Gastric Residual Volume During Enteral Nutrition in ICU Patients: The REGANE Study

摘要: To compare the effects of increasing limit for gastric residual volume (GRV) in adequacy enteral nutrition. Frequency gastrointestinal complications and outcome variables were secondary goals. An open, prospective, randomized study. Twenty-eight intensive care units Spain. Three hundred twenty-nine intubated mechanically ventilated adult patients with nutrition (EN). EN was administered by nasogastric tube. A protocol management EN-related used. Patients to be included a control (GRV = 200 ml) or study group (GRV = 500 ml). Diet ratio (diet received/diet prescribed), incidence complications, ICU-acquired pneumonia, days on mechanical ventilation ICU length stay variables. Gastrointestinal higher (63.6 vs. 47.8%, P = 0.004), but only difference frequency high GRV (42.4 26.8%, P = 0.003). The diet during 1st week (84.48 88.20%) (P = 0.0002). Volume similar both groups weeks 3 4. Duration ventilation, pneumonia similar. treated is not affected GRV. 500 ml associated adverse value can equally recommended as normal
