抗感染中心静脉导管致过敏性休克2例

2 cases of anaphylactic shock caused by antiseptic impregnated central venous catheter

中心静脉置管技术成熟,多应用于术后营养支持、内科化疗等方面。目前国内医院多采用抗感染中心静脉导管,因导管内外含氯己定涂层,可显著降低导管相关性感染的发生,但极少数患者存在对氯已定过敏。本文报道置管后发生过敏性休克患者2例,表现为短时间内出现血压下降、意识障碍或皮肤瘙痒及荨麻疹等,分析考虑为氯已定涂层致过敏性休克,经积极抢救治疗后症状消失。说明在置管工作中充分了解患者过敏史及熟练过敏性休克抢救流程尤为重要。
