摘要 随着对支气管哮喘发病机制研究的进展,特别是支气管镜对呼吸道组织活检、病理、病理生理、细胞生物学科对哮喘基础研究所取得的成果,使我们对其认识得到不断修正、提高,随其治疗亦在不断修正完善中.40年代前仅认识到哮喘有平滑肌痉挛,因此治疗就是解痉.当支气管平滑肌发生痉挛,临床上表现有喘息时,就给予解痉药物,经典的有麻黄素、氨茶碱及β2受体激动剂.痉挛缓解或解除,治疗就终止,再次出现症状时,再次给予解痉药物.为什么会反复痉挛呢?纤支镜对呼吸道黏膜活检等研究,发现反复出现痉挛的物质基础是呼吸道存在慢性炎症,是其导致呼吸道高反应(BHR).当接触到多种危险因素时,呼吸道平滑肌就发生痉挛,以减少有害物质进入呼吸道,此时就发生气流受限,呼吸道阻塞,临床则出现喘息.
