Bouvet L, Zieleskiewicz L, Loubradou E, et al. - For the evaluation of residual gastric volume, the reliability of aspiration via a nasogastric tube was compared with ultrasound in this study performed on 61 adult patients on mechanical ventilation, receiving continuous enteral feeding via a nasogastric tube for > 48 h. A total of 60 (98%) patients had a qualitatively evaluated full stomach at first ultrasound test as compared with 52 (85%) following gastric suctioning. Researchers found a significant reduction in the calculated gastric volume after gastric suctioning, with no significant reduction noted in the number of patients with volume ≥ 250 ml. Within the last 24 h, vomiting occurred in four of the nine patients with calculated gastric volume ≥ 250 ml. They noted a significant reduction in the antral cross-sectional area between the third and the fourth ultrasound examination. Findings revealed the non-reliability of gastric suctioning as a tool to monitor residual gastric volume, as well as the feasibility and promising utility of gastric ultrasound as a tool for gastric volume monitoring in clinical practice.
