Treatment of CRF With Syndrome Differentiation of TCM
January 5, 2021 updated by: Henan University of Traditional Chinese Medicine
An Exploratory Clinical Study on Reducing AECOPD of Chronic Respiratory Failure With COPD by Syndrome Differentiation
Taking the patients with chronic respiratory failure caused by COPD as the research object and the acute exacerbation of COPD as the main outcome index, the investigators hope to establish the syndrome differentiation and treatment scheme of COPD treated by traditional Chinese medicine, reduce the acute exacerbation of AECOPD, improve the clinical symptoms, improve the quality of life, reduce the mortality, preliminarily explore the mechanism of action, and lay the foundation for further research.

Detailed Description
Chronic respiratory failure of chronic obstructive pulmonary disease belongs to the category of "lung distention", "asthma syndrome", "dyspnea" and "phlegm drink" in traditional Chinese medicine.
According to traditional Chinese medicine, the pathology of this disease is mainly the dysfunction of lung ventilation.
The basic pathogenesis is that the viscera are repeatedly affected by evil, the lung qi is damaged due to long-term disease, the lung function is damaged, the air mechanism is blocked, the application is publicized, the phlegm is turbid, the blood stasis is inevitable for a long time, and the lung qi is further damaged.
The main clinical manifestations are shortness of breath, wheezing, shortness of breath, superficial shortness of breath and "drama of wheezing when moving", which may be accompanied by cough, expectoration, chest tightness, palpitation, lips, purple darkness, swelling of floating limbs, etc.
The treatment of chronic respiratory failure patients with COPD can be significantly improved clinical symptoms such as shortness of breath and wheezing, reduce the number of acute exacerbations of patients, but there is still a lack of high-level evidence-based medicine research.
Therefore, this project puts forward the hypothesis that "syndrome differentiation therapy can reduce AECOPD of COPD".It is proposed to adopt a multicenter, randomized, double-blind, placebo-controlled trial design, taking the patients with chronic respiratory failure caused by chronic obstructive pulmonary disease as the research object.
The patients who meet the inclusion criteria, are divided into heart lung qi deficiency and lung kidney qi deficiency according to syndrome differentiation.
The participants are randomly divided into the experimental group of 60 cases and the control group of 60 cases.
The control group is given placebo treatment, and the experimental group is given Chinese medicine granules.
The patients were followed up for 26 weeks.
The main outcome indicators include the number of times of acute exacerbation of COPD, and the secondary outcome indicators include all-cause mortality, severity of acute exacerbation of COPD, clinical symptoms, CCQ score of COPD clinical questionnaire, quality of life score, dyspnea score, 6MWD, arterial blood gas analysis index, incidence and use time of mechanical ventilation, use time of oxygen therapy, serology index, health and economy Learning indicators, safety indicators, etc.
To establish the TCM treatment scheme of chronic respiratory failure of COPD, reduce the acute aggravation of AECOPD, improve the clinical symptoms, improve the quality of life, reduce the mortality rate, preliminarily explore the mechanism of action, and lay the foundation for further research.
