Filter by:This study was designed to assess the safety and efficacy of AQUAVAN® Injection in providing adequate sedation in patients undergoing colonoscopy. Prior to the procedure, patients received fentanyl citrate for pain management followed five minutes later by AQUAVAN® Injection for sedation. Throughout the procedure, study personnel assessed the patient's vital signs and depth of sedation. After the procedure, the patient, physician, and an evaluator were asked to complete satisfaction surveys.
To evaluate the efficacy of standard HalfLYTELY® as a bowel cleansing preparation for adult patients undergoing virtual colonoscopy (VC).
The purpose of the this study was to compare the safety and efficacy of HalfLytely (2L NULYTELY + 20mg bisacodyl) to NULYTELY for preparation prior to colonoscopy.
The objective of this study is to determine the efficacy and safety of HalfLytely as compared to Visicol as bowel preparations before colonoscopic examination.
The quality of colon cleansing has a major impact on efficiency and cost of colonoscopy. A hand-out was made to instruct and motivate patients to adequately clean the bowel before colonoscopy. The aim of the study is to compare adequacy of bowel cleansing in hospitalized patients receiving the hand-out or not on the day before colonoscopy.
Colorectal cancer (CRC) is the leading cause of cancer death not only in the Western countries but also in Taiwan. Colonoscopy is now gradually accepted as one of the powerful tool for colorectal cancer screening. Not only for survey after positive fecal test, it is also applied as primary screening modality for CRC screening.Colon cleansing before colonoscopy thus becomes critically important and inadequate preparation may lead to low diagnostic yield with missed lesions, increased risk of complication and prolonged procedure time. Though the importance of good colon preparation can not be over-emphasized, diet control before colonoscopy and ingestion of large amount of lavage solution remain a significant hurdle to overcome and investigators continue to seek for the ideal colon preparation with respect to quality and examinee satisfaction. After the introduction of polyethylene glycol electrolyte lavage solution (PEG-ELS) for bowel preparation before colon procedures, its safety was well documented and the efficacy of colon cleansing was proven efficient. The timing of ingesting PEG-ELS is different between institutes and some ingest PEG-ELS as a whole at the night before colonoscopic examination and some ingested in split-dose manner which ingest half of the solution at previous night and remaining on the day of examination. Some institutes ask examinee to receive lavage solution on the day of examination. The manufacturer advices start taking medication on the day before the investigation according to their printed instruction on the package of PEG-ELS. Though there were a lot of studies that conducted to describe the result of colon cleansing in different fashion, the result is still controversial. This prospective, randomized, single-blinded trail evaluated and compared the efficacy of colon preparation at two timing of colon preparation, namely, in previous night or on the day of colonoscopic examination. In this study, we enrolled those who have already colon neoplasia detected during voluntary routine health check-up and received second colonoscopic examination for either elective polypectomy or endoscopic mucosectomy (EMR). We used not only the cleansing condition as a reference of adequate preparation; we also compared the diagnostic yield of lesion number as an objective comparator between these two methods.
The primary aim of the study is to increase the success rate of cecal intubation in first colonoscopy and in repeated colonoscopy for the first failed procedure. The secondary aims are to assess the procedure time, the terminal ileum intubation rate, the endoscopist satisfaction score, the patients' acceptance, the complication rate of these two procedures, and the intravenous sedative drugs used.
Very often, patients receive sedative medication before a diagnostic, therapeutic, or surgical procedure to help them relax, keep them calm, and to relieve them from pain. This is called procedural sedation. During procedural (mild to moderate) sedation, a patient is first given a pain-relief medication (analgesic) and then a medication to help him/her relax and keep him/her calm (sedative). Propofol is the drug commonly used for sedation because it releases immediately into the blood stream and causes fast sedation. AQUAVAN (fospropofol disodium) is made as a slow release version of propofol, allowing for fast sedation and possibly faster recovery and discharge. This study is intended to compare several different doses of AQUAVAN in patients having a colonoscopy in order to find the right dose that will get patients to a level of mild to moderate (procedural) sedation.
