【摘要】 文章遵“卫出三焦”理论探析了感染后咳嗽的病机及诊治思路。肺气闭郁，卫失布散而使表邪流连，是感染后咳嗽迁延不愈的核心病机；同时，卫气根源于先天肾气，受后天水谷滋养，所以中焦脾胃、下焦元气受损均能影响卫气的生成、运行及输布，进而导致肺、卫功能障碍，表邪不去而咳嗽不休。诊断宜四诊合参以辨三焦虚损，治疗以宣发上焦肺、卫为主，如荆防败毒散合止嗽散加减；或健运中焦，如二术二陈汤合参苏饮加减；或温养下焦，如麻黄附子细辛汤合理中汤加减，选方用药皆应以辨证为准。后附验案一则。更多还原

【Abstract】 The pathogenesis, diagnosis and treatment of post-infectious cough were analyzed according to the theory of “Defensive Qi out of Sanjiao”. Lung Qi blocked, Defensive Qi can’t scattered and make the exterior pathogen linger, is the core pathogenesis of post-infectious cough. At the same time, the root of Defensive Qi originates from the innate Kidney Qi and is nourished by the acquired water and grain, so the dysfunction of Spleen and Stomach in the Middle Jiao, and the Lower Jiao Qi hurts both can affect the generation, operation and distribution of Defensive Qi, and then lead to the dysfunction of Lung Qi and Defensive Qi, and cough endlessly while the pathogen does not go away. The diagnosis should be combined use of the four diagnostic methods to distinguish the deficiency of Sanjiao, and the treatment should be based on dispersing Lung Qi and Defensive Qi in upper Jiao, such as Jingfangbaidu powder combined with Zhisou powder. Or drive Medium Jiao, such as Erzhu Erchen decoction combined with Shen Su Yin. Or warm Lower Jiao, such as Mahuang Fuzi Xixin decoction combined with Lizhong decoction, prescription and medication should be based on syndrome differentiation. And a case is attached.更多还原
