过敏性休克是一种危及生命的速发性全身变态反应,常表现为上呼吸道梗阻,严重呼吸困难、低血压、循环衰竭等一系列危重的症状。起病较缓、症状较轻的病例,可以自行缓解,或经治疗而控制。起病过急、症状严重而又持续不解的病例,往往虽经紧急抢救,注射肾上腺素、抗组织胺类药物及肾上腺皮质激素等药物仍然难免于死亡。因此如何提高抢救的效果,特别是怎样预防过敏性休克发生的问题,在今天仍然是临床急救的重要课题。
Anaphylactic shock is a life-threatening generalized systemic allergic reaction, often manifested as a series of critical symptoms of upper respiratory tract obstruction, severe dyspnea, hypotension, circulatory failure. Moderate onset, mild symptoms, can relieve itself, or by treatment and control. Urgency onset, severe symptoms and continuing puzzled cases, often through emergency rescue, injection of epinephrine, antihistamines and adrenal hormones and other drugs are still inevitable death. Therefore, how to improve the effectiveness of emergency treatment, especially how to prevent the occurrence of anaphylactic shock, is still an important issue for clinical emergency.
