THE SAFETY OF I.V. IODINATED LOW OSMOLAR CONTRAST MEDIUM IN PATIENTS WITH PENICILLIN ALLERGY IN CT SCAN EXAMINATIONS
Keywords:Iodinated LOCM, penicillin allergy, CT scan
AbstractBackground: Intravenous (I.V.) low osmolar contrast media (LOCM) is commonly used during computerized tomography CT scan examinations, especially in diagnosis and staging of tumours, trauma and abdominal examinations. Many radiologists are relactant to do enhanced examination if patients had history of penicillin allergy. This study aims to evaluate the incidence of LOCM-related side-effects in patients with penicillin allergy compared to patients without penicillin allergy. Methods and patients: Prospective study of 357 patients examined in CT scan unit in Al-Yarmouk teaching hospital, 44 of them had history of penicillin allergy, all given i.v. contrast medium (LOCM), and the prevalence of LOCM related side effects calculated for both groups. Results: The prevalence of contrast medium related side effect was 0.64% in patients without history of penicillin allergy, while of the 44 patients with penicillin allergy, no side effects has been encountered. Conclusion: No significant increase in LOCM related side effect was seen in patients with penicillin allergy.
