Effects of oral sodium phosphate solution, as a colon preparation agent, on the serum potassium level in patients undergoing colonoscopy at a Secondary Care Community Hospital

Background Colonoscopy is the gold standard investigation for assessing of the intra-luminal colorectal pathology. Effective bowel preparation contributed efficient visualizing of the colon. Osmotic laxatives such as sodium phosphate (NaP) are commonly used for colonic preparation for colonoscopy. A meta-analysis suggested that NaP offered a more effective and more readily completed preparation than PEG-based regimes. However, the use of sodium phosphate solution has been shown to significantly reduce the serum potassium level which is likely to affect cardiac rhythm in particular by prolonging the QT interval. But this affect was not clinically meaningful in most of patients. Sodium phosphate (NaP) are commonly used for colonic preparation for colonoscopy in Phukieo Rural Hospital a secondary care community hospital, the effect of oral sodium phosphate solution, as a colon preparation agent, on the serum potassium level in patients undergoing colonoscopy was evaluated. นพินธต์น้ฉบบั
