Cold-induced urticaria is an unusual systemic disorder that develops in response to exposures to cold temperatures in susceptible individuals. Patients with cold urticaria are potentially at risk of severe systemic anaphylactic shock-like reactions. This disorder is of unique clinical importance in cardiac surgery, considering the use of cardiopulmonary bypass and hypothermia. Contact of blood with hypothermia and subsequent warming can be associated with hemodynamic instability, hypotension, and cardiovascular collapse, mainly during the period of rewarming. We report the case of a 41-year-old woman with chronic cold-induced urticaria, who underwent a successful coronary bypass grafting, and describe perioperative management of this rare disorder.
冷诱导荨麻疹是一种不常见的全身性疾病，易患人群在接触寒冷温度后会发生这种疾病。患有冷荨麻疹的患者有发生严重全身性过敏样休克反应的风险。在心脏手术中，这种疾病具有独特的临床重要性，因为心脏手术会使用体外循环和低温。血液与低温接触，随后复温可导致血液动力学不稳定、低血压和心血管衰竭，主要发生在复温期间。我们报告了一例 41 岁患有慢性冷诱导荨麻疹的女性患者成功进行了冠状动脉旁路移植术，并描述了这种罕见疾病的围手术期管理。
