Abstract:

Objective To investigate the effect of low-fiber enteral nutrients on intestinal cleanliness, blood glucose and comfort level of diabetic patients during bowel preparation of time-restricted feeding less than 24 hours. Methods Totally 108 diabetic inpatients underwent colonoscopy were randomly divided into two groups: the control group (n=55), the observation group (n=53). In the dinner on day-0 of microscopic examination, the control group was managed semi-fluid low-fiber food, and low-fiber enteral nutrients in the observation group. The calorie volume of the two groups was same, which calculated from the nutrition department according to the height and weight of these patients. The Ottawa Bowel Preparation scale (oBPs) was employed to assess effects of intestinal cleanliness, from the beginning to end of endoscopic examinationthe, the key observation was blood glucose value, largest amplitude of glycemic excursion (LAGE), the incidence of hypoglycemia and comfort level in the two groups.Results The better intestinal cleanliness was found in the observation group (P<0.05). Except for day-0 17:00 and day-1 13:00 of the microscopic examination, the control group had lower blood glucose values on other time points (P<0.05), and lower incidence of hypoglycemia was detected in the observation group (χ²=3.89, P<0.05), LAGE was lower in the observation group vs the control group (P<0.01); in the comfort level, the observation group indicated higher the satisfaction (P<0.05), with the reduction of defecation frequency and anal pain (P<0.01). Conclusion During bowel preparation, low-fiber enteral nutrients can improve intestinal cleanliness and comfort level, better than semi-liquid low-fiber food, which has merit to reduce blood glucose fluctuations and incidence of hypoglycemia for diabetic patients.
