![]() Gastroparesis causing increased gastric residual volume, gastroesophageal reflux, abdominal pain and distension, diarrhea, vomiting, risk of bronchoaspiration and ventilator-associated pneumonia are common complications to critically ill patients. However, studies indicate that an early nutritional therapy often does not occur and there is often a failure to supply adequate calories and proteins to meet the patient's needs Gastrointestinal intolerance to EN can be a difficulty attributed to this inadequacy. Adequate nutritional support is associated with a reduction in morbidity and mortality rates and with the improvement of the clinical outcome of these patients. Keywords: gastric motility, gastric residual volume, intensive care unit, enteral nutrition AbbreviationsĮnteral nutrition (EN) is the main route of feeding for patients in the Intensive Care Unit (ICU). Other factors are likely more determinant for gastric emptying and assessment of enteral nutrition tolerance. The results indicate that the increase of the enteral nutrition infusion rate did not positively affect the GRV of critically ill patients. ![]() We found a significant negative correlation (r=-0.46 p=0.02) between the increase in IR and GRV. Most patients (52%) did not reach 80% of the protein-calorie recommendations within 72 hours from the beginning of the enteral nutrition. The GRV, before and after the increase in IR, presented the medians 10 and 23, respectively. The mean age for the sample was 63☑5years, with a higher prevalence for male sex (56%). The GRVs were collected from records of the Clinical Nutrition Unit, as well as the increase in IR and nutritional adequacy. The study was conducted with 25 male and female patients, older than 18years old, who were hospitalized in the Intensive Care Unit (ICU) with exclusive enteral nutrition for at least 72hours. The aim of this work was to evaluate the GRV measurements of in critically ill patients and its linking with an increase in the infusion rate (IR) of enteral nutrition. Gastric residual volume (GRV) is routinely measured in critical care patients. However, gastrointestinal complications pose a challenge to an appropriate nutritional supply. In critically ill patients, enteral nutrition is considered the main method of nutritional support. ![]()
