Severe anaphylactic shock without exanthema in a case of unknown latex allergy and review of the literature.
We describe a case of severe anaphylactic shock without exanthema in an 8-year-old boy who was undergoing elective surgery for an ileostomy. The boy had a history of four anorectal operations in the newborn period, but no history of allergies. Sudden, profound bronchospasm and cardiorespiratory collapse occurred 30 min after the beginning of the operation. No signs of exanthema or urticaria were seen. The patient was resuscitated successfully and remained ventilated for 25 h. During this time, he needed epinephrine in dosages of 0.3-0.05 microg.kg-1.min-1. Radioallergosorbent (RAST) tests for the patient were positive Cap Class 3 and 4, and specific immunoglobulin E was highly positive, suggesting a natural rubber latex allergy as the cause of the anaphylactic shock. Ethylene oxide was negative. Eleven days later, a further operation was performed with a strict latex-free protocol in the presence of histamine 1 and 2 receptor antagonists. On this occasion, the intraoperative course was uneventful. Incidence of anaphylactic reactions, prevalence of latex sensitization, special risk groups and management are discussed.
