Study Arms (2)

OSS group

EXPERIMENTAL

Bowel preparation for colonoscopy was performed using oral sulfate solution as laxative

Drug: Oral sulfate solution (OSS)

Polyethylene glycol group

ACTIVE COMPARATOR

Bowel preparation for colonoscopy was performed using polyethylene glycol as laxative

Drug: Polyethylene Glycol Electrolyte

Interventions

OSS contained 17.5 g sodium sulfate, 3.13 g potassium sulfate, 1.6 g magnesium sulfate, and flavoring agents in an aqueous liquid form supplied in a 177 mL bottle. Take 177ml sodium, potassium and magnesium sulfates oral solution (diluted to 480ml) within 30 minutes 14-16 hours before colonoscopy, followed by two doses of 480ml warm water within 1 hour; Repeat the procedure 3-4 hours before colonoscopy.

OSS group

Take 1000 ml polyethylene glycol electrolyte solution within 1 hour at 8 p.m. the day before colonoscopy; take 2000 ml polyethylene glycol electrolyte solution within 2 hour 4-6 hours before colonoscopy.

Polyethylene glycol group

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Voluntarily participate and sign informed consent;
  • Scheduling screening, surveillance, and diagnostic colonoscopy;

  • Subjects with serious cardiac and cerebrovascular diseases, bronchial and lung diseases, suffering from metabolic disease or endocrine disease, abnormal blood clotting mechanism, malignant tumor, electrolyte abnormalities, epilepsy, Renal or liver dysfunction;
  • Subjects with confirmed or suspected gastrointestinal obstruction, gastric retention, gastroparesis, gastric emptying disorder or acute gastrointestinal bleeding;
  • Subjects with acute severe colitis (such as active severe inflammatory bowel disease, acute bacterial dysentery, diverticulitis, etc.);
  • Subjects with a history of major gastrointestinal surgery (e.g. gastric bypass, gastric septal surgery, colostomy, colectomy, etc.);
  • Subjects with constipation or suspected severe gastric motility disorder;
  • Women with positive pregnancy tests or pregnancy plans, and women in lactation;
  • Subjects who have participated in any other clinical trials within the last 3 months;
