Study on the Safety and Efficacy of Sodium Phosphate Powder for Intestinal Preparation in People Aged 50 to 70 Years Old

After admission, the patient underwent comprehensive renal function and electrolyte tests. The first medication was taken at 7pm the day before the examination. One bag of sodium phosphate powder was diluted with 800ml or more of warm and cool water before taking. The second dose of medication should be taken at 7am on the day of operation or examination (or at least 3 hours before the examination), with the same usage as the first dose, with a 12 hour interval between each dose. The standard dose for each dose is 1 bag, until clear water like stool appears.

After admission, the patient underwent comprehensive renal function and electrolyte examination. The evening before the intestinal examination, 2000ml of polyethylene glycol electrolyte San III isotonic solution was taken, 250ml every 10-15 minutes, and it was taken within 2 hours. On the day of examination, 2000ml of polyethylene glycol electrolyte San III isotonic solution was taken 3-4 hours in advance until clear water like stool appeared.
