Learning Objective #1: The learner will be able to identy the relationship between bolus feeding intervention and the effectiveness of prevented pulmonary aspiration
Learning Objective #2: assess the pulmonary aspiration index during bolus feeding


This randomized, controlled study employed two feeding protocols for 107 participants in two intensive care unit (ICU)s of a medical center to investigate the efficacy of intermittent nasogastric (NG) feeding in preventing aspiration pneumonia in critically ill patients on ventilators. 

The participants were randomly assigned to receive continuous (51 patients) or intermittent (56 patients) feeding.  The primary outcomes, including gastric emptiness index and pulmonary aspiration index, were examined on Day 0 and Day 7 of the intervention.  In addition, patients were followed up to the 21st day to evaluate the secondary outcomes, which included length of stay (LOS) in the ICU and airway status. 
The results showed that the patients in the intermittent feeding group had a higher total intake volume at Day 7 (p= .000), had been extubated earlier at Day 21 (p= .002), and had a lower risk of aspiration pneumonia (odds ratios: .146, 95% CI .062 -.413, p= .000) than the patients in the control group.  However, there was no significant difference between the two groups’ LOS. 
The results of this study provide evidence that clinical caregivers may use to make better decisions in terms of feeding methods for critically ill patients.
