Exploring the pathogenesis and clinical thinking of coronavirus disease 2019 based on “toxin impairing pulmonary collaterals”/ 从“毒损肺络”探究新型冠状病毒肺炎的病机及诊疗思路

Based on the characteristics of the pathogenesis and clinical manifestations, location of COVID-19 is mainly in the pulmonary collaterals, and the core pathogenesis is “toxin impairing pulmonary collaterals” Treatments of dispelling damp toxin, clearing away heat toxin and resolving stasis toxin should be applied as early as possible to clear the lung The methods of aromatic resuscitation and clearing collaterals should be used in severe and critical periods Pay enough attention to open-close treatments on the depletion syndromes, resolving blood stasis to clear collaterals During the convalescence, tonifying and activating the pulmonary collaterals, clearing away residual pathogens should be used Based on “removing toxicity and dredging channels”, differentiation treatments of comprehensive syndromes could effectively relieve clinical symptoms, prevent progression and improve prognosis
