Abstract

NUNES, Gonçalo et al. Nutritional deficiency during colonoscopy preparation: the forgotten iatrogeny. Rev. esp. enferm. dig. [online]. 2018, vol.110, n.5, pp.285-291. ISSN 1130-0108.  http://dx.doi.org/10.17235/reed.2018.5140/2017.

Background and aims:

bowel preparation for colonoscopy induces a semi-fasting state, with a potential negative impact on fragile patients. The present study aims to quantify nutritional deficiency during colonoscopy preparation.

Methods:

this was an observational and cross-sectional study. A convenience sample was obtained that included adults that underwent colonoscopy after bowel preparation with Klean-Prep(r) according to the center protocol. Anthropometric evaluation was performed and nutritional deficiency was calculated via the quantification of energy and protein intake during the 48 hours prior to the examination which was compared with the individuals' needs. The association between nutritional deficiency with the quality of bowel preparation, age and status (hospitalized/ambulatory) was evaluated.

Results:

the study included 131 patients aged 21-91 years (mean 63.6 ± 13.2 years); 73 cases were male. Malnutrition reached 67.2% using specific anthropometric tools. A median preparation quality of six points was found when the Boston Bowel Preparation Scale was considered. The mean intake 48 hours prior to the procedure was 1,795 kcal and 100 g of protein. A daily energy intake of less than 50% of the individual needs was observed in 88 patients and less than 25% in 29 cases. The mean energy and protein deficiency were 59% (p < 0.01) and 45% (p < 0.01), and there was no correlation with preparation quality (p > 0.05). Nutritional deficiency is similar in hospitalized and ambulatory patients (p > 0.05), but higher in older individuals (p = 0.04).

Conclusions:

nutritional deficiency during colonoscopy preparation was significant, more so in older patients, and there was no correlation with the quality of bowel preparation. We conclude that bowel preparation regimens should be reformulated with an improved nutritional intake and the inclusion of nutritional supplements without residues.
