Latex allergy

Individuals with repaired OA/TOF are at increased risk of latex allergy. This is similar to all patient groups with multiple surgeries and medical procedures in childhood, such as spina bifida, where these bring about repeated exposure to latex. In one study, 25% were positive on prick testing and 13% symptomatic. Risk of allergy increases with increased number of procedures, longer stay in hospital and length of time the patient had a central venous catheter in. (141,142)
