Evaluation of Mannitol as Oral Contrast media in CT Abdomen Examinations

This is analytic study was carried out in Almoualem Hospital and and Asia Hospital in computed tomography departments in period from April to June 2018, contains 33 males and 27 females. The problem of study was to evaluate negative of oral contrast media (mannitol) in detecting of bowel pathology that wasn't more carried out on researchs . The main goal of the study is to obtainment good CT abdomen can been diagnosable on bowel pathologys and bowel wall problems . The study was done by CT machine of Toshiba 128 slice for negative oral media of 36 patients after fasting at lest 6hours and GE healthcare 64slice for positive oral media of 24 patients after prepared by castor oil and disflatyl tabs and fasting. The data collected by data sheet which contain ,age ,gender , amount of oral contrast ,patient complications ,lumen appearance and bowel wall appearance and time of oral intake . and analyzed by SSPS. The result revealed that participants who responded positive contrast oral media was poor, while for the majority of who responded nagative contrast oral media were excellent (55%) or good (40%). Lumen appearance does not depend on media bowel wall appearance depends on media. Bowel distension depend on time but not depending on type of oral contrast used and type of oral must be used determined by patient pathology related to. The bowel wall gradually disappears as time of oral intake increases. 71.7% of participants didn't complain, and 28.3%of them had diarrhea as complication .Study found that mannitol is more cheaper and more available than omnipaque. Study recommend that when pathology related to bowel wall or the exam is CTA the perfect choice is negative oral media ,also larger sample should be used in further studies .
