Dose response of PEG 3350 for the treatment of childhood fecal impaction☆,☆☆
Section snippets
Design
The study was designed to test the efficacy and safety of 4 different doses of PEG 3350 in the treatment of fecal impaction in children. The design was a prospective, double-blind, parallel study. Patients enrolled were children examined in the pediatric gastroenterology clinic with complaints of chronic constipation and/or soiling and who had a fecal impaction. The primary outcome measure of the study was clearance of fecal impaction. Presence or absence of fecal impaction was assessed by
Results
Forty-one children fulfilled the inclusion criteria; 40 children (27 male, median age 7.5, range 3.3-13.1 years) completed the study. One child receiving a dose of 1.5 g/kg per day did not show up at the follow-up visit. Overflow fecal soiling occurred in 35 children, with 91% having it daily. Associated symptoms included straining (90%), hard consistency stools (85%), feeling of incomplete evacuation (55%), feeling of blockage (40%), and defecation only achieved using manual maneuvers such as
Discussion
In this prospective, double-blind, parallel study we found that children with fecal impaction can be treated effectively and safely with PEG 3350. Doses of 1.0 and 1.5 g/kg per day for 3 days were more effective than lower doses, regardless of age of patients, duration of symptoms, or severity of constipation. The effective doses can be administered in relatively small daily volumes.
The use of PEG-ELS–based solutions has become increasingly popular in the treatment of childhood constipation.3, 4
