Filter by:A. Determine if Respiratory Volume Monitor (RVM) can be used during procedural sedation to adequately monitor patient's respiratory status as compared to capnograph Aims B. Compare the time of capture of respiratory events (depression, arrest, etc…) on both the RVM and the capnograph C. Compare the incidence of missing or poor quality readings between the RVM and the capnograph D. Compare RR readings between the RVM and the capnograph (during periods with adequate data quality on both devices) E. If RMV can identify respiratory obstruction. Capnography
The objective of this study is to compare the safety, tolerance and efficacy of BLI800 to a PEG based preparation prior to colonoscopy in adolescent patients.
This is a phase II, two-part, multiple-dose, dose-finding, single-blind study in adult participants undergoing elective colonoscopy for screening or diagnostic purposes. This study is designed to test various ABP-700 infusion regimens for rational selection of one or more dosage regimen(s) to be used for future clinical development of ABP-700 in procedural sedation.
This study assesses the benefits of continuous intravenous lidocaine administration during sedation for colonoscopy. Sedation will consist of propofol infusion titrated to provide adequate working conditions to the gastroenterologist. Patients will be randomly allocated into two groups: lidocaine infusion (bolus of 1.5 mg/kg followed by a continuous infusion of 4 mg/kg/h) or the same volume of placebo (normal saline)
This prospective, randomize, controlled trial will compared cap-assisted water exchange with water exchange in patients undergoing sedated colonoscopy. Investigators test the hypothesis that that cap-assisted water exchange is more efficient and causes a shorter insertion time.
About 30% of patients were reported to suffer inadequate bowel preparation.
The purpose of this study is to compare the effect of physician education about evidence based practices for colonoscopy alone, versus physician education plus a multi-component staff implementation strategy to improve adequacy of bowel preparation. Additionally the investigators will examine implementation factors that influence adoption of the evidence based practices.
This study is an open, prospective, comparative diagnostic studies aimed at improving the colonoscopy results, by optimizing the way of preparation for endoscopy
In France, nearly 1.3 million colonoscopies are performed each year. Colonoscopy is the gold standard in France for colorectal cancer screening in populations at risk. However, it has a number of limitations. The quality of the bowel preparation is a critical step for the successful completion of this examination. The occurrence of interval cancers raises the problem of missed lesions. A literature review showed that there were differences between the endoscopy units on quality standards for bowel preparation. The rate of unprepared colonoscopy is estimated between 20 to 40% . In a recent cohort study, 28% of 2516 colonoscopies had a score of Boston of less than or equal to 6. These colonoscopies generate substantial additional costs to redo colonoscopies, estimated at 35 million euros in 2008. The establishment a predictive score for quality of bowel preparation based on a self-administered questionnaire completed by patients during the pre-colonoscopy consultation, would help identify patients at risk of poor preparation in order to optimize the prescribed preparation in this consultation.
Better patient education prior to colonoscopy improves adherence to instructions for bowel preparation and leads to cleaner colons. The hypothesis of this trial is that computer assisted instruction (CAI) using video and 3D animations can maximize the effectiveness of nurse counselling and consequently improves bowel cleanliness. Furthermore, CAI will positively influence the patient experience. Adults referred for colonoscopy were included in a Dutch large volume endoscopy unit. Exclusion criteria were illiteracy in Dutch and audiovisual handicaps. Patients were prospectively divided into two groups, one receiving nurse counselling and one receiving CAI and a nurse contact before colonoscopy. The main outcome, cleanliness of the colon during examination, was measured with the Ottawa Bowel Preparation Scale (OBPS) and the Boston Bowel Preparation Scale (BBPS). Patient comfort and anxiety were assessed at multiple time points: directly after the instruction and one hour before colonoscopy. Comfort was rescored 2 hours after colonoscopy. We also tested knowledge and comprehension one hour before colonoscopy. Statistical analyses included Mann-Whitney.
