Continuous pump-tube enteric hyperalimentation

R P Dobbie, J A Hoffmeister

    Surgery, Gynecology & Obstetrics
    |August 1, 1976
    PubMed
    Summary

    Continuous pump-tube feeding via small caliber tubes into the small intestine offers superior enteral nutrition. This method effectively utilizes the gastrointestinal tract for patients unable to eat, improving nitrogen balance.

    Area of Science:

    • Gastroenterology
    • Nutritional Science

    Background:

    • The enteric route for alimentation is often underutilized, despite the benefits of using an intact gastrointestinal tract in patients unable to eat.
    • Traditional methods like bolus tube feeding with large bore gastric tubes are less effective than newer approaches.

    Observation:

    • A novel small-caliber feeding tube allows easy insertion and precise positioning in the distal duodenum or proximal jejunum.
    • This method demonstrates excellent patient tolerance and requires a suitable infusion pump for successful implementation.

    Findings:

    • Continuous pump-tube feeding into the small intestine is superior to older methods.
    • Elemental diets are not necessary for routine enteral nutrition and can be costly and difficult to tolerate.
    • Isocal, an isotonic, lactose-free liquid diet, effectively supports pump-tube feeding, converting negative to positive nitrogen balance at >30 kcal/kg body weight.

    Implications:

    • This technique optimizes enteral nutrition delivery, enhancing patient recovery and nutritional status.
    • It provides a more effective and potentially cost-efficient alternative to elemental diets for long-term nutritional support.
    • Highlights the importance of leveraging the functional gastrointestinal tract for patient alimentation.
