基于风燥虚辨治咳嗽变异性哮喘之思路探析
Analysis of the Idea of Treating Cough Variant Asthma Based on “Feng Zao Xu”

咳嗽变异性哮喘(CVA)是导致慢性咳嗽的三大病因之一，临床常表现为反复性、刺激性的干咳及呛咳。中医对此类疾病虽有一定章法和治疗经验，但在从致病因素的角度辨治CVA这一思路上仍待补充和完善。笔者认为，风、燥、虚作为三种致病因素始终贯穿于CVA整个病程中，CVA患者先天禀赋多有不足，风邪为CVA发病之先导，而燥邪推动了疾病的发展，风燥久伏、伤阴耗气、损及脾肾则致疾病迁延难愈。针对CVA的中医治疗，应重在祛风解痉，宣利肺气，同时养阴润肺、调理脾肾。在预防上要做到顾护正气、防风、避寒、抗过敏，使过有效的防治避免CVA进展为典型的哮喘，达到彻底根治的目的。
Cough variant asthma (CVA) is one of the three major causes of chronic cough in China, and is often clinically manifested as recurrent, irritating dry cough and choking. Although TCM has certain rules and treatment experience for such diseases, it still needs to be supplemented and improved in the idea of identifying and treating CVA from the perspective of pathogenic factors. The author believes that Feng, Zao and Xu as the three pathogenic factors have always run through the entire course of CVA, CVA patients have many innate endowments that are insufficient, Feng is the precursor of CVA disease, and Zao promotes the development of the disease, Feng and Zao for a long time, injury to yin and gas consumption, damage to the spleen and kidneys cause the disease to prolong and difficult to heal. Traditional Chinese medicine treatment for CVA should focus on dispelling wind and spasmodic, promoting lung qi, nourishing yin and moisturizing the lungs, and regulating the spleen and kidneys. In terms of prevention, it is necessary to take care of healthy qi, wind protection, cold avoidance, and anti-allergy, so that CVA can be prevented from progressing into typical asthma through effective prevention and treatment, and the purpose of radical cure can be achieved.
