[Anesthesiologic pecularities in patients with latex allergy]

Immediate-type hypersensitivity due to natural rubber (latex) products is an increasing problem for the anaesthetist, because a major part of products used for anaesthesia contains natural rubber. If the patient has a positive history of allergic symptoms after contact to natural rubber like urticaria, bronchospasm or anaphylaxis, preoperative skin tests, in vitro tests, and if necessary even the latex-glove-wearing test should be performed. If preoperative diagnosis of natural latex allergy is established, latex free anaesthesia is strictly recommended; otherwise life-threatening complications may ensue. Accordingly, we report on a patient who developed intraoperative anaphylactic shock following exposure to natural latex. In addition to the treatment with drugs, latex-containing products should be immediately replaced by latex-free ones, in particular all persons should put on latex-free gloves. For prevention of anaphylactic episodes in sensitized patients the reader is provided with an exemplary list of latex-free products for anaesthesia. Because the incidence of immediate-type reactions to latex is still increasing, intraoperative occurrence of an anaphylactic reaction to an unknown agent is likely to be due to allergy to natural rubber.
