Brief Summary

Emerging studies have evaluated POCUS (Point of Care Ultrasound) for assessing of gastric content prior to anesthesia to reduce the risk of aspiration and demonstrated that POCUS can accurately identify presence of gastric food or fluid. Despite accumulating studies evaluating POCUS as a diagnostic modality to evaluate for gastric food content prior to anesthesia, there is no study to date that has evaluated the role of POCUS prior to endoscopy among patients with upper GI bleeding. Therefore, this study is to evaluate the diagnostic accuracy of POCUS for retained gastric content prior to endoscopy among patient hospitalized/admitted with upper GI bleeding. This study would take place at Loma Linda University Medical Center. Subjects will be any one who has upper GI bleed required EGD and age of greater than 18 years old. The study will plan for 1 year or reach 50 patients (whichever one comes first). In addition, subjects will be recruited from ED, ICU, Medicine ward by the PI, SubPI, and Collaborators. Subject will received ultrasound up to 6 hours prior the start of endoscopy. The location of Ultrasound would either take place at GI lab prior to scope or at the ward prior to transportation to GI lab or at ICU prior to endoscopy. The ultrasound would focus upper abdomen area and look for antrum. the result will be immediately read before endoscopy and fill out on the sheet before the endoscopy. Patient then proceed with endoscopy. At the end of the scope, the researcher will ask the endoscopist questions regarding how well they could see each part of the stomach in order to complete the study. Both results are compared between US and Endoscopy. Endoscopist is blinded in this study.

Upper GI Bleeding; Point of Care Ultrasound; Upper Endoscopy; Gastric Content; GI Bleed

Outcome Measures

Primary Outcomes (1)

• measurement is gastric food content/blood.

  Ultrasound would be conducted on upper abdomen to evaluate the presence of blood and/or food in the stomach. The result would divided into empty (no food), small and large. ultrasound mainly evaluate the antrum area to see whether it is dilated/distended or not. if it is collapsed, then it is considered empty. If it is largely dilated, it would be considered large.

  after obtaining informed consent and prior to endoscopy being conducted.

• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Age \>18 admitted with upper GI bleeding defined by symptoms of hematemesis, melena, and/or hematochezia accompanied by hemodynamic changes (pulse \>100/min and/or systolic blood pressure \<100/min) scheduled for upper endoscopy.

You may qualify if:

• Age \>18
• patient presents with hematemesis
• and/or melena
• and/or hematochezia accompanied by hemodynamic changes (pulse \>100/min and/or systolic blood pressure \<100/min)
• Patient is scheduled for upper endoscopy due to the above.

You may not qualify if:

• Decline consent for study
• Patients with last solid meal \<6 hours and clear liquids \<2 hours prior to the endoscopy
• Prior surgery in the stomach
• Patient has duodenum, Ileus, or bowel obstruction
• patient has history of gastric cancer
