Chlorhexidine今日在手術房逐漸被廣泛用作抗菌劑及消毒液。對chlorhexidine過敏是很少的,而因chlorhexidine用作皮膚消毒液,所引起過敏的案例更是少見。一名53歲的男性病人,於三次不同的泌尿科手術中,分別接受全身麻醉、半身麻醉以及靜脈麻醉,發生三次原因不明的休克現象。這位病人手術部位的皮膚是用Chlorhexidine消毒液消毒的。後來病人血清中chlorhexidine的特異IgE呈現陽性反應,同時也排除了其他可疑的藥物及藥劑。我們必須知道chlorhexidine是可以引起過敏的,即使只是用在皮膚消毒,本文的探討是可以減低病人對藥物副作用的風險。
Chlorhexidine is an antiseptics and disinfectant for operating rooms. Anaphylaxis to chlorhexidine is rare, and anaphylaxis to chlorhexidine due to skin application is even rarer. A 53-year-old male patient had three unexplained anaphylactic shock episodes during three consecutive, individual, urological operations under general anesthesia, spinal anesthesia and intravenous general anesthesia, respectively. Chlorhexidine was used as a skin disinfectant for this patient. Later, serum chlorhexidine specific IgE revealed positive result, with suspected drugs and chemicals ruled out. Health care workers should be aware of a potential allergen property of chlorhexidine even when applied on skin.
