Fulminant myocarditis is an acute diffuse inflammatory disease of myocardium. It is characterized by acute onset, rapid progress and high risk of death. Its pathogenesis involves excessive immune activation of the innate immune system and formation of inflammatory *** to China’s practical experience, the adoption of the “life support-based comprehensive treatment regimen”(with mechanical circulation support and immunomodulation therapy as the core) can significantly improve the survival rate and long-term prognosis. Special emphasis is placed on very early identification,very early diagnosis,very early prediction and very early treatment.

OBJECTIVE: To summarize the evidence from Traditional Chinese Medicine(TCM) practice in the treatment of acute primary headache and provide clinical practice guidance. METHODS: The guidelines were developed in accordance with the World Health Organization guideline development manual. After the establishment of steering committee, panel and the registration and protocol formulation, the evidence on TCM for acute primary headache from published guidelines, clinical evidence, and expert experience and consensus were collected. The grading of recommendations assessment, development and evaluation method was used to grade the evidence and make the recommendations. RESULTS: Based on the available evidence, the guidelines recommended three TCM herbal decoctions, six Chinese patent medicines, and two kinds of external application of Chinese herbal medicines. Diagnostic recommendations based on the expert experience and consensus were also included in the guidelines. CONCLUSION: TCM diagnosis and treatment of decoction, Chinese patent medicine and external application for treating acute primary headache were recommended. We hope these guidelines will be helpful in standardize the TCM acute treatment of primary headache.
