The case of a 42-year-old latex-sensitive female who experienced urticaria, pruritus, soft tissue swelling, and significant hypotension during an outpatient barium enema is described. These signs and symptoms of anaphylaxis occurred immediately after enema tip insertion and before infusion of contrast material. The patient responded well to appropriate emergency therapy and her symptoms resolved in a 24-hour period. Subsequent radioallergosorbent test showed an elevated immunoglobulin E (IgE) level to latex, and the skin prick test produced significant induration and erythema in response to latex. This patient experienced an IgE-mediated anaphylactic reaction to the latex enema tip. Emergency physicians need to be aware of the spectrum of latex-induced allergic reactions.
本文描述了一名42岁对乳胶敏感的女性病例，该患者在门诊进行钡灌肠时出现荨麻疹、瘙痒、软组织肿胀和严重低血压。这些过敏反应的体征和症状在灌肠头插入后立即出现，且在注入造影剂之前。患者对适当的紧急治疗反应良好，症状在24小时内得到缓解。随后的放射变应原吸附试验显示，其针对乳胶的免疫球蛋白E（IgE）水平升高，皮肤点刺试验对乳胶产生了明显的硬结和红斑。该患者对乳胶灌肠头发生了IgE介导的过敏反应。急诊医生需要了解乳胶引起的过敏反应的范围。
