient will be under general anesthesia at the time of imaging.
