Tube feeding or enteral feeding is an artificial method of delivery of nutrients to the stomach or small intestine by especially designed feeding tubes. It is indicated when oral intake is not possible or desirable or is insufficient to meet the nutritional requirements (Table 17.1). Tube feeding is considered superior to parenteral nutrition in terms of reduced infection rate, duration of hospital stay, and ventilator dependence . Sepsis and multi-organ failure may develop due to the failure of gut barrier [1–3]. A functional or partially functional gastrointestinal tract is a prerequisite for tube feeding.
