Evaluation of One-day Polyethylene Glycol Powder Solution for Colonoscopy in Children

The purpose of this study is to examine the effects of current standard of care Polyethylene Gylcol powder (PEG-P)colonoscopy preparation on a patient's serum electrolytes, tolerance of the prep, and how well the bowel is cleansed. The primary aim is to determine the proportion of patients with clinically significant serum electrolyte abnormalities at the time of colonoscopy and how well the prep is tolerated. Secondary objectives include: 1) how well the bowel is cleansed with this preparation, and 2) to determine the most effective way to communicate instructions about the bowel preparation with the child and family.
