Failed or Difficult Intubation clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Water Method in Patients With Incomplete Colonoscopy

Start date: November 2011
Phase: N/A
Study type: Interventional

Water method with water exchange has been shown to reduce medication requirement and pain experienced during colonoscopy. It increases the success rate of cecal intubation in sedated and unsedated patients undergoing screening colonoscopy. Exchange of water during scope insertion minimizes distension of the colonic lumen and decreases loop formation. Exclusion of air from the colon during insertion by omission of air insufflations and suction removal of residual air prevent elongation of the colon. These maneuvers facilitate colonoscopy insertion in average patients and may enhance the success of difficult colonoscopy. Colonoscopy has been considered the gold standard procedure in screening for colorectal disease. However, 5-10% of colonoscopies are incomplete due to patient discomfort, difficult anatomy and prior abdominal or pelvic surgery. The investigators postulate that these patients may benefit from using the water method for colonoscopy. In this proposal the investigators test the hypothesis that compared with conventional air insufflations the water method with water exchange significantly enhances the success rate of cecal intubation in patients with immediately failed colonoscopy. The aim of the study is to compare the outcome of colonoscopy using the water method versus the conventional air method in patients with incomplete colonoscopy. The primary outcome is cecal intubation success rate. The secondary outcomes include cecal intubation time, maximum pain score during colonoscopy, overall pain score after colonoscopy and adenoma detection rate.
