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

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. 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). Draw the ROC curve to get the best cut-off value. This study comprises 150 patients. The mean age was (58.63±16.45) yr., the average APACHE Ⅱ score was 17.43±6.99. The incidence of FI for three days (72 h-FI%) was 28.0%. The multivariate analysis demonstrated that the Day 2 CSA-right lateral decubitus (RLD) was an independent risk factor for FI-day 2 ( =0.033), Day 3 CSA -RLD was an independent risk factor for FI-day 3 ( =0.016). Patients with day 3 CSA-RLD ≥7.092 cm had significantly higher rates of FI ( =0.001). Gastric antrum cross-sect
