Blenderized Tube Feedings for Adult Patients on Home Enteral Nutrition: A Pilot Study.

OBJECTIVE: Despite surveys indicating a high prevalence of blenderized tube feeding (BTF) as an alternative to commercial enteral nutrition (EN), there remains a paucity of data regarding use in clinical practice. The objective of the present open-label pilot study was to assess the safety and effectiveness of BTF in adult patients being given home enteral nutrition (HEN). DESIGN: This is an open-label pilot study, in which all participants who had been on traditional EN formulas were changed to BTF for 6 weeks. SETTING/LOCATION: The Mayo Clinic in Rochester, Minnesota. PARTICIPANTS: Twenty individuals gave their consent to participate in the study, with nine completing the 6-week BTF protocol. OUTCOME MEASURES: Weight was measured at baseline and at 6 weeks of BTF use. Participants completed a survey regarding the frequency of BTF use and adverse effects, at baseline and then weekly for 6 weeks. RESULTS: Nine participants with a mean age of 60.6 ± 7.8 years completed the 6-week protocol. BTF use increased from 4.85 ± 2.44 to 6.45 ± 0.82 days per week from week 1 to week 6. The percentage of participants consuming >50% of their calorie intake from BTF increased from 23.1% (3 of 13 participants) at week 1 to 44.4% (4 of 9 participants) at week 6. Six of nine participants experienced weight gain, weight was maintained by one participant, and two participants lost weight (intentionally in one and due to an intolerance of commercial formula in the other). CONCLUSIONS: BTF was found to be safe and effective in promoting weight gain in adult participants who required HEN for at least 6 weeks.

Gravity Flow in Proposed Enteral Tube Small-Bore Connectors.

BACKGROUND: Enteral nutrition (EN) misconnections have been identified as a serious and potential deadly problem. An international effort led by EN industry leaders has developed a small-bore enteral connector (ENFit) that in theory will reduce the frequency of misconnections. Despite the potential benefit of preventing misconnections, the full impact of adoption of the ENFit connector is unknown. To assess the impact of transitioning to ENFit on our home EN (HEN) patients, the current study evaluated gravity feeding comparing 2 proposed small-bore connectors to the legacy (current connector) using various commercial formulas. METHODS: Six commonly used enteral formulas in our facility with varying density and viscosity were tested in triplicate. Forty milliliters of formula was poured into a syringe connected to an ENFit or legacy (current) feeding connector attached to varying French size tubes. The time it took formula to flow through the connectors was recorded, and the test was repeated in triplicate. RESULTS: All formulas took significantly longer to flow through the first ENFit connector compared with the legacy connector ( P < .05). The second ENFit connector demonstrated similar flow dynamics to the legacy connector. CONCLUSIONS: There is wide variability in the flow dynamics in ENFit connectors with significant potential impact on many facets of HEN, including medicine delivery, blenderized feeds, venting, and compliance with EN due to increased time to administer feeds. We highly recommend additional testing of flow dynamics, including gravity flow, as ENFit tubes are being developed and adopted.
