[The Value of Gastric Antrum Cross-sectional Area Mearsured by Bedside Ultrasound Predicted Feeding Intolerance in Critically Ill Patients].

Objective: To explore the feasibility and effectiveness of gastric antrum cross-sectional area (CSA) mearsured by bedside ultrasound for predicting early feeding intolerance (FI) in critically ill patients.

Methods: The data were extracted from a multicenter prospective observation study between February 2018 to December 2018. A bivariate logistic regression model was established to identify the correlation between the gastric antrum cross-sectional area (CSA) and the feeding intolerance (FI).
