What this study is about

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.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Treatments and study arms

Gastric Point of Care Ultrasound

Procedure

After the patient has undergone intubation, the patient will be positioned in the supine and then the right lateral decubitus position on the operating room table. A curvilinear ultrasound probe with gel will be placed on the patient below the xiphoid process. A picture is then obtained of the antrum of the stomach. The probe may need to be moved, tilted, or rotated to obtain the clearest image of the antrum of the stomach. After the images are obtained, the patient will be repositioned to supine for the procedure. Once the surgical procedure is complete, the patient will once again undergo gastric POCUS prior to extubation.

Primary outcomes

Change in distance from peritoneal wallend of the individual's procedure, at 2 hrs after procedure start on postoperative day 0

Range: 3-5 cm. Higher score indicates greater displacement and less utility of gastric point-of-care ultrasound in these patients.

Gastric antrum Cross-sectional area (CSA)end of the individual's procedure, at 2 hrs after procedure start

Range: 1-10 centimeters squared. Gastric antrum Cross-sectional area (CSA) is a calculated product of Anteroposterior (AP) Diameter and Craniocaudal (CC) diameter. (CSA = AP x CC) Higher score means that patient has a larger gastric volume and is at a higher aspiration risk.
