Problems related to the use of the iode contrast product: challenges and prospects in mali

Introduction: Medical imaging is based on the study of tissue contrasts related to the physical processes used and the physico-chemical nature of the tissues. To increase and/or confirm the information provided by the image, the administration of contrast products was imposed on users. The aim of the work was to harmonize the use of iodine contrast products in the various medical imaging services in Mali. Methodology: the study took place in the radiology department of the Medical Clinic Marie Curie in Bamako, Mali and at the Dermatological University Hospital Center in Bamako. There were 11 health centers in Mali subject to a semi-direct interview during the 3-month period on the use of iodine contrast product supplemented by data from the literature. Results: In our study, the most used iodinated contrast product was omnipaque with a rate of 46%. The administration of the doses of contrast products usually used was 300 or 350 mg/ml of iodine. Omnipaque dosed at 300 or 350mg/ml of iodine accounted for 28% of cases. The use of the quantity of doses of contrast product administered was 1ml/kg, the most used with 55% of cases. The quantity used in thoracic CT angiography for the search for pulmonary embolism was 100ml with a rate of 28% of the majority of cases. Injections with the automatic injector and by hand were the most common injection methods with a rate of 82% of cases and 18% of cases had used the automatic injector alone. The complications related to the injection of contrast product intravenously manually or by automatic injector recorded during our study were extravasation with a rate of 46%. Conclusion: Our study made it possible to identify the quantity of contrast product and the dosage used per patient per health center and complications related to their use. We must prohibit the standardization of the doses used before any examination with harmonization of the use of these PDCs through discussion sessions and educational tools.
