Abstract
Background: Administration of early enteral feeding in critically ill patients was shown to improve outcome. However achieving target calorie and protein is found to be sub optimal in a proportion of critically ill patients. Fixed rate feeding and frequent feed interruptions for interventions are a major contributing factor for suboptimal energy and protein delivery. However volume based feeding in which target volume delivered over a given time with adjustable infusion rate is recommended by American Society of Enteral and Parenteral Nutrition. In this study we tried to find out the success rate of volume based feeding.
Methods: This was a prospective observational study. Proportion of feed days in which more than 80 % feed volume achieved was the primary objective and proportion of feed days in which more than 80 % calorie and protein achieved was the secondary objective. A volume based feeding protocol was implemented in the unit. Patients were followed up until they were transferred out from intensive care unit or until tube feeding stopped. Daily feed volume, calorie and protein achieved were audited.
Results: More than 80% prescribed volume, calorie and protein were delivered in 95%, 85.7% and 56.12% of enteral nutrition days respectively. In 98.7% of enteral nutrition days volume based feed is tolerated without any adverse events.
Conclusions: Volume based feed is safe and with prompt training of staff in delivering volume feeds, adequate nutrition can be delivered for patients in case of any interruption of feed.
Keywords: calorie, enteral nutrition, feed protocol, protein, volume based feeds.
