GRV measurement form
vomiting, abdominal distention
‘FI’ represents a combination of clinical signs that suggest that an individual cannot tolerate enteral feeding. The most comprehensive definition is presented below: It is the inability to digest more than 50% of enteral feeding presented as GRV, abdominal distention or vomiting, or both of them, and thus disruption of the patient’s feeding plan [An OG or nasogastric (NG) tube suitable for the week of gestation was inserted at the time of hospitalization. In the current research, preterm infants were fed by the intermittent feeding method every 3 h; the feeding time was 30 min with a pump. GRV was checked in infants with abdominal distention or vomiting before the previous feeding (measuring the gastric content after feeding and resting using an injector), and residuals >50% and/or bloody residues were considered FI.
