This prospective study aims to assess the reliability of the RGV monitoring based on gastric suctioning compared to ultrasound technique. Regarding some controversies and lack of information on the effect of body position on this issue, the current study was conducted. Ultrasound examination of the antrum could therefore constitute an alternative to gastric suctioning for the monitoring of RGV in intensive care unit patients. Gastric residual volume represents the status of food tolerate. Gastric ultrasonography is a non-invasive and easy-to-use tool allowing accurate preoperative assessment of gastric contents, based on both qualitative examination of the gastric antrum and calculation of gastric content volume. This lack of relationship between RGV monitored using gastric suctioning and the occurrence of regurgitation, aspiration and pneumonia may reflect the inaccuracy of the aspiration method used for the measurement of the RGV, as it has been reported in adult patients. Nevertheless, several studies have challenged the usefulness of such RGV monitoring, showing that it led to reduced caloric intake without any benefits in terms of reducing the occurrence of vomiting and the incidence of VAP. residual volume with associated gastric enzymes and hydrochloric acid should be returned to the stomach when gastric residual volume measures under 150. Residual gastric volume (RGV) measurement had been recommended to monitor the tolerance to enteral nutrition in mechanically ventilated patients receiving early enteral feeding. Gastrointestinal intolerance is the main complication related to early enteral feeding in intensive care unit patients, characterized by gastroparesis with delayed gastric emptying that may lead to regurgitations, vomiting, pulmonary aspiration, and potentially increased risk of ventilator-associated pneumonia (VAP). It is currently recommended to start enteral nutrition early in intensive care unit children receiving invasive or non-invasive mechanical ventilation. It then became common practice in ICUs to identify early feeding intolerance. In one study, 21 of standard fasted patients had gastric volume >1.5 ml kg 1. The practice of checking GRV originated to reduce the risk of aspiration pneumonia. Why Should I Register and Submit Results? Although more patients in the liberal group had gastric fluid volumes >1.5 ml kg 1, this is reasonably in line with previous studies that measured gastric fluid volumes in standard fasted adults: 36 of patients had volumes >1.5 ml kg 1.
