Prevention and treatment principles of different types of iodine contrast agents / 中国基层医药

ABSTRACT

Objective To explore the prevention and treatment principles of different types of iodine contrast agents.Methods 240 patients with CT enhancement were divided into two groups according to the contrast agent type 80 patients with ionic contrast agent (control group), 160 cases with non-ionic contrast agent (observation group).The allergic reaction was evaluated according to the ADR classification.The constituent ratio of the allergic reaction was observed in the two groups.The contrast ratio of the hypersensitive reaction was observed.The clinical manifestations of the allergic reaction were observed.Results In the control group, there were 8 cases of mild allergic patients,7 cases of mild allergic patients in the observation group,7 cases of moderate allergic patients in the control group,6 cases of moderate allergic patients in the observation group,4 cases of severe allergic patients.There were 2 cases of severe allergic patients in the observation group.In the observation group, there were 15 cases of total allergies and 19 cases of total allergies in the control group.The number of allergies in the observation group was lower than that in the control group (x2=9.063,P<0.05).80 cases of contrast agent induced 19 cases of allergic reaction;non-ionic contrast agent iodopromide 79 cases, induced 9 cases of allergic reactions;non-ionic contrast agent iodohydrin contrast 81 cases.Allergy symptoms such as skin rash, malaise, chills and fever, eyelid edema, throat discomfort and voice, such as nausea and vomiting, dizziness, chest tightness, cardiovascular symptoms such as shock, blood pressure changes and so on.Conclusion Non-ionic iodine contrast agent is superior to ionic contrast agent in the incidence of allergic reaction.However, it is an important measure to reduce the patients' injury caused by different types of hypersensitivity reaction.It is worth the attention of clinicians.
