Clinical Trial Summary

It is currently recommended to start enteral nutrition early in intensive care unit children receiving invasive or non-invasive mechanical ventilation. 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). Residual gastric volume (RGV) measurement had been recommended to monitor the tolerance to enteral nutrition in mechanically ventilated patients receiving early enteral feeding. 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. 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. 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. Ultrasound examination of the antrum could therefore constitute an alternative to gastric suctioning for the monitoring of RGV in intensive care unit patients. This prospective study aims to assess the reliability of the RGV monitoring based on gastric suctioning compared to ultrasound technique. Secondary endpoint is to assess whether increased gastric volume, aspirated or calculated by ultrasound, is an independent risk factor of regurgitation and / or vomiting.

Intervention

Other:
• Gastric ultrasound
A first gastric ultrasound will be performed in the supine and the right lateral (RLD) decubitus position, allowing a qualitative analysis of the gastric contents (empty, liquid, solid, solid-liquid). The antral area will also be measured in both positions. The volume of gastric fluid content will be calculated according to the following formula: volume (ml) = -7,8 + (0,035 x antral area in RLD (mm²)) + 0,127 x age (month). This examination will be immediately followed by the aspiration of gastric contents through the nasogastric tube used for enteral feeding, into 50-ml syringes, by a nurse blinded to the result of the first ultrasound examination. A second antral ultrasound examination will then be performed, by the same investigator blinded to the volume aspirated. The occurrence of regurgitation and / or vomiting occurring within the 12 hours before and after the examination will be recorded.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of patients with an empty stomach after aspiration of gastric contents performed for the residual gastric volume monitoring.	Empty stomach is defined as the lack of any gastric content when performing the second gastric ultrasound, after aspiration of gastric contents.	Maximum 1 day (Second gastric ultrasound, performed once aspiration of gastric contents has been achieved)
