简要总结
Patients who are scheduled by their health care provider for routine computed tomography (CT) scan will be asked to participate in this study. The primary purpose is to determine if there is a difference in patient preference for Omnipaque versus Gastroview as oral contrast for abdominal pelvic CT. A secondary objective is to evaluate if there is significant difference in bowel opacification for the two agents.
详细描述
Participants must be scheduled for a CT scan prior to enrollment in this study. Informed consent will be obtained from patients acceptable to be included in the study. It will be noted if there is a history of gastrointestinal surgery and if the patient is nauseated before the contrast is administered.
Patients will be randomized to receive either a standardized dilution of Gastroview or Omnipaque orally. The two agents will be prepared to have nearly equivalent iodine concentration. No flavoring agent (ie Crystal Light) will be added. The plan is to mix the agents per manufacturer recommendation as follows:
Omnipaque 350 26cc in 974 cc of water (9.0g iodine) Gastroview 25cc in 1000cc of water (9.17g iodine)
The time the patients start and stop consuming the contrast as well as the volume taken and time from first drink to start of the scan will be recorded by a blinded investigator. Patients will be asked to drink 900cc. Technical staff will report any side effects or complications observed.
After completion of the CT scan, patients will fill in a survey rating the taste of the agent on a 5 point scale, and will be asked to report any side effects. Planned rating scale is as follows:
