Protocol for treatment of constipation with polyethylene glycol 3350 plus electrolytes in critically ill children

Introduction and objectives: No studies have analysed the effectiveness of treatment for constipation in critically ill children. The aim of this study was to assess the implementation, efficacy and safety of a treatment protocol using polyethylene glycol 3350 with electrolytes (PEG 3350+E) for constipation in critically ill children. Methods: We conducted a single-centre prospective study in children admitted to the paediatric intensive care unit for a minimum of 72 h and who developed constipation. Children with previous gastrointestinal disorders or diseases were excluded. The patients were treated with rectal enemas or with the oral PEG 3350+E protocol at the discretion of the treating physician. We compared clinical and demographic variables as well as adverse events (diarrhoea, abdominal distension and electrolyte imbalances). Results: The sample included 56 patients with a mean age of 48.2 +/- 11.9 months, of who 55.4% were male. Forty-four patients (78.6%) were treated with PEG 3350+E and 12 (21.4%) with rectal enemas. The proportion of patients who responded well to treatment was greater in the PEG 3350+E group (79.5%) compared to the enema group (58.3%), but the difference was not statistically significant (P=.151). There were no significant differences between the groups in any of the adverse effects. Treatment with PEG 3350+E was more effective in children aged less than 2 years (100%) compared to older children (100% vs. 65.4%; P<.01), with no significant differences in the development of adverse events. Conclusions: The PEG 3350+E treatment protocol for constipation in critically ill children was effective and associated with few adverse events, even in children aged less than 2 years.(c) 2023 Asociacion Espanola de Pediatria Published by Elsevier Espana, S.L.U.
