Comparison of the Effects of Different Gastric Residual Volume Thresholds for Holding Enteral Feeding on Nutritional Intake in Critically Ill Patients in Internal Medicine
Comparison of the Effects of Different Gastric Residual Volume Thresholds for Holding Enteral Feeding on Nutritional Intake in Critically Ill Patients in Internal Medicine
This is a randomized control trial with a parallel design. Eligible patients will be randomly assigned into two groups: a control group which will be holding tube feeding when the GRV reaches 200 mL, and an experimental group will hold tube feeding when the GRV reaches 300 mL. Enteral feeding will be administered according to the study flow chart.
Background: Malnutrition is a common issue among critically ill patients. which increases hospital stays, costs, and mortality rate. According to the study, the primary reason for nurses to hold enteral nutrition is elevated gastric residual volume (GRV). However, there is still no consensus on the definition of high residual gastric volume, there is currently no consensus among experts and scholars regarding the threshold for holding enteral nutrition. Clinical nurses may prematurely hold enteral nutrition due to concerns regarding potential side effects such as vomiting and choking. The aim of this study is to increase the threshold for holding enteral feeding based on the results of the study, in order to improve nutritional intake in critically ill patients in internal medicine.
Objective: Increase the nutritional intake of critically ill patients in the Department of Internal Medicine by increasing the threshold for holding tube feeding.
Methods: This is a randomized control trial with a parallel design. Eligible patients will be randomly assigned into two groups: a control group which will be holding tube feeding when the GRV reaches 200 mL, and an experimental group will hold tube feeding when the GRV reaches 300 mL. Enteral feeding will be administered according to the study flow chart. The outcome data will collected based on the medical chart including frequency of diet volume ratio (diet received/diet prescribed), incidence of gastrointestinal complications, ventilator days, Ventilator-associated pneumonia, length of intensive care unit(ICU) stay, changes in nutritional indicators, APACHE Ⅱ and Duration of parenteral nutrition use.
Expected result: The results of this study will provide evidence regarding the improved effectiveness and safety of increasing the threshold of GRV in medical ICU and inform future evidence-based practice.
