In a child with spina bifida undergoing cardiac catheterization, which allergy should be considered in addition to an iodine allergy?

In the case of a child with spina bifida who is undergoing cardiac catheterization, an important consideration is the potential reaction to latex. Spina bifida is often associated with an increased incidence of latex allergy due to frequent medical interventions, such as surgeries and catheterizations, during the child’s early life. The immune system can become sensitized to latex proteins through repeated exposure, leading to allergic reactions in some individuals.

During cardiac catheterization, various medical devices such as catheters and gloves may contain latex. Thus, it's crucial to inquire about and account for a latex allergy before proceeding with any procedure involving these materials. This will help prevent possible allergic reactions that could complicate the procedure and pose a risk to the child's health.

In contrast, while other allergens like iodine, penicillin, soy, or dairy may be relevant in specific scenarios, they do not have the same strong association with spina bifida. Iodine allergies would be a consideration because of the contrast material used in imaging, but in the context of spina bifida, the risk of latex allergy is a primary concern due to the reasons mentioned.
