Bedside ultrasonic localization of the nasogastric tube in a patient with severe COVID-19: A case report.

Background: The indwelling nasogastric tube is commonly used for supplying enteral nutrition to patients who are unable to feed themselves, and accurate positioning is essential in the indwelling nasogastric tube in the body of the aforementioned patients. In clinical practice, abdominal radiography, auscultation, and clinical determination of the pH of the gastric juice are routinely used by medical personnel to determine the position of the tube; however, those treatments have proved limitations in specific cases. There are few case reports on the precise positioning of the nasogastric tube in patients with coronavirus disease 2019 (COVID-19), for whom a supply of necessary nutrition support is significant throughout the process of treatment.
