Gastric residual volume is the amount aspirated from the stomach following administration of enteral feed. An aspirated amount of ≤ 500ml 6 hourly is safe and indicates that the GIT is functioning
Checking gastric residual volumes (GRV) always seems to be a topic of debate. When should we check the residual and when does the GRV prompt the need for interventions? Is this an opportunity to educate staff or to reevaluate the patient’s enteral nutrition regimen? What are GRV?
An overview of critical care guidelines for enteral nutrition (EN) and the use of gastric residual volume (GRV) management and monitoring as an essential component of EN patient care to help prevent complications.
Checking a gastric residual volume in enterally fed patients to protect against aspira-tion pneumonia has become routine practice to the point of habit.
Gastric residual volume (GRV) measurement to detect gastrointestinal (GI) dysfunction is a common diagnostic procedures in critical care, albeit still not well standardized being operator-, patient-, and tube-dependent.
Purpose of review: Gastric residual volumes (GRVs) remain a major deterrent to adequately feeding patients with gastric-delivered enteral nutrition. The purpose of this review was to define the most up-to-date consensus of the utility of the use of GRVs for monitoring tube-feeding intolerance in gastric-fed patients.
Develop protocols that call for proper flushing before and after medication administration, during continuous feedings, before and after intermittent feedings, and before and after gastric residual volume (GRV) measurements.
Consequently, monitoring of gastric residual volume (GRV), that is, to measure GRV periodically and modulate the speed of enteral feeding according to GRV, has been recommended as a management goal in many intensive care units.
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. Measured volumes were categorized into 3 overlapping groups: at least 150 mL, at least 200 mL, and at least 250 mL.
High gastric residual volumes (GRV) or the volume of food or fluid remaining in the stomach at a point in time during enteral tube nutrition feeding, increase the risk for pulmonary aspiration (the most severe complication of tube feedings).
