During registration of the cardio-tocogram, a 40-year old Para I Gravi
da II developed a contact urticaria against the rubber tape for fixati
on of the transducer. A latex allergy was proved by skin test and a po
sitive radio-allergo-sorbens test (RAST). The Caesarean section, which
was mandatory due to ophthalmological problems, was performed unevent
fully using latex-free products. Risk factors for latex allergy are at
opia like pollinosis, neurodermitis, asthma bronchiale of allergic ori
gin, and further repeated exposition to latex products.
