USEFULNESS OF SERUM ELECTROLYTE EXAMINATION AFTER MECHANICAL BOWEL PREPARATION.

Background and objectives: Quality of colonic preparation is a crucial part for accuracy and safety of colonoscopy that should be effective, safe, and well- tolerated by patients. Polyethylene glycol (PEG) and sodium phosphate (NaP) solutions are the most regularly used preparation and might lead to adverse events. There was no consensus about usefulness of serum electrolyte examination after bowel preparation. Aim of this study to determine the usefulness of serum electrolyte examination after bowel preparation. Methods: From July 2017 to December 2017, patients who underwent mechanical bowel preparation for elective colonoscopy were enrolled. Patient demographic data and serum electrolyte levels were recorded and evaluated. Results: 100 patients were included in this study. Of these, 15 patients had hypokalemia after bowel preparation. 14 patients developed mild hypokalemia and only 1 patient developed moderate hypokalemia. There were no adverse event during the operation and no significant risk factors were identified on multivariate analysis. Conclusions: In patients who undergo elective colonoscopy, are given the appropriate bowel preparation agent the changing of the serum electrolyte level after bowel preparation are mild and not clinically significant. Routine testing for serum electrolyte after bowel preparation seem to not necessary in these patient. [ABSTRACT FROM AUTHOR]
