![]() The incidence of vomiting and VAP, GRV, length of mechanical ventilation and ICU stay, APACHE II and SOFA scores, and mortality rate were noted. GRV was measured every three hours, and gastric intolerance was defined as GRV>250 cc. Methods: This descriptive study was carried out on 150 adult patients admitted to the intensive care unit over a 14-month period, from October 2015 to January 2017. In this trial, the effect of GRV on the frequency of VAP was evaluated in critically ill patients under mechanical ventilation. Objectives: The value of gastric residual volume (GRV) monitoring in ventilator-associated pneumonia (VAP) has frequently been questioned in the past years. Although aspiration occurs without high gastric residual volumes, it occurs significantly more often when volumes are high. No consistent relationship was found between aspiration and gastric residual volumes. However, the frequent aspirators had a significantly greater frequency of 2 or more volumes of at least 200 mL and 1 or more volumes of at least 250 mL. ![]() Volumes less than 150 mL were common in both aspiration groups. Eighty-nine patients were frequent aspirators. Large-bore tubes identified most of the high volumes. Gastric residual volumes were compared between the 2 aspiration groups.Īpproximately 39% of the 206 patients had 1 or more gastric residual volumes of at least 150 mL, 27% had 1 or more volumes of at least 200 mL, and 17% had 1 or more volumes of at least 250 mL. Patients were categorized as frequent aspirators if 40% or more of their tracheal secretions were positive for pepsin and as infrequent aspirators if less than 40% of their secretions were positive for pepsin. Measured volumes were categorized into 3 overlapping groups: at least 150 mL, at least 200 mL, and at least 250 mL. In a prospective study of 206 critically ill patients receiving gastric tube feedings for 3 consecutive days, gastric residual volumes were measured with 60-mL syringes every 4 hours. ![]() To describe the association between gastric residual volumes and aspiration of gastric contents. The helpfulness of bedside assessment of gastric residual volume in the prediction of aspiration has been questioned, as has the volume that signals increased risk of aspiration.
