Experimental: Extremely Thick - Mildly Thick - Extremely Thick - Mildly Thick Participants will receive 4 weeks Extremely Thick, 4 weeks Mildly Thick, 4 weeks Extremely Thick and 4 weeks Mildly Thick blenderized tube feeds. The volume, caloric density and frequency will be matched to pre-study feeding regimen. |
Other: Extremely thick blenderized tube feed
Commercial blenderized tube feed, not diluted
Other: Mildly thick blenderized tube feed
Commercial blenderized tube feed, diluted with ingredients contained in blend

Outcome Measures
Primary Outcome Measures
- Upper GI symptoms [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
differences in daily parental rating of upper gastrointestinal symptoms from the validated Gastroparesis Cardinal Symptom Index-Daily Diary (GCSI-DD) between extremely and mildly thick blenderized tube feeds
Secondary Outcome Measures
- Gastrointestinal symptoms [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
Pediatric Quality of Life Inventory (PedsQL) Gastrointestinal Symptoms Questionnaire, scale of 0 to 100, higher scores indicate less symptom burden
- Gastrointestinal symptoms [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
Pediatric Quality of Life Inventory Gastroparesis Questionnaire, , scale of 0 to 100, higher scores indicate less symptom burden
- Pulmonary symptoms [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
Pediatric Cough Questionnaire, score ranges from 0 to 25, higher scores indicate less symptom burden
- Health care utilization [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
frequency of hospital admissions
- Health care utilization [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
length of hospital admissions
- Health care utilization [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
rates of ER/urgent care visits
- GI medication use [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
% of participants requiring acid suppressive medication or GI motility agents such as cyproheptadine and erythromycin
- Height [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
height
- Weight [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
Weight or weight for length
- Weight for height/body mass index (BMI) [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
weight for height (children < 2) or BMI (over 2 years of age)
- number of patients with unplanned G-tube exchange [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
- urine output adequacy [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
frequency of urine output
- rate of respiratory suctioning per day [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
how often suctioning is required (e.g. number of times per day)
- need for antibiotics for pneumonitis [8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design)]
frequency of antibiotics prescribed for pulmonary indications
