A 65-year-old man had bypass surgery 10 years previously with pulmonary artery catheter monitoring. Shortness of breath and mitral regurgitation necessitated repeat left and right heart catheterization using a pulmonary artery catheter. Before any iodinated contrast media exposure, the pulmonary artery catheter was inserted and within 2 min the patient developed anaphylaxis associated ventricular fibrillation. It was discovered that the pulmonary artery catheter used in the cath lab had a latex balloon and that the patient had been exposed to latex 10 years ago. Latex induced anaphylaxis is rarely considered in the differential diagnosis of patients with hypersensitivity reactions in the cath lab, intensive care unit, and operating room. The principal reason for failure to recognize the latex balloon as a potential allergen is that most health professionals are not aware that almost all pulmonary artery catheters contain a latex balloon. The risk of an allergic response to latex is 0.8% for the general population. Others at high risk include those who have had multiple surgical procedures and interventions with repeated latex exposure. Five to 10% of all U.S. health professionals and those performing household duties wearing latex gloves have an allergic response to latex. Latex hypersensitivity is an IgE dependent reaction, while iodinating contrast medium reaction is an IgE independent reaction. If latex hypersensitivity is suggested by pre-procedural history or if the patient falls into a high-risk group, pre-procedural skin testing and/or latex IgE radioallergosorbent (RAST) should be performed.(ABSTRACT TRUNCATED AT 250 WORDS)
